SIEMENS NET-4 Communication Interface Module
INTRODUCTION
The Model NET-4 from Siemens Industry, Inc. provides the communication interface between PSR-1 remote panels and the main MXL. It is a Style 4 communication interface to the MXL RS-485 network. The NET-4 permits local annunciation of ground faults at each remote MXL panel. Ground fault detection for the network itself is provided by the MMB main board. Each NET-4 connected represents one network drop on the MXL System. The total number of NET-4s permitted is 31. (The first position is always occupied by the MMB.) The NET-4 installs into the PSR-1 remote power supply. The PSR-1 provides all necessary power to the NET-4 through the card edge connector P7. There are no configuration switches or jumpers on the NET-4.
For additional information on the MXL/MXLV System, refer to the MXL/MXLV Manual, P/N 315-092036.
