48 Relay Matrix Switch Command Reference
Chapter 3
OUTPut:TTLTrg[:STATe]
OUTPut:TTLTrgn[:STATe] <mode>
selects and enables which TTL
Trigger bus line (0 to 7) will output a trigger when a channel is closed
during a scan. This is also used to disable a selected TTL Trigger bus
line. n specifies the TTL Trigger bus line (0 to 7) and mode enables
(ON or 1) or disables (OFF or 0) the specified TTL Trigger bus line.
Parameters
Comments
Enabling TTL Trigger Bus:
When enabled, a pulse is output from the
selected TTL Trigger bus line (0 to 7) after each channel in the switchbox
is closed during a scan. If disabled, a pulse is not output. The output is a
negative-going pulse.
TTL Trigger Bus Line Shared by Switchboxes:
Only one switchbox
configuration can use the selected TTL Trigger at a time. When enabled,
the selected TTL Trigger bus line (0 to 7) is pulsed by the switchbox each
time a scanned channel is closed. To disable the output for a specific
switchbox, send the OUTPut:TTLTrgn 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.
