8.3.5 Suppress Out of Sync Indications
This makes TCG 01 operate as if it is in sync at all times, even if there is no antenna
attached. The sync relay operation is unaffected by this option and will still indicate the
true sync state of TCG 01.
8.3.6 Suppress Outputs When Out of Sync
This option suppresses the TCG 01’s output signals on P2, P3, P4, P5 and the Time Server
when the clock goes out of sync. The sync relay operation is unaffected by this option
and will still indicate the true sync state of TCG 01.
8.3.7 Sync to IRIG-B Input
Checking this option, forces TCG-01 to get its synchronisation from an external IRIG-B
signal fed into the first input on the input plug P6 (terminals [+1, C]), overriding any
information from the GPS antenna. This feature allows multiple time code generators
from a single antenna. The slave TCG-01 receives synchronisation from a master TCG 01
that is producing IRIG-B, and will use the local time settings that are programmed into
the master TCG-01.

Programmable Outputs
8.4.1 P2 / P3 / P4-pin 1
Each of the three outputs (P
P2, P
P3 and P
P4-pin 1) can be programmed to give one of four
different output waveforms. Selection between the four options is done via a drop-down
menu. The options available iindependently for each output are:
GPS Antenna
P6 input [+1, C]
P6 input [+1, C]
TTL level IRIG-B with
IEEE extensions
(P2 or P3)
Master
Ant
Slave 1
Slave 2
