This document is a compilation from numerous posts that describes the setup of a USB-UIRT, Tira-2 IR Transceiver as well as a TiVo-style direct connect cable for channel changing a Set Top Box.

Description

Because of my local cable provider’s move to full digital, they no longer provide Set Top Boxes (STB) with firewire ports, my preferred way of channel changing. The cable provider used to provide Motorola DCT6200 & DCH3416 STBs. They now provide Arris (formerly Motorola) DCX3220e STBs. The DCX3220e has a 3.5mm IR extender port that you can connect a TiVO style direct connect cable then connect the other end to the STB for a no-fail channel change change solution.

Direct Connect Cable

The direct connect cable: If you search on Amazon, eBay, or Weaknees for, “TiVo to DTA / Cable Box Infrared (IR) Direct Connect Cable. Replaces IR Blaster,” you will find the 34” cable or go to the link: https://www.weaknees.com/tivo-direct-connect-cable.php

This cable fits either the USB-UIRT or Tira-2's 1/8" (3.5mm) external ports. Of course, run the other 3.5mm plug to the STB's EXT IR IN port. So, no IR blaster emitter required. Note: The adapter cable can be extended with a standard, 3.5mm audio extender cable.

IR Blaster Setup

For USB-UIRT: http://www.usbuirt.com/, and if you run Mythbuntu, the Mythbuntu Control Centre will provide you essentially a turnkey solution for the blaster setup, except make [LOAD_MODULES="false"].


For comparison, my hardware.conf files looks like this:

#Don't start lircmd even if there seems to be a good config file

#It will then populate all other variables without any user input
#If you would like to configure lirc via standard methods, be sure
#to leave this set to "false"
FORCE_NONINTERACTIVE_RECONFIGURATION="true"
START_LIRCMD=""


The following is the hardware.conf for the Home Electronics Tira-2 (my preferred IR Transceiver): https://home-electro.com/products/tira-21

For Home Electronics Tira-2, you may have to make a unique transmitter lircd.conf file (dctxxxx.conf) using tira_raw. Note the following link for the reason why: http://www.lirc.org/html/tira.html

To accomplish this, use the cable provider remote that works with your STB. Mine is the UR4U remote that works with Arris/Motorola boxes. Point it at the Tira-2, then:

  sudo killall lircd
  irrecord -H tira_raw -d /dev/ttyUSB0 DCT2000-tira


Result was the following:

Note: For Tira-2, I had to use "--device=/dev/lircd1" for irsend to work.
