TLX Matrix Switch ASCII API V5 15 Rev. I, January 2019
Diagnostic Commands
These commands are used to test the ability of the switch to make connections. They will
connect each of the input ports to each of the output ports in one of three ways, as described below.
XTEST1
Connects all the ports on the Matrix Switch (n to n).
Connects input 1 to output 1, input 2 to output 2, …input n to output n...
Format: XTEST1
Example Result: R0003OK
XTEST2
Connects all the ports on the TLX320 and TLX640 Matrix Switches.
This test is only available on the TLX320 and TLX640, due to their underlaying hardware design and
will activate a set of hardware paths that do not exist on the other TLX models.
On the TLX320, it connects:
input 1 to output 161, input 2 to output 162, …input 160 to output 320…
input 161 to output 1, input 162 to output 2, …input 320 to output 160...
On the TLX640, it connects:
input 1 to output 640, input 2 to output 639, …input 640 to output 1...
Format: XTEST2
Example Result: R0003OK
XTEST3
Connects all the ports on the Matrix Switch for testing CATx Extenders.
Connects input 1 to output 2, input 2 to output 1, …input n-1 to output n, output n to input n-1...
Format: XTEST1
Example Result: R0003OK
Note: If you want to verify that all the outputs on the switch are working, the command
Cixxxxo9999 will connect input xxxx to ALL the output ports. The XTEST commands
require an input signal on ALL inputs, whereas the Cixxxxo9999 only requires a signal on
input xxxx.
