• Compact Form Factor

The COM3000 offers up to 138 channels of HD video and integrated Edge QAMs in only 3RU of rack space. This compact design also results in dramatic power savings compared to typical stacked receiver solutions.

• HD Content Protection

For High-Definition solutions that require copy protection, the COM51 receiver blades add Pro:Idiom™ or Pro:Idiom Mobile™ encryption to the HD content, which can be played back on any Pro:Idiom™ or Pro:Idiom Mobile™ enabled receiver device or television.

• Integrated Edge QAM

Available as a plug-in module for the COM400, the QAM20 reduces overall system costs and simplifies the installation and maintenance for the COM3000. The QAM20, sold as a 16-channel QAM, and can be software upgraded to a 48 channel QAM device two channels at a time, capable of delivering all 138* streams of DIRECTV™ HD content as well as additional local sourced content.

*Three DIRECTV streams per QAM are possible on a properly balanced system—please ask your distributor or Technicolor for more information.

• Remote Management

The COM3000, including all the receiver blades and Edge QAMs, can be managed and monitored remotely over the Internet or local network using a simple web browser-based management interface.

The COM400 includes an integrated 10 Gigabit Ethernet backplane with two 1 Gigabit and two 10 Gigabit Ethernet ports available on the front panel. It contains two slots for up to two QAM20s to be inserted, for a maximum of up to 96 QAM channels; and six receiver slots, for up to a total of 138 DIRECTV HD streams, utilizing the COM51 receiver blades and SWCOM51 tuner licenses.

The COM400 provides all the receiver blades and QAM20s with a commercial grade power supply drawing less than 225W of power when fully loaded. This cuts the power usage by more than half when compared to a comparable stacked receiver head-end system and provides for tremendous savings in yearly Operational Expenses associated with video distribution systems.

The COM400 also provides commercial grade cooling fans in order to meet the grueling demands of harsh commercial environments.

• 2 x QAM20 Edge QAM slots
• 6 x Receiver slots (COM51, COM51A, COM46 or COM46A)

• No more than 225W power consumption fully loaded
• Can be daisy-chained with new or previous COM systems for higher channel count installations

As the newest in a family of DIRECTV receivers specifically designed for the commercial market, COM51 adds a new level of density capable of tuning up to 23 high-definition channels as well as capable of tuning DIRECTV 4K content and outputting this content over IP with either Zenith Pro:Idiom™ or Pro:Idiom Mobile™ content protection for HD and 4K broadcasts. The IP output can either be aggregated and distributed using an existing IP network, or it can be sent to the integrated QAM20. The COM51 can also simultaneously send it’s channel streams to an IP network and QAM without the need for duplicating channels.

The COM51 comes standard with 8 active tuners and can be expanded, via one license tuner at a time to a max of 23 HD channels.

• 8 HD or SD channels
• MPEG2 and MPEG4 support
• UDP/RTP Video Outputs
• 2 RF SWM or digital SWM inputs

• Add up to 15 SWCOM51 Tuner Licenses
• LED Status Indicators
• Can be daisy-chained with new or previous COM systems for higher channel count installations
• Pro:Idiom™ & Pro:Idiom Mobile™ content protection

Distribution of content typically requires the use of an Edge QAM device to distribute digital content using an RF cable network. The QAM20 is designed specifically for the COM3000 and fits perfectly into the bottom slot of the COM400 chassis. It provides for sixteen channels of QAM and can modulate 48 HD streams of DIRECTV. Although you can install two QAM20 Edge QAMs in a COM3000 this will only be needed for high levels of local content insertion or 4K content.

The QAM20 can be easily upgraded to an max of 48 QAM, two at a time using a SWQAM2 key which can be applied to the device. This allows you to maximize the efficiency of the Edge QAM for many specific application.

External content from IP sources can be routed through the QAM20 for RF distribution. This includes content from external sources such as a PC, video camera, or other IP converter.

• DIRECTV™: Supports up to 3 HD programs per QAM
• Able to mix HD and SD content on and QAM channel

• Accepts MPEG over IP content from external sources
• 2 Channel software license purchase available to upgrade to a maximum of 48 total QAM channel

Overview

DirecTV supplies and has supplied a variety of set top boxes (referred to as 'STB' from here on) to consumers. Nearly all of them have the ability, although not directly advertised, to be controlled from an external device, such as a MythTV BackEnd.

Cable Options

WARNING: Not all USB to Serial port adapters are compatible with linux. There are a few well known ones that are made with compatible chipsets (the PL-2303 comes to mind), but there are many more that do not work with any flavor of linux. Please choose your cable with care.

