1.0 Introduction
Alpha’s Enhanced Digital Status Module (EDSM) is a status monitoring interface for the XM Series
2 power supply. The EDSM can monitor up to six power supplies and an AlphaGen generator. Up to
two battery strings can be monitored directly using the AUX connector and applicable wiring harness.
Battery Sense wire kits are sold separately.
The EDSM continuously gathers power supply, generator, and battery data. Data is transferred to an
industry standard digital transponder (DT) using a serial interface, specifi ed by the ANSI/SCTE25-3
standard. DT Connector equipped EDSMs (Alpha P/N 745-678-20) connect to either an embedded
digital transponder or an external digital transponder. Transponders quickly assemble and prepare
data for headend equipment and network monitoring software. The software graphically displays the
power supply status via a user-friendly interface.
Existing Alpha Technologies enclosure tamper switches are accommodated through the EDSM
tamper connector. The EDSM/embedded transponder package requires less cabling than previous
status monitoring products.
The EDSM LED indicators can be viewed day or night. In conjunction with XM Series 2 Smart Display
and status LEDs, it is easy to diagnose the health of the power system.
The combination of network monitoring software and local displays and indicators will give the
technician complete detail of the overall power system health.
The EDSM DT Connector is only used for connecting to an external digital transponder. Connecting
this port to any other device may result in damage to the EDSM and associated equipment.
