Note: If GPS is being imple-
mented, you require either two
antennas or a combination RF
and GPS antenna.
Note: Do not connect the MP
modem to a USB port on a
computer before installing the
software.
• Radio frequency (RF) antenna and cable. The antenna
must have the appropriate regulatory approval, 50 ohm
impedance, and a male TNC connector. It may be a hard or
magnetic-mounted antenna.
• GPS antenna and cable (optional). This is necessary if you
use the built-in GPS module.

sensor, gauge, or other I/O device is installed.
