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 />
