For installations that include external modems or other peripherals, the PMU provides configuration options for the serial port power supply. The software supports three modes: disable serial port power (power for the modem is disabled), always power serial port (power to the modem is permanently enabled), and interrupt serial port power (power is interrupted for 20 seconds at a programmable interval between 1-24 hours). This granular control helps ensure correct operation of connected devices while preventing power-related issues.
The Power Master Unit platform is designed to handle complex data structures while maintaining field-level reliability. Its core architecture balances deep device configuration with automated data harvesting. 1. Comprehensive Device Configuration Elster Metering Systems Power Master Unit Software
