J5 – Trigger Signals Connector
The following figure is the DB9 male connector view when looking at the X64-AN Quad connector
bracket. The four X64-AN Quad trigger inputs use opto-coupler isolation circuits. A 650 ohm resistor
is in series with the anode. Trigger input cable (number OC-VIPC-QDTRIG, "DB9 to four BNC") is
available to simplify connecting to trigger signal sources.
See section “External Trigger” on page 41 for details on using the trigger inputs.
