Configuring ShowShifter to work with Tira

Latest IR Tuner for ShowShifter (v1.0, Nov 20, 2003) can be downloaded from here.

Using TiraTuner you can setup ShowShifter to automatically switch channels on your cable box or a satellite receiver. This is very useful if you want to record programs while you are away.

Download and unpack the file into the following folder on your computer:
C:\Program Files\Home Media Networks Limited\ShowShifter\Config
(Assuming Windows is installed on a drive C:)

Setup TiraTuner

  1. Run TiraSSTuner.exe.
  2. Select the virtual COM port on which Tira is installed and click "Open Device". If the port is selected correctly, the blue circle will turn green
  3. Click on a number "1" button in the window. This will switch Tira into a capturing mode and a message "Recording" will appear in a status bar. Point the remote to Tira and press a button "1" on a remote until the status bar becomes empty again.
  4. Repeat procedure for the rest of the buttons.
  5. You can then check that all IR codes are properly recorded by changing mode to "Test IR codes" and clicking on number buttons. Tira will transmit IR codes as you click on buttons.
  6. Specify maximum number of digits in the channel number that your equipment has
  7. Specify whether leading zero should be used. For example, if you receiver has a maximum channel number 999 (3 digits) and you want to set it to channel 7, do you have to enter 0-0-7?
