Installation Installation 1. Turn OFF power to all video sources (inputs) that will be connected to the VEEMUX-A before connecting or disconnecting any cables. 2. For each video source, connect a VEXT-xx-MM cable from the video port of the source to a video input (VIDEO-1) of the VEEMUX-A (see Fig. 1). 3. Repeat step 2 for remaining video sources. 4. For each audio source, connect a SA-xx-MM cable from the audio source to the port labeled AUDIO IN 1. Notes: The audi

RS232 Control RS232 Control Remote Connection The RS232 Interface is designed to control the switch via serial (RS232) daisy chain connection from any host computer or other controller with an RS232 communications port. There is, however, a restriction that must be followed: A program must be used that will send an entire command line all at once, not character by character. (The HyperTerminal program in WINDOWS cannot be used, as it sends each character one at a time.) The pin outs for the DB

Command Protocol Host controller commands supported by the unit are defined below. All commands should be terminated with a (carriage return). When a command is sent, the entire string is echoed back to the host along with a response from the addressed unit as shown in the command definitions. All characters should be upper case, and all numbers below 10 should have a leading 0 (ex: 1 = 01). NOTE: For units with one output or user port, use 01 for the output select. RS-232 Command Protocol

DDC Support (Optional) DDC Support (Optional) DDC information allows the CPU to automatically select the optimal resolution for the monitor by receiving, at power up, information from the monitor concerning its resolution specifications. When DDC Support is installed, the DDC information is acquired from the monitor by the VEEMUX-A switch when the VEEMUX is powered-up. A monitor with DDC support must be connected to MONITOR 1 for this to occur. The DDC information will be made available at eve
