Appendix C: RS-232 Commands

Operations Guide – DOC. 6347E
Connect the third party controller to the serial port of the C2N-IO. Connect the
C2N-IO to the CLS-C6s Local Devices – G Z Y 24. ASCII commands received by
the serial convertor module are sent to the CLS-C6 slave Cresnet port. The CLS-C6
Cresnet serial packets are forwarded as ASCII strings to the third party controllers.
Only one C2N-IO device is allowed on the local Cresnet network. The Cresnet ID
for the C2N-IO should be set to 00 so that the iLux can assign D5 when auto-
discovery is run.
NOTE: When connecting the C2N-IO serially to the PC ensure proper wiring. The
Tx pin of the C2N-IO serial connector must connect to the Rx pin of the serial
connector on a PC. Additionally, the Rx pin of the C2N-IO serial connector must
connect to the Tx pin of the serial connector on a PC, and then ground.
NOTE: If the PC is connected to the CLS-C6 and the C2N-IO (serially) at the same
time, then choose a different port for the C2N-IO since the serial connection is not
shared (COM1, COM2, ... COM6). This can be performed in the Crestron Toolbox
Address Book when selecting the communications settings for the C2N-IO.

Command Format

All packets from the third party equipment shall be in ASCII character set range 0 to
127. Extended ASCII characters higher than 127 are not supported. All command
and reply packets for the third party controller between the CLS-C6 and C2N-IO
devices are in Cresnet serial packet type 0x12 format. The serial packet payload
contains the ASCII command or reply strings form the third party controllers.
