ANTENNA
Primary cellular antenna connections are SMA female connectors and must be used with antenna with SMA male
connectors. When using a direct mount or rubber duck antenna, choose the antenna specific to your band
requirements. Mounting options and cable lengths are user’s choice and application specific.
The diversity antenna connector, labeled DIV, can be used for a Diversity antenna. The diversity port supports Cellular
(850 MHz) and PCS (1900 MHz) bands. Connect a dual band cellular antenna to this port to implement RX diversity on
the unit and increase receive sensitivity on the cellular network.
For mobile models equipped with Wi-Fi, the antenna connector labeled AUX is an RP-SMA female connector for 2.4
GHz Wi-Fi that facilitates 802.11 b and 802.11 g wireless networks.

POWER CABLE PINOUT
Depending on the version (fixed or mobile) of Vanguard router ordered, different power cables are provided. The
mobile version ships with a 22-foot power cable that requires a fuse (included). The fixed version ships with a 6 foot DC
three-wire power cable that does not contain a fuse. An AC power adapter is available as an optional accessory.
Regardless of the cable length, the pinout is the same and only the color of the ground wire differs (blue in the mobile
wire harness, and black in the fixed).
When installed for a fixed application or if the Ignition-sense line is not required in a mobile application, the ignition
sense line (white wire) should be shorted to V

Batt
(red wire).