WARNING: You MUST hit the red reset button for many DirecTV receivers to recognize USB-to-serial adapters. The docs that say the port is hot-swap are lying. Further, neither rebooting from the UI nor yanking the power cord is sufficient. Apparently, that red reset button does something particularly special....

Known good adapters are:

1. The Sabrent USB->Serial port adapter (http://www.newegg.com/Product/Product.aspx?Item=N82E16812156008)
   1. WARNING: I ordered one of these and it no longer works with the DirecTV box. These are now using the pl2303X chips instead of the pl2303 and do not work.
2. IOGEAR GUC232A, ATEN UC-232A (pl2303), BAFO BF-810, QVS UR-2000M2, Sabrent SBT-USC1M and other PL2303 based adapters are known working.
   1. WARNING: I ordered two of these (Sabrent?) and they no longer work with the DirecTV box. These are now using the pl2303X chips instead of the pl2303 and do not work.
   2. A new IOGear GUC232A unit worked for me on 2010-06-17, so either they still use the older rev (unlikely) or DirecTV upgraded to a newer Linux kernel that fixes the driver bug with the new revision (likely).
3. http://www.cablestogo.com/product.asp?cat%5fid=1529&sku=26886
   1. July 06, 2007 Update: It has been reported that EMTC (http://www.emtcompany.com/products/adapters/dxubdb9-usb-to-serial-db9-adapter-cable.htm) is no longer shipping linux compatible (PL2303) cables. Previously, they were a good and inexpensive supplier, but the replacement cables are not compatible. DO NOT BUY THESE
4. GWC UC320 (http://www.newegg.com/Product/Product.asp?Item=N82E16812107108). This has been reported to work on both the HD20-100 and D11-500 boxes as of November, 2007.
5. http://www.dtvcontrol.com/index.aspx?content=cable, which shows up under linux as 'Prolific Technology, Inc. PL2303 Serial Port'
6. Dynex DX-UBDB9 purchased off of ebay (February 2009 and August 2009) work fine on the H20-600, H20-100 and H21-200.
7. Paterson Technology USB TV Translator. Works flawlessly on an H23 receiver (also works with D11, D12, and H20) and has additional logic to eliminate the channel banner quickly.
8. Other cables/adapters are unknown (use at your own risk).

Be careful, a lot of these adapters are no longer pl2303 based although they carry the same Model number. Try http://www.cooldvr.com. He carries a complete set of cables (pc or mac to stb) that are tested to work. Cost about the same as buying the parts individually

Official USB to Serial Cable Support

According to the Installers Guide V2.2, the following USB to Serial Adapters are fully supported:

Therefore, it is possible (though not guaranteed) that your particular USB-Serial adapter will work if it has:

• USB Vendor ID= 0x067B
• USB Product ID= 0x2303

To find this out, use the lsusb command after plugging in your device. If it shows a line of output like the following, it should theoretically work.

Directv H23-600 Hd Receiver Manual Last Version Download

The USB port on most set top boxes (STBs) should support hot-plugging. However, if you are having troubles with your USB-Serial adapter, try plugging it in before the STB is booted. Particularly, the Installer's guide mentions that the HR20 and HR21 work this way. To do this, simply:

1. Unplug the STB
2. Plug in the serial adapter
3. Plug in the STB and wait until it boots

Afterwards, make sure your device on the mythtv box is correct when you pass it to the script. For me, it was /dev/ttyUSB0.

A simple test command for using the correct device is the following:

If you get 'Error excessive retries', you probably are using the wrong serial port. Set it with the port command as in the above example.

The D10 & RCA Satellite STB

Many of the older (pre 2007) STB's that were sold or leased by DirecTV have a small phone-style port on the back of the unit that is labeled as 'Low Speed Data Port' or simply 'Low Speed Data'. This port, although it can be initially be mistaken as a standard RJ-11 phone jack, is actually quite a bit smaller (in technical terms, it is called an RJ-22) and is sometimes referred to as a 'mini RJ-11' port. If you take a look at the coil handset cable on your non-cordless phone (you still have one of those, right?), you will see that the plug on that cord is the same as the port on the back of the STB.

You will need the following components in order to create a connection from your MythTV backend to the STB:

1. a USB->Serial Adapter (USB Male to 9-pin Male)
2. a handset cord for a corded phone
3. a Serial->RJ45 adapter
4. a short length of ethernet cable with RJ-45 connectors already crimped down on each end

If you prefer to get your hands on a modular serial hood, you can omit the Serial->RJ45 adapter and the ethernet cable. I used the items listed above because that was what I had readily available.

