Setting Up Your System
Phone-Based System Setup
Configuring a Trimble Placer GPS 455 and Differential
1. Connect the hardware security key to the parallel port of the PC.
2. Connect the serial port of the PC to the RS-232 port of the differential
receiver using the RS-232 straight-through cable, connected to the RS-
232 "T" cable. The default serial port used by the application is serial,
COM1. If your PC uses a different COM port, you can specify a different
serial port number.
3. Connect the RTCM port of the Trimble-supplied communications cable to
the differential GPS receiver, using the RS-232 "T" cable included with
the system. Connect the remaining port of the Trimble-supplied
communications cable to the MDT/RTCM port of the Trimble Placer
GPS 455 unit.
4. Connect the GPS antenna to the GPS ANT port of the Trimble Placer
GPS 455 unit. Agilent Technologies recommends that a "bulkhead
mount" GPS antenna be used whenever possible for improved
performance.
5. Connect the VHF Differential GPS antenna to the Differential GPS unit.
6. Connect the phone cable to a second COM port (different than used in
step 1). On most laptop PCs this will require the use of a Socket Serial I/O
RS-232 card that is installed into the PCMCIA slot on your PC.
7. Connect power to the differential GPS unit, the Trimble Placer GPS 455
unit, and the PC.
8. Turn on the differential GPS unit, the Trimble Placer GPS 455 unit, the
PC, and the phone. Refer to
configure the Agilent Wireless Solutions Software.
9. Configure the phone:
a. Select Configuration mode.
b. Select the Hardware tab.
c. Double-click the phone icon or select the phone icon and click
d. In the Hardware Type box, select the phone used.
