Reapply power to the CNMSX. Preparation for Use Three distinct channels are available from the CNXVTC-3 via three connectors, A, B, and C. Each connector is labeled IN (+, X, and -), OUT (+ and -), and G (ground). Refer to a sample hookup diagram below and aside from reapplying power to the control system last, complete the connections in any order. Sample Hookup Connections for CNXVTC-3 A/V EQUIPMENT UNPOWERED AUDIO OUT INPUT AMPLIFIER Input impedance and balance are determined by external connections. 8126 CNX Volume Control Expansion Card: CNXVTC-3 · 3 CRESTRON Balanced and Unbalanced External Connections BALANCED 600 OHMS INPUT BALANCED OUTPUT + X + G IN UNBALANCED 10K INPUT UNBALANCED OUTPUT + X + G IN OUT OUT Programming with SIMPL Windows® ® SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use programming language that is completely integrated and compatible with all Crestron system hardware. SIMPL Windows offers drag and drop functionality in a familiar Windows® environment. SIMPL Windows is Crestron Electronics' software for programming Crestron control systems. It provides a well-designed graphical environment with a number of workspaces (i. e. , windows) in which a programmer can select, configure, program, test, and monitor a Crestron control system. The next two subsections describe a sample SIMPL Windows program that utilizes the CNXVTC-3. The first subsection details how the sample program works with a textual description and block diagram. The second subsection provides a broad description of how to actually create the SIMPL Windows program. NOTE: The following description assumes that the reader has knowledge of SIMPL Windows. If not, please refer to the extensive help information provided with the software. A copy of this program is available from Crestron's ControlCD (version 4. 03 and later). Search for the CNXVTC-3. SMW project in the SIMPL Windows Example Base. How the Program Works A basic CNXVTC-3 SIMPL program is shown on the next page in block diagram form. Assume channels A and B are tied together to provide control over a stereo source that has a left and right channel. Channel C is for a mono source that only has one channel, such as a microphone. 4 · CNX Volume Control Expansion Card: CNXVTC-3 Operations Guide - DOC. 8126 CRESTRON Block Diagram of CNXVTC-3 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. Also add a CT-3000 to the system; its NET ID must be set to 03, shown below. NOTE: SIMPL Windows v1. 19. 08 or later is required to program the CNMSXPRO. If using an earlier version of SIMPL Windows, Crestron recommends a SIMPL Windows and operating system upgrade.
