Note: The PLS-345 features a 10Base-T network interface. When connecting the PLS-345 to a 100Base-T interface, most router switches will autosense to determine if the device is 100Base-T or 10Base-T, and then configure the network interface accordingly. If your router switch does not autosense, the network interface port must be manually set to 10Base-T.

For more information on the Monitor feature, please refer to Section 5.7.
Monitor Input Connector: A two pin connector, which is used to attach the ground and input lines for an RS-232 line or contact circuit that you wish to monitor. When properly configured, the PLS-345 can perform A/B switching based on the signal level at the Monitor Input Connector. For more information on the Monitor feature, please refer to Section 5.7.
