NOTE

Any unused pins should be left unconnected.

Mating Connector Suggestions

A suitable mating connector is: AMP P/N 5-554739-3. This connector requires a
crimping tool to mate with a flat 8-way cable.

Alternatively, several suppliers provide a pre-fabricated cable and plugs, such as
the Digi-Key IDC modular cable assemblies range.

Speaker Suggestions

The speaker output is sufficient to drive a small magnetic transducer such as the
DB Products Ltd. MDX01C Magnetic Transducer. We recommend that you
connect the speaker output to a miniature active speaker such as the Archer Mini
Amplifier Speaker, Model # 277-1008C
to provide increased audio levels for use
in noisy environments.

3.5. I/O Connector

The 8-pin I/0 connector (located on the right hand side of the MP215’s front
plate) is not used by the MP215.

3.6. RF Antenna Connector

The antenna connector on the MP215 is a standard TNC female, 50 ohm
connector and should be used with a 50 ohm Cellular antenna with a bandwidth
from 824 MHz - 894 MHz and 0 dB gain. These are available from multiple
suppliers in various configurations (e.g. magnetic mount, hard-mount, direct
connection to the modem).
