2 Installing the SAMMS-LV Device

enables the SAMMS-LV to communicate with a remote super- visory device. Examples of the remote supervisory device include the Power Monitor display unit, a standard personal computer running the Power Monitor PC communications and supervisory software, or Siemens Microsoft® Windows™ based SIEServe™ or WinPM™ software. These supervisory devices and programs can communicate with the SAMMS-LV device and allow it to operate in the ACCESS electrical distribution

communications system.

The SAMMS-LV device connects to the SEAbus™ RS-485 via the 5 pin plug on the Communications Module CM-1. The communications connections are illustrated in Figure 2.3. Refer to Installing the ACCESS System (manual no. SG-6028), for detailed information on connecting the SAMMS-LV device to the ACCESS network.
