System Requirements
This section describes the system
requirements for the SeeGull MX Scanning
Receiver.
Typical System
Various hardware and software components
may be used in the scanning system along
with the SeeGull MX Scanning Receiver.
However, a typical configuration will include
a host PC
running the user’s application
software with a USB cable connection to the
scanner.
Antenna Requirements
Use a 50 Ohm impedance antenna with an
SMA male connector at the end of the
cable. Re
fer to PCTEL’s product offering
matrix in
Section 9
for part number
information.
Power Source Requirements
The SeeGull MX Scanning Receiver uses
10 to 16 VDC using the cigarette lighter
cable or the 12 foot battery/fuse box cable
(measured at the battery connector) and
draws 6.0 amps (nominal) @ 12 VDC. The
maximum current rating is 10 amps. The
scanner can be powered by a vehicle
battery, a 12-volt battery, or an AC/DC
adapter. The power source must be capable
of supplying the receiver with the voltage
and current levels as above. PCTEL
HIGHLY recommends that the power supply
voltage not exceed the working range of the
SeeGull MX Scanning Receiver. Applying
excessive voltage to the receiver will void
the unit’s warranty.
The scanning receiver must be powered
through the power cable provided by
PCTEL. The power cable is equipped with
an additional tab to sense the voltage drain
of the vehicle’s battery or if the vehicle’s
ignition is turned off. This feature is called
Ignition Sense Feature
and is very useful
to prevent the vehicle’s battery from
discharging if the scanner is left on when
the vehicle is turned off. In order to prevent
the scanner from draining the vehicle’s
battery, the ignition sense wire turns off the
scanner when it senses the vehicle ignition
has been off for 30 minutes or the available
power drops below the usable voltage. The
wire connects to any fuse socket on the
vehicle that has power when the vehicle’s
ignition is turned on.
Note, for ignition
sense to operate, the application
software must support this feature. If
the application does not support ignition
sense, the connection of the ignition
sense wire is not required.
Use of another power cord will void any
warranties and may result in an unsafe
condition. Refer to Section 7.1 for further
details on power cord troubleshooting.
Software Requirements
Option 1:
SeeHawk
PCTEL’s SeeHawk (
), a data
collection software package, allows for
control of PCTEL’s receivers and data
acquisition without the need for users to
Note:
Outdoor antennas, including those
used by other devices, should be placed a
minimum of 6 in. (15 cm) apart, with a
recommended distance of 34 in. (86 cm).
