Background:
Communication with the PC-Remote is simple. It's just like using a standard universal remote controller, but you 'virtually' press and release keys by sending the PC-Remote commands over your serial port.

Send a key press sequence:
To send a key press command to the PC-Remote, you follow this sequence:

This four step process is all you need to know to begin sending IR commands to your audio/video equipment.

Programming the PC-Remote for your devices:
The PC-Remote can be programmed for up to 4 devices, but since you can write your own applications to send commands, you can use the PC-Remote to control as many devices as you wish. Just reprogram it on the fly!

Step 1: Select the source to program (Source 1, Source 2, Source 3, or Source 4)
Step 2: Send the 'Program' command (C0h)
Step 3: Wait 25 milliseconds
Step 4: Send the 'Release' command (00h)
Step 5: Send digit 1 of setup code
Step 6: Wait 25 milliseconds
Step 7: Send the 'Release' command (00h)
Step 8: Send digit 2 of setup code
Step 9: Wait 25 milliseconds
Step 10: Send the 'Release' command (00h)
Step 11: Send digit 3 of setup code
Step 12: Wait 25 milliseconds
Step 13: Send the 'Release' command (00h)

You have now programmed your PC-Remote to control the device stored in Source 1. To send IR commands, follow this similar procedure:

Step 1: Select the source to program (Source 1, Source 2, Source 3, or Source 4)
Step 2: Send the code for the button you wish to 'press'
Step 3: Wait 200 milliseconds
Step 4: Send the release button code (00h)

Binary Protocol:
HomAtion 2000 and CyberHouse cannot send binary protocol, but if you are writing your own applications, use the following protocol to communicate with the PC-Remote. Don't forget to send the 'release key' command '00' in between key presses.

ASCII Protocol: For use with the Gate Way I as the interface to the PC-Remote

If you plan to use the PC-Remote with HomAtion, CyberHouse, or any other program which uses ASCII text, but not binary, you must use the GateWay as an intermediate interface and follow the protocol outlined in Table 2:

If you are using the ASCII protocol, the Gate Way takes care of the timing. All you need to do iis send the command for the button press. With the Gate Way as the interface to the PC-Remote, you can send IR scripts within a single command.

The format in which you send commands to the PC-Remote via the Gate Way is as follows:
'Qn<Enter>' Where n is the function from the above table. Commands must be sent at 9600 baud and end with a Carriage Return and a Line Feed. To send a script, simply send more than one command at a time; i.e., QCP03<CR> will turn on the Cable box and set it to channel 3.
