iLux Integrated Lighting System Crestron CLS/CLSI-C6 & CLS/CLSI-C6M

Appendix C: RS-232 Commands

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 converter 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 from the third party controllers.
