In RS232 mode, the RJ45 ports conform to EIA-561 DTE, which transmit on TXD and receive on RXD.
Note
Pins 7 and 8 are connected internally. In RS232 mode, these pins enter a high
impedance state. A DTE that asserts RTS will see CTS asserted. However, the device
will not perform hardware flow control.

Inputs are controlled by RUGGEDCOM RS416PF and only one can be active at
any time. For information about activating an input, refer to the
RUGGEDCOM
RUGGEDCOM RS416PF User Guide
for the RUGGEDCOM RS416PF.
The color of the
Sync
LED on the front panel of the PTP module indicates the status
of the incoming timing signal:
•
Green
– Signal locked
•
Amber/Yellow
– Holdover (GPS lock has been achieved, but the receiver no
longer sees the minimum number of required satellites)
