To make a terminal connection, connect a serial cable (specifications on page 30) between the user terminal and the 9 pin DIN female connector on the VEEMUX-A labeled "RS232". (See Fig.
NTI AUDIO/HD VIDEO MATRIX SWITCH Power Up 1. 2. 3. Connect the IEC power cord to the VEEMUX-A and plug the cord into an AC power outlet. Turn ON power to the VEEMUX-A using the switch above the IEC socket. Turn ON power to the video and audio sources, and the video and audio devices connected to the VEEMUX-A, if they are not already ON.
NTI AUDIO/HD VIDEO MATRIX SWITCH CONTROL OPTIONS The VEEMUX-A video matrix switch has four methods of control: • Front Panel LCD with Keypad • Directly via an RS232 Interface • Remotely via Ethernet (web interface) • Infrared Remote (optional). Every unit comes standard with the Front Panel LCD with Keypad, RS232, and Ethernet connection built-in. If desired, the Infrared option must be requested at the time of the order.
NTI AUDIO/HD VIDEO MATRIX SWITCH Volume Control The volume level can be adjusted on each output port. • To increment <▲> or decrement <▼> the volume, use the following command: , <▼>, Double digit output port number, <▲> increment or <▼> decrement, Ex 1: <▼> 03 <▲> <▲> <▲> This will increment the volume by +3dB (1dB/ step). Ex 2: <▼> 14 <▼> <▼> This will decrement the volume by -2dB.
NTI AUDIO/HD VIDEO MATRIX SWITCH Scan Mode Scan Mode causes output ports (audio and video) to automatically switch from one audio and video input port to the next consecutive audio and video input port after a specified period of time (referred to as the dwell time). Audio and video port switching will continue indefinitely and no ports will be skipped, whether there are audio or video sources connected to them or not.
NTI AUDIO/HD VIDEO MATRIX SWITCH 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.
NTI AUDIO/HD VIDEO MATRIX SWITCH Command Protocol CPU 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 CPU 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.
NTI AUDIO/HD VIDEO MATRIX SWITCH Set Volume Level For Output/User Port (for command string AV SW,OP,VV in chart on page 11) This command will set the volume of the specified AUDIO output/user port from a scale of 00 to 99, which represents a logarithmic volume.
