5.2.2 Digital Outputs: Port 1 and Port 3
Ports 1 and 3 provide identical digital signal choices, and setting their respective jumpers are the
same. Available digital signals from these two ports are unmodulated IRIG-B, programmable pulse
and pulse per second (1 PPS). These two ports may also be jumper-ed to a 200 volt FET for pull
down applications. Additionally, each port may be used as an event input. One set of jumpers sets
the type of signal and another set of jumpers sets the signal source. Tables on the following pages
