Relay Matrix Switch Command Reference 47Chapter 3
Comments Enabling Trig Out Port: When enabled, a pulse is output from the Trig Out
port after each scanned switchbox channel is closed. If disabled, a pulse
is not output from the port after channel closures. The output is a
negative going pulse.
Trig Out Port Shared by Switchboxes: Only one switchbox configuration
can use the selected trigger at a time. When enabled, the Trig Out port
is pulsed by the switchbox each time a scanned channel is closed. To
disable the output for a specific switchbox, send the OUTP OFF or 0
command for that switchbox.
One Output Selected at a Time: Only one output (ECLTrg 0 or 1; TTLTrg
0, 1, 2, 3, 4, 5, 6, or 7; or EXTernal) can be enabled at one time. Enabling
a different output source will automatically disable the active output. For
example, if TTLTrg1 is the active output, and TTLTrg4 is enabled,
TTLTrg1 will become disabled and TTLTrg4 will become the active
output.
