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