The DirecTV D11/H20 Satellite STB

The DirecTV D11/H20 Satellite set top box contains a USB port that can be used as a serial port to change channels and perform other tasks on the box. To do this, you need the following cables:

1. USB->Serial Adapter (usb male to 9 male).
2. 9-pin Null-Modem Adapter (9 female to 9 female)
3. 9 pin serial cable. (9 female to 9 male)

The end result of this is a null modem serial connection between computers. I assume that using two USB->Serial adapters would also work, (see note below) given that the Null Modem adapter was still used.

I used the BAFO BF-810 adapter (found for $9 online) and a pair of 9pin DSub to RJ45 adapters wired as a crossover serial cable, along with a straight-through ethernet cable.

I started with the directv.pl script used to control the D10 box. I had to change the speed to 115200 from 9600 (contrary to the installers guide which says 9600 or 155200, which must be a typo). I also had to enable hardware flow control in order to get reliable operation.

NOTE: I was using 115,200 baud for months with two D-11 boxes. Around the middle of January 2007 I started getting channel change failures. Switching it to 9600 baud fixed it. My theory is that DirecTV sent down a firmware upgrade to change the all the D-11 boxes to 9600.

NOTE: D11 and H20 boxes require baud rate = 115200 (May 25, 2007)

NOTE: If baud rate = 115200 does not work with the H20 box using the CablesToGo usb->serial adapters, try 9600 (Oct 22, 2007)

NOTE: For Mac OS X connecting to a D11 or H20 use directv.pl ver 1.8 which supports baud rates (for Mac and Linux) >38400. A usb to serial adapter on both ends connected by a null modem cable works fine.(May 25, 2007)

NOTE: I have 2 D11 boxes hooked up to my motherboard that has only 1 serial port connection. One is connected as described above, the other uses the exact same scenario except with an extra USB to Serial adaptor to plug the cable into the motherboard's USB port. This was an extra USB to Serial Adaptor I had bought that didn't work when plugged into the D11 box, but works just fine on the other end. I now have two serial devices connected (ttyS0 and ttyUSB0) and am controlling two boxes without a problem.

The DirecTV H21 Satellite STB

While most of the info listed for the H20 should be applicable to the H21, here are a few specifics of usb->serial adapters which did and didn't work in addition to the configuration and directv.pl settings.This particular setup is: H21 <-> USB/serial converter <-> null modem adapter <-> mb serial port

Keep in mind that there is also this possible combination:H21 <-> USB/serial converter <-> null modem adapter <-> USB/serial converter <-> computerwhich was not tested.

The following parameters were given to the directv.pl script (v1.9):box_type H20 baud 9600 port /dev/ttyS0

The DirecTV H23 Satellite STB

This STB works as well using the H20 commands, version 1.9 of the script and the USB to USB cable set from http://www.cooldvr.com/Buy.html, but it works better for me using the direct channel change command rather than the keypress command. (probably a delay timing thing, but sometimes it would miss the keypresses. it would do this directly from the remote control as well, so it may just be my particular unit) Everything else in the H20 command list seems to work.

DirecTV H24 Satellite STB

The latest version of DirecTV's set top box is the H24. It has a USB port like the previous versions. The directv.pl script (see the External Links section below to download the script) works to change the channels using the H20 'box_type'. I used a usb-serial converter with a PL2303 chip and a null modem adapter to hook it to the serial port on the motherboard.

Making Your Own Custom Cable (D10/RCA)

You can either buy a cable to convert from the low speed data port to a serial port from http://www.dtvcontrol.com/index.aspx?content=cable or, using the pinout either on that page or within this page (they are the same),you can make one on your own.

Overall difficulty of making your own cable is rather low. Take your time, and be prepared to test it once (or twice) before taping everything up to make sure you got it right.

Using the items listed aboce, I grabbed with the handset cable, two serial to RJ-45 adapters, and a short RJ-45 ethernet cable and I:

• Cut the headset cable in half, giving me two pieces of the same approx. length.
• Cut the RJ-45 cable in half giving me two pieces of the same approx. length.
• Cut back the outer sheathing on the RJ-45 cables at the point where I cut it in half.
• Cut back the outer sheathing on the headset cables at the point where I cut it half (this was a pain)
• Cut back the sheathing on the individual exposed wires on the RJ-45 cables and the headset cables.
• Plugged the RJ-45 cables in to the Serial-RJ45 adapters.
• Using a 9-volt battery and a cheap DC tester, I mapped out what pins on the serial side of the adapter mapped to which exposed wires on the cut end of the RJ45 cable. WRITE THEM DOWN. I cannot stress this enough. Because you will be dealing with two different wires, it is easy to get confused. I have these written down at home, and, after making my third adapter, I can tell you that the entire mapping is usually custom since serial-to-RJ45 adapters are not all created equal, the handset cables are not always color coded, and you can use any variant of RJ45 cabling.
• Using your mapping of the serial port adapter to the individual wires in the ethernet cable, write down the proper mapping of the wires from the handset cable to the individual wires of the ethernet cable.
• Following the mapping you just created, hand twist the appropriate wires together and use electrical tape to hold it.

