Operation
Verify Serial Port – Connect to terminal program, like “HyperTerminal” or “Portmon” and monitor activity on serial port. Each time
another ILLUMRA device transmits, a few copies of the data packet should flow through to the serial port.
The data received from the modules contains non-printable characters. In order to see the exact contents of the received packets, set
up a text capture with Transfer->Capture Text. An alternative to the text capture method is to run a serial port monitoring program
(use Google to search for “portmon” which is available as a free download from microsoft.com, and can display the hexadecimal values
during serial operation).
Save the file in a convenient location.
Serial Data Structure
The structure of the serial data is as follows:

Unknown transmitter ID received
(serial telegram only if no ID has been learned so far!)
For RPS also:
-- Known transmitter ID and unknown rocker
-- U-message from known transmitter ID received
For HRC also:
-- Known transmitter ID and unknown rocker
-- Scene switch command (last three bits of ID 0b111) from known
transmitter ID (only first 29 bits are compared!)
Operating
Mode
0b 001
For 1BS and 4BS: Known transmitter ID received
For RPS: Known transmitter ID and at least 1 known rocker (1 or 2 rockers
operated)
For HRC: Known transmitter ID and known rocker
Operating
Mode
0b 010
New transmitter learned (If a switch telegram is received (RPS or HRC),
the rocker code (RID) is stored together with the ID.)
• Mode 3: a telegram with this header information will be sent also when
in LRN mode a transmitter which is already learned is operated again
Learn Mode
0b 110
Mode 0: Transmitter just deleted (If a switch telegram is received (RPS
or HRC), the rocker code (RID) and module ID are checked. The entry is
only deleted if module ID and rocker are known.)
