5
GPIO1
No connection. Reserved for general purpose input/output.
6
RX2
Auxiliary asynchronous serial data port receive (RX) line.
7
RESET
Pull low (GND) to generate a system reset. Must be held low for a minimum of 100 ns.
8
V_ANT
Provides a power connection to the pre-amp of the active antenna.
9
V_RTC
Provides a back-up power connection for the receiver
’
s Real Time Clock. 1.0 to 3.0 V DC.
10
TMARK
UTC time-mark pulse, one pulse per second. An IBM Binary message contains the UTC time
associated with the time-mark pulse.
