Time-Of-Day Input
An RJ45 connector is provided on the front panel of the RTM-ATCA-F140 for reception of serial
RS-485/RS-422 time-of-day information from a GPS receiver. The serial format is 9600 baud,
8data bits, no parity, and 1 stop bit. There is also a 1PPS input channel on the RJ45 connector
for GPS receivers that transmit 1PPS serially. Below is the pinout of this port:
