Change Unmodulated IRIG-B to Programmable Pulse

To change the output signal at pin 1 of J4 from IRIG-B unmodulated to Programmable Pulse, drill
the via at JMP3 and install a zero-ohm jumper or a short piece of wire as shown on the PC board.
5.3.3

Change 1 PPS to Programmable Pulse

To change the output signal at pin 5 of J4 from 1 PPS to Programmable Pulse, drill the via at
JMP4 and install a zero-ohm jumper or a short piece of wire as shown on the PC board.

I/O Connector Used as Event Capture Input, JMP7

With modification, the Model 1092A/B/C and 1093A/B/C can accept an Event Capture input
through connectors J4 or J6 (I/O and RS-232 respectively). See Figure 5.1. To select the RS-232
input from J6, set jumper JMP7 to the "A" position
Input from J4, set jumper JMP7 to the "B" position. The event capture circuit will, once armed,
capture the time of occurrence of the start bit of the next received character (see Section 7.10,
entitled "Setting the Event or Deviation Modes").
Selection of one of the I/O connector pins for event capture (in place of the normal output
signal) is done by a hardware modification, which is generally performed at the factory at the time
of initial order. If this has been done, it will be indicated by the "EVENT INPUT" label above
the appropriate pins of J6. Then, setting jumper JMP7 to the "B" position will enable an external
5 V CMOS-level signal to drive the event-capture circuit.

Available on boards with serial numbers beginning with four digits greater than 9636. For boards with serial
numbers beginning with 9636, this jumper is not available, and the only event input possible without a board
modification is RS-232.
