✓ GSM/GPRS Communications Module for Elster Three Phase Meter
The ASLH308 is a GPRS communications module for enabling automatic meter reading for Elster A1140 three phase meters. The ASLH308 is an established and well proven telemetry module which can be programmed to operate in GSM, GPRS or SMS mode. The module connects to the meter’s RJ12 socket located under the terminal cover which provides power and communications interface to the meter readings.
✓ TCP/IP Communications Link
When in GPRS mode the ASLH308 operates like a normal IP connection. The module comes with a network roaming SIM card for multi-network utilization. This creates a reliable communications link for automatic meter reading on the Openmetrics web portal.
✓ AutoRegistration Installer Service
Installers can use the AutoRegistration web service for checking new installations have connected to the network. This gives installers confidence that the meter is ready to provide automatic meter readings.
✓ SMA connector for external aerials
The ASLH308 has an internal antenna which is bridged to the modem by connecting the two flying leads together. An external antenna booster such as the Patch or SuperPatch can be connected to the SMA connection on the black fly lead to boost the signal quality to the meter.
✓ LEDs indicate communication mode
The 3 LEDs on the module indicate the network registration status, call status, and signal strength. These are red, green and amber respectively. More information on how to read the LEDs can be found in the installers guide.
