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 ROS and only one can be active at any time. For information about
activating an input, refer to the RUGGEDCOM ROS User Guide for the RUGGEDCOM RS416P.
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)
• Red – Error
• Off – No signal detected