Because I had the DC tester (with the little light on it), I was able to do a final test of the completed connection to confirm that the wires were connected properly. Connect the serial port end to either your MythTV backend's serial port, or, if you don't have one available (most machines now-a-days don't have more than two, and many only have one), plug it in to the USB->Serial port adapter, and plug the USB->Serial port adapter in to an available USB port. Plug the other end of the cable you just made (the mini RJ-11) in to the STB.

Now, test it and make sure it changes channels./usr/local/bin/directv.pl setup_channel 10

If it does not work, you will get something on the command line like 'excessive retries to port' or some similar error. This means, more than likely, that you reversed the mapping of the pins. I say this because that is exactly what I did. I had looked at the mini RJ11 port, and the exposed wires (all of the wires on the one that I had were the same color: gray!) and asked myself 'Which end is pin 1?'

Custom Channel Change Configuration

In order to configure MythTV to call the directv.pl script, you must add the command with desired options to the tuner section of mythtv-setup( User Manual:Detailed configuration Backend ).

1. Run mythtv-setup
2. Select Input connections
3. Choose the connection you would like to control
4. Add the script to the External channel change command parameter

For example, I set mine to...

The help text for this parameter says, 'If specified, this command will be run to change the channel for inputs which have an external tuner device such as a cable box. The first argument will be the channel number.' I interpreted this to mean that the channel will be added to whatever is specified here. This would mean that parameters could be added such as [hide, retries_number n,...]. It appears that once a command is sent like 'hide' it is persistent. So you could specify it in a command window at any time.

Watch out for Xwindows using the serial port by default

In some stock /etc/X11/xorg.conf files, a serial mouse may be configured by default. If this is the case, you may notice unreliable communication with your directv box. Channel changes may not function correctly, multiple timeouts, etc. can occur. You can verify that the serial port is not in use by using the lsof command. For example,

shows that X has the /dev/ttyS0 file open. We can fix this by commenting out the appropriate device section in your /etc/X11/xorg.conf file and restarting X.

udev rules

If you are using a USB->serial adapter on the computer side of things, and are trying control multiple STBs, you will likely need to use udev rules for predictable naming of the USB->serial device. Instructions for udev can be found on the Device_Filenames_and_udev page.

An example rule might look like:

SUBSYSTEMS'usb',KERNELS'5-1:1.0',DRIVERS'pl2303',SYMLINK+='STBChannel0'

In that example, the KERNELS'5-1:1.0' indicates which USB port the adapter is plugged into on the computer. If the USB->serial adaptor does not report any unique identification, using the USB port is the only way.

Directv H23-600 Hd Receiver Manual Last Version Online

Note that some distributions come with a gpsd udev rule, which can get in the way. There is probably a more 'proper' way to handle this problem, but on my system I just removed 99-gpsd.rules to fix the problem.

Working around some missing functionality on the channel change script

Note: This user may have been able to fix this problem by both: making sure his box_type was correct, and adjusting the delay sent to the script. Both options are documented in the script's help output.

In my situation, some of the features of the directv.pl script did not function in the way that I liked, or simply did not function with my STB. Specifically, with my STB, the 'setup_channel' function, which is defined in the documentation as 'turning the unit on, changing the channel, and hiding the on screen display' really only did the first two pieces, leaving the OSD up for an obscenely long amount of time. I simply wanted the script to change the channel and hide the OSD immediately.

While the directv.pl script can take the options out of order (eg: directv.pl port /dev/ttyUSB0 hide setup_channel 29), it did not seem to make any difference. This limitation required me to write a small wrapper script called '/usr/local/bin/change_channel.sh' :

I then used '/usr/local/bin/change_channel' in the field as outlined above in the 'Custom Channel Change Configuration' section. Be sure to specify the corresponding port for each of your tuners.

Serial -> RJ45 (Pin to Wire) Mapping

I used a standard SUN supplied serial to RJ45 adapter and got the following mapping of the serial port pins to the individual wires on the RJ45 cable plugged in to the serial port adapter. I also used a snort length of off-the-shelf pre-made RJ-45 (Cat5) wire.
