  • Page 7: About This Manual

    2.0 PRODUCT INFORMATION The Protected Network Station (Figure 1) is a tabletop or rack-mount unit designed to hold two GE MDS transceivers, two power supplies, and a switchover logic board that automatically selects between trans- ceiver A or B as the active transceiver. Manual transceiver selection may also be made using a front panel switch.

  • Page 8: Product Features

    Invisible place holder Figure 1. Protected Network Station With two transceivers and power supplies installed, the unit will con- tinue to communicate even if a failure occurs in one of the transceivers or its associated power supply. This capability is important in mis- sion-critical applications where uninterrupted service is required.

    When an alarm condition exists, the transceiver creates an alarm code or message that can be read on a PC terminal connected to the rear panel port. This information can be helpful in resolving many DIAGNOSTICS system difficulties. Consult the transceiver manual for a discussion of alarm messages and corrective action.
