Figure 3.6 illustrates the timing input/output connectors available for multiple purposes including
modulated IRIG-B, unmodulated IRIG-B, 1 PPS, programmable pulse, open drain pull down, and
event input. For information on driving multiple devices connected in parallel from a single output
connector, see Chapter 9, Timing, IRIG-B and Pulses.

Connecting I/O Signals
Terminals are Phoenix-type with 5 mm spacing and will accept between 0.25 mm to 2.5 mm
(24 AWG to 14 AWG) diameter wire. For option boards that have terminals for output connectors,
see the respective section, by option name, in Appendix B for details about those options and
connectors. BNC connectors, on installed option boards, are female.
To connect wires to the terminal, strip the insulation back to expose about 6 mm (1/4 in) of
bare wire. DO NOT tin with solder. Insert the stripped wire into the terminal and tighten the set
screws clockwise to secure.
