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-124 to connect the SP-1 to
the serially-controlled device (refer to illustration below). Only those devices with a
cable code “d” designation in the Crestron Q-Codes table (latest version of the
SmartPresenter Quick Guide, Doc. 5742) require the SPC-124.
