2. GPS antenna with pre-amp, magnetic base and SMA connector
A magnetic-mount active antenna is supplied with the receiver development kit, along with an 
RF cable (RG-316) already terminated with the proper connector for the development unit. The 
nominal measured attenuation of the cable with connectors is approximately 5 dB. The supplied 
active antenna should be biased at +3 VDC, but a different active antenna with a bias of either 
+3, +5 or +12 VDC may be used. Refer to section 3.2 to ensure that the configuration switches 
on the front panel of the development unit are chosen to select the appropriate bias voltage. 
Caution:
 ensure antenna power switches are properly set before connecting the antenna. An 
antenna designed for +3 VDC operation will be damaged if connected to a +12 VDC 
source.
3. Serial interface cable
A serial cable is provided to interface between the development unit and the customer’s PC, or 
between the development unit and a DGPS receiver. This cable is terminated at both ends with 
female connectors to match the male connectors on the development unit and the PC. If the PC 
used only supports a USB port, an RS232/USB converter could be utilised.
4. Power adapter for 240/120 VAC operation
DC power for the development unit is provided by either an AC/DC converter or automobile 
adapter. The AC/DC converter operates from a nominal 120/240 VAC input and provides a 
12 VDC at 500 mA out. 
5. Power adapter for 12 VDC vehicle operation
For mobile operation, an automotive adapter intended for use in 12 VDC vehicles is provided.
