2.4. System Requirements
This section describes the system
requirements for the SeeGull EXflex
Scanning Receiver.
Typical System
Depending on a user’s requirements,
various hardware and software components
may be used in the scanning system along
with the SeeGull EX
flex Scanning Receiver.
However, in most cases, a typical
configuration will include a host PC
connected to the scanning receiver via a
USB cable and running th
e user’s
application software.
Antenna Requirements
Use a 50 Ohm impedance antenna with an
SMA male connector at the end of the
cable. Refer to
PCTEL’s product offering
matrix in the back of this document for part
number information.
Power Source Requirements
Maximum power the SeeGull EX flex
Scanning Receiver draws:

21 watts (max)

17 watts (typical)
Voltage range for the EX flex Scanning
Receiver:

8 to 16 VDC
Use a car battery, a 12-volt battery, or an
AC/DC adapter. It is imperative that the
power source be capable of supplying the
receiver with the voltage and current levels
as described above. It is HIGHLY
recommended that the power supply not
exceed the working DC voltage range of the
scanning receiver. Applying excessive
voltage
to the receiver will void the unit’s
warranty.
The scanning receiver should be powered
through the power cord provided by PCTEL.
If another power cord is used, the power
cord must be one that incorporates a fuse
for protection and safety purposes or this
will void any warranties.
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).
