Antenna Input

Figure 2.6 illustrates the female type-F, GPS antenna input connector, which also supplies 5 VDC
to energize the antenna.
Figure 2.6: GPS Antenna Connector
To check for this 5-volt signal, use a small multimeter and probe from the center pin (+) of the
connector to the threads. Voltage range is 4.9 to 5.1 VDC. For further information, see Chapter 4,
Antenna and Cable Information.
2.3.3

Event Input

For timing external events based on the GPS-synchronized time, use either of two event input
connectors: J4 (Standard I/O) and J6 (RS-232C). See Figure 5.1, which illustrates the location of
these two connectors and the jumper location to select either connector.
2.3.4 RS-232 and RS-485 Communication Ports
The Model 1092A/B/C and 1093A/B/C each have one standard and one optional communication
port with RS-232 supported. RS-485 is supported only on the standard RS-232 port, not the
optional RS-232 port. The RS-232 port does not use flow control and the RS-485 is transmit only
(uses Transmit A and Transmit B, no Receive A and Receive B).
