TLX Matrix Switch ASCII API V5 24 Rev. I, January 2019
Appendix C: Connecting Extenders
The following are sample commands needed to connect selected transmitters and receivers through
a TLX Matrix Switch. These examples will reference the appropriate Quick Start Guide.
A) VEL-24 through a TLX320
Quick Start Guide: VX320Video_VEL-24_VEL-38_QSG
Number of fibers: 3: L1, L2, L3
Backchannel fiber: L2 (data from receiver to transmitter)
Tx24 fiber connections Rx24 fiber connections
• L1 -> 14R L1 -> 15T
• L3 -> 16R L3 -> 16T
• L2 -> 14T L2 -> 15R
Commands: (all upper case)
CI0014O0015 Connects L1 video to RX L1
CI0016O0016 Connects L3 video to RX L3
CI0015O0014 Connects L2 data to RX L2 (backchannel)
Assume a second receiver is now connected as follows:
• L1 -> 25T
• L3 -> 26T
• L2 -> 25R
The commands to connect this receiver to the transmitter are:
CI0014O0025 Connects L1 video to RX L1
CI0016O0026 Connects L3 video to RX L3
Note: Receiver 2 (L2 backchannel data) is NOT connected.
• Receiver 1 has full keyboard/mouse/USB/speaker access.
• Receiver 2 has sound (speakers) but no keyboard/mouse/USB.
To move the keyboard/mouse/USB from Rx 1 to Rx 2, issue the following commands:
DI0015 Disconnects RX 1 L2 (backchannel)
DI0025 Disconnects RX 2 L2 (backchannel)
CI0025O0014 Connects RX 2 L2 data to TX 1 (backchannel)
or
M001500000015000000150014 Macro command that combines all three commands
The two 'DI' commands are sent to insure the keyboard/mouse data only goes to a single
transmitter. If you are certain that there are no other L2 connections in place, you may eliminate
them.
Warning! Eliminating the 'DI' commands will open the possibility of sending keystrokes
and/or mouse commands to multiple servers at the same time – a situation that will lead
to disaster! Always ensure that no other L2 backchannel connections are in place before
eliminating the 'DI' commands!
