The COMBICON type connector, P1, has straight slot small screwdriver tightening
clamp attachment for the wires. The unit has reverse polarity protection and the wires can
be easily swapped if needed.
The dc power requirement is 8.5 to 15 V dc at less than 3 A. Current demand is larger for
the higher RF power settings. It is suggested to use 18 AWG.

GPS Antenna
If your unit has a GPS receiver, the GPS antenna transmission line connector, E1P1, is
attached to the GPS connector, A2W1J1 that is on the front panel to the lower, far right
side.
11.3
Serial I/O
The Serial I/O connector, A2J9, near the center of the front panel, is for RS232
communications, normally with a PC. Be sure to use a shielded cable that is properly
terminated. See note in § 4.4 FCC Notice concerning shielded cables. The radio modem
is considered a DCE unit. Use a straight through RS232 cable and not a null modem
cable.
11.4
Antenna
The ANT connector, A1J1, located in the middle lower portion of the front panel, is an N
(female) type for attachment of your transmission line that connects to your antenna.
The antenna (radiating element) shall not be connected to the radio modem directly, as
the RF field could induce EMI in the unit. Space antenna away from unit at least 0.6 m (2
feet).
Refer to § 4.1 RF Exposure for FCC RF human exposure requirements.
11.5
Mounting of Unit
Method of mounting is left to the customer. For best heat dissipation the finned heat sink
on rear of unit should be vertical for natural airflow. Do not exceed the maximum
operating temperature.
An optional mounting kit is available. Please call Kantronics.
