7705 SAR-A Ports
ToD Out Port
The ToD port uses an RJ-45 connector to send Time of Day and phase synchronization from
the 7705 SAR-A. Only output signals are supported. The port includes an RS-422 1 pulse per
second signal and an RS-422 serial time of day signal.
Shielded cable must be used to maintain EMC compliance.
