12.5 Antenna System
The included antenna is directly mounted on a 26 mm pole (1.05 in OD or 0.75 in ID pipe), with either a
standard 1 in – 14 (approximately M25.4
×
1.81) marine-mount thread or a 0.75 in NPT pipe thread. Other
mounting configurations are available (contact Arbiter Systems).
ˆ
GNSS Antenna Assembly: 0.75 in pipe thread mount, 35 dB gain; 3.3 Vdc to 5 Vdc.
ˆ
Optional antenna mounting bracket available to mount on 60 mm (2 in, nominal) pipe (See
section 4.1.2).

12.6.2 Setup Functions
ˆ
Serial COM1 configures port parameters; returns setup and broadcast ASCII string; transmits RS-
422/485.
ˆ
Serial COM2 : configure port parameters, return setup and broadcast ASCII string.
ˆ
Local Time & DST : set local time zone offset from UTC, and daylight saving time offsets.
ˆ
Out of Lock : Sets the time before an out-of-lock condition alarms. Can be turned off. Counts up to
45 days and clears when clock regains GNSS synchronization. See Section 8.4.
ˆ
Relay Config. : The internal relay may be set to make/break for the following conditions: (1) out of
lock, (2) fault, (3) alarm, (4) clock stabilized, and (5) failsafe.
ˆ
Back Light : Sets the back light in the LCD display to be ON, OFF, or in Auto mode.
ˆ
System Delays : Offsets the time delay in nanoseconds for the GNSS signal to pass from the antenna
to the GNSS receiver.
ˆ
Programmable Pulse : Sets the mode, interval and pulse width for programmable pulses. Also has
an auxiliary IRIG-B mode, independent from the main IRIG-B setting.
ˆ
IRIG Time Data : Sets the time zone and IEEE C37.118.1 mode.
ˆ
Event/Deviation : Set to either Event or 1 PPS Deviation.
ˆ
Option Control : Configures the option board function in the clock, if installed.
ˆ
C Display Format : Configures the date format for the large display on Model 1201C clocks to
MM/DD/YY or DD.MM.YY.
