CNX Infrared & Serial Expansion Card: CNXIR-8
Operations Guide - DOC. 8124
How the Program Works
A basic CNXIR-8 SIMPL program is shown below in block diagram form. For this
example, the CNXIR-8 occupies slot #1 of a CNMSX-PRO. Assume a touchpanel
interfaces directly with two IR drivers. Port A contains a Sony ST-92TV IR driver
and Port C contains a Panasonic AG-1980 VCR IR driver. Both drivers are obtained
from the Crestron Database. The touchpanel directly activates buttons on the IR
drivers, which closely simulates a user pressing buttons on the remote. As long as a
button is held on a touchpanel, the IR command tied to that button is sent out.

How to Create the Program
Use the Configuration Manager workspace in SIMPL Windows to select and
configure all the devices that need to be included into the system. For this example,
add a CNXIR-8 to slot #1 of the CNMSX-PRO. Also add a CT-3000 to the system;
its NET ID must be set to 03, shown on the next page.
NOTE:
SIMPL Windows v1.19.08 or later is required to program the CNMSX-
PRO. If using an earlier version of SIMPL Windows, Crestron recommends a
SIMPL Windows and operating system upgrade.
