PCI-8254 / PCI-8258
3.11 Compare & Trigger Output
PCI-8254/PCI-8258 provides 2/4 comparing trigger pulse output
channels. Each comparing trigger channel can output pulse
commands up to 1 MHZ. See Section 4.9.2 for its detail and how
to use it. See below for corresponding pins of pulse command
output against differential pulse signals to DIN-825-GP4:

J3 Pin No Signal Name Description
2 TRG2-/TRG4- Trigger output (-), (2)/(4)
3 TRG2+ / TGR4+ Trigger output (+), (2)/(4)
4 TRG1-/TRG3- Trigger output (-), (1)/(3)
5 TRG1+/TRG3+ Trigger output (+), (1)/(3)
NOTE NOTE
The compare trigger pulse output channel of
PCI-8254/PCI-8258 employs line driver output interface for
better noise signal resistance and wiring length where trigger
output (3) & (4) require #2 DIN-825-GP4 for wiring.
