Contemporary Research Corporation 13 IR TV Controller
RS-232 Responses
iC-Net devices will send a response over the network whenever there is there is a change in status or command
from an IR remote or front panel.
Response String Structure
Characters in response strings are expressed in a combination of hex and ASCII characters. For clarity, the
following protocol examples use the following conventions:
• ASCII characters or strings are shown enclosed in single quotes
• Numbers shown that are not in single quotes are a single decimal byte
• Parameters shown in < > brackets are single byte
• A series of multiple commands or parameters are set apart by [ ] brackets
• Commas separate the bytes, but are not part of the protocol
• Double quotes enclose the command string, but are not part of the protocol
Command format:
“ ‘<’,<dh>,<dl>,<nrb>,<rb1>, <para1> [<rbN>]"
‘>’ Starts the response
<dh> The zone or high order byte of the device
<dl> The unit or low order byte of the device (0 for global zone)
<nrb> The number of response bytes to follow
<rb1> The first response byte
<para1> Associated parameters, if any
[<rbN>] Multiple responses may be included
Response Description
New Channel T “ ‘<’,<dh>,<dl>,2,'T',<new channel>" (6 bytes)
Sent in response to T? command.
IR Function F “ ‘<’,<dh>,<dl>,2,'F',<IR Function>" (6 bytes)
Sent when unit receives a new function command is pressed (1-8) or released (0) from
the IR remote.
