3.2.2 Rear Panel
The rear panel of the RTA is where all of the external sensors are connected. Each connection is
detailed below:
3.2.2.1 Power
Amphenol connector carrying DC power, 12-30V. This will interface with the power supply part number
3015-0001-0000 or another power supply previously supplied by Odom with the same connector.
3.2.2.2 1PPS In
1PPS can be introduced to the RTA in one of 2 ways. Firstly is a BNC connector marked ‘1PPS In’,
which connects via a length of Coaxial from the GPS providing 1PPS. The second method is through the
GPS I/O pin 9 (see paragraph 3.2.2.3 below).
The accepted 1PPS is the standard GPS output (1ms square waveform every 1 second). A limited
number of devices output a 1 second square waveform (also known as flip flop) – this will not be
accepted by the RTA.
By default, the system is configured to accept the PPS pulse through either the BNC connector or pin 9 of
the GPS I/O RS232 connector. Either one should be used for the PPS, not both. Some GPS devices
such as the C-Nav 2050 & 3050, however, output other signals on pin 9 of their RS232 that may interfere
