The VDM is equipped with an AEMnet connector (power, ground, and CAN) so
that it is a true plug and play experience when used with other AEMnet products
such as the Infinity ECU.
Ideally, the VDM module should be installed near the center (both fore/aft and
side-to-side) of the vehicle and as low as possible. For example, the module
may be mounted to the floor of the vehicle between the two front seats. The
module should be mounted using the provided "hook-and-loop" material or may
be more rigidly mounted using fasteners through the module's mounting ears.
Take care to avoid over-torquing mounting fasteners, if used.
The antenna should be mounted in a location where the top is pointed towards,
and has a clear view of, the sky. The bottom of the antenna is magnetic or
additional hook-and-loop material is provided for mounting; the dashboard or rear
package shelf are
not acceptable locations. The antenna should be mounted as
high as possible in the center of a metal roof away from other antennas or
structures. If the roof of the vehicle is non-metallic then a flat piece of metal at
least five inches in diameter, to function as a ground plane, should be fabricated
upon which the antenna should be placed.
Status LED
There is a status LED located on the top of the VDM module that gives an indication of its operating status,
specifically the quality of the current GPS signal:
LED Description
OFF The device is not powered
FLASHING RED No valid GPS fix
FLASHING GREEN Less than 4 satellites in view
GREEN 4 or greater satellites in view

Channels / Data
GPS
The VDM utilizes an internal 10Hz GPS/GLONASS receiver with a matching external active antenna. Faster time to
fix, and better global coverage is afforded by the support of both the GPS and GLONASS constellations. The
module is designed with an internal battery that will retain the last known satellite position (ephemeris) while power
is disconnected from the VDM for several days. This will allow for a very fast time to fix (<1 sec typ) once the device
is turned on again; if power is removed for an extended period of time then the time to fix will increase. The internal
battery is automatically recharged and never needs to be replaced.
The following GPS channels are output on AEMnet for logging on your Infinity ECU or other device:
Channel Name Notes
GPS Latitude [deg] + = North, - = South
GPS Longitude [deg] + = East, - = West
GPS Speed [mph] Speed
GPS Altitude [ft] Above Mean Sea Level (MSL)
