Table 5.2: Timing Output Jumper Selection
NOTE:
Values for ‘X’ in IRIG-B00X (unmodulated) and IRIG-B12X (modulated) are 0 if the
IEEE 1344 is ON, or 3 if IEEE 1344 is OFF. Configure the IEEE 1344 function in the IRIG-B
setup menus; see Section 7.9.13 and 7.10 for details on
setting the IEEE 1344 Extension
. For a
brief definition of the IEEE 1344 Extension, see Chapter 8.

Configuration Notes
1. To set Output 1 as unmodulated IRIG-B (5 VCMOS, demodulated, or level shift) set jumper
JMP10 = A and jumper JMP11 = C. Similarly, to set Output 2 for unmodulated IRIG-B,
set JMP12 = A and JMP13 = C.
2. To set any output as modulated IRIG-B, set only one jumper. For example, to set Output 2
as modulated IRIG-B, set jumper JMP13 = B. Jumper JMP12 is not required.
3. To set any output as programmable pulse, use two jumpers. For example, to set Output 3
to programmable pulse and 300 V FET, set jumper JMP14 = C and JMP15 = A. Note that
Programmable Pulse A configures Outputs 1 and/or 2, and Programmable Pulse B configures
Outputs 3 and/or 4.
4. Remember to configure any IRIG-B timing output from the front panel for the UTC or
Local time zone and whether you want IEEE 1344 ON or OFF. See Figure 7.20 for setup
information.

Configuring Relay Mode Jumpers
The Model 1094B has one set of Form C relay contacts that may be configured to alarm (or trip)
for a Fault, for an Out-Of-Lock condition, or according to the Programmable Pulse A function. By
default, the relay is connected to indicate an unlocked condition. When the 1094B is unlocked (i.e.
not tracking GPS satellites) the red, UNLOCKED LED, should also be lit to indicate an unlocked
condition. See Table 5.3.
NOTE:
If configuring relay contacts for programmable pulse, use only Programmable Pulse A
Mode.
