CRESTRON CNX Infrared & Serial Expansion Card: CNXIR-8 Description Functional Description The CNXIR-8 Infrared & Serial Expansion Card provides for infrared (IR), ASCII, or other serial communication and control. IR output is rated up to 1.12 MHz. Serial protocols include RS-232. NOTE: RS-232 levels provide a 0 – 5V range, which may not be compatible with all devices. Physical Description The CNXIR-8, shown below, is a circuit board fastened to an aluminum faceplate.
CRESTRON Leading Specifications The table below provides a summary of leading specifications for the CNXIR-8. Dimensions are approximations rounded to the nearest hundredth unit. Leading Specifications of the CNXIR-8 SPECIFICATION Power Requirements IR Output Output Signal Levels SIMPL Windows CNX Operating System CNX Monitor Dimensions DETAILS 24 VDC, network power; 3 Watts Up to 1.12MHz 0 to 5VDC (compatible with most RS-232 input devices) Version 1.19.08 or later Version 5.01.00 or later Version 2.
CRESTRON Preparation for Use Connections are made to the eight serial outputs for IR, one-way RS-232, or serial interface. Each output is labeled S (signal) and G (ground). Refer to a sample hookup diagram below and aside from reapplying power to the control system last, complete theconnections in any order.
CRESTRON 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.
CRESTRON Graphical System View of CNXIR-8 and CT-3000 in SIMPL Windows’ Configuration Manager Click on the CNXIR-8 in slot #1 of the CNMSX-PRO to display all the IR ports of the card in the Detail System View area of the Configuration Manager. To assign specific IR devices, select them from either the Crestron or User Database which is available from the Device Library. Both are sorted by manufacturer or device type.
