Antec Fusion Black + Logitech Harmony 880 (via LIRC iMon)

Harmony 880 and Antec Fusion Black

I have an Antec Fusion Black 430 HTPC case, which has a built-in LCD and IR receiver, and I want to control it using my Logitech Harmony 880 programmable remote.

Getting it to work was a major pain.


The lirc_imon module is used to communicate with the iMON PAD. LIRC has to be configured and compiled to provide this. The LIRC daemon then has to be properly configured so that it loads the correct driver, interacts with the right device, and sends the correct virtual keypresses to MythTV.

Step 1: Verify Hardware Connection

The output of lsusb should contain a line similar to this:

Bus 001 Device 003: ID 15c2:ffdc SoundGraph Inc. iMON PAD Remote Controller

If something like this doesn't appear in the output, then the USB connector from the front of the case is probably not connected properly.

Step 2: Prepare for LIRC Compilation

The instructions for compiling LIRC leave out several necessary dependencies. They will be listed here when I find my notes.

Step 3: Compile LIRC iMon Support

Follow these instructions to download and compile LIRC for iMon support.

Step 4: Configure LIRC for iMon

Copy an appropriate hardware.conf file to /etc/lirc/hardware.conf. Here is my hardware.conf:

# /etc/lirc/hardware.conf
#Chosen Remote Control

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

#Try to load appropriate kernel modules

# Run "lircd --driver=help" for a list of supported drivers.
# If DEVICE is set to /dev/lirc and devfs is in use /dev/lirc/0 will be
# automatically used instead

# Default configuration files for your hardware if any

Step 5: Configure LIRC for the Logitech Harmony 880

copy the correct lircd.conf file to /etc/lircd.conf. Note that it does not go in /etc/lirc/lircd.conf, since lircd seems to only look for /etc/lircd.conf.

I started out with this lircd.conf file, but it's intended for a true Microsoft Media Center remote. For whatever reason, entirely different button codes are sent with my Harmony 880 configured to control a "Microsoft Media PC". Using irrecord to capture button codes, I ended up with this file:

# lircd.conf file for Harmony 880 (configured to control a
# Microsoft Media Center PC) and the Antec Fusion's iMON PAD
# IR remote controller.
# This file should be placed in /etc/lircd.conf

      end codes
end remote

Step 6: Configure LIRC for MythTV

Now that LIRC knows how to talk to the hardware (step 4), and what the button codes mean (step 5), you have to tell LIRC what virtual keypresses to generate in order to interact with MythTV. This requires that an appropriate lircrc file be copied to ~/.mythtv/lircrc. In my case, the user 'mythtv' runs MythFrontend, so the file is /home/mythtv/.mythtv/lircrc.

I used the lircrc file from's Harmony 880 wiki page.
