SmartPresenter™ Cable: SPC-121

The SPC-121 is designed for the SmartPresenter™ and used to control specific

serially-controlled devices. The entire length of the cable is approximately 15 feet

(4.572 meters) with a RJ11 (6-position, 6-pin) connector at one end and a DB9M

connector at the other end.

NOTE: Alteration of the SPC-121

in any manner may affect its

performance within the control

system. Crestron cannot

guarantee its behavior if altered.

A serially-controlled device can be controlled with the SmartPresenter™ only if the

appropriate Q-Code is assigned to OUTPUT 4 on the SP-1. The SP-1 recognizes the

Q-Code as an RS-232 switching device and outputs commands for that device to the

PC port (rather than the OUTPUT 4 port). Use the SPC-121 to connect the SP-1 to

the serially-controlled device (refer to illustration below). Only those devices with a

cable code “b” designation in the Crestron Q-Codes table (latest version of the

SmartPresenter Quick Guide, Doc. 5742) require the SPC-121.
