Enfora Enabler IIIG M2M
Modem Integration Guide
As part of integration, each of the following interfaces must be verified:
Information
Recommendations
SIM
The maximum line length of the SIM interface is 25.4
cm (10 inches).
The Enfora Enabler IIIG module takes care of the signal conditioning
As a minimum, an external application with a remote SIM will require a
standard SIM carrier.
Filter the SIM VCC signal with a 10 uf / 10 V capacitor to help with the line
length.
Primary and
secondary serial
Interfaces
The Enfora Enabler IIIG module uses a 1.8V digital interface. The RS-232
signals must be level-shifted to get standard levels. These signals must be
ESD-protected.
Reset Interface
Resets the Enfora Enabler IIIG module when tied low.
Audio/Microphone
Interface
Preliminary balancing on Enfora Enabler IIIG module.
Maximum length TBD
