Setting Up Your System
Receiver and 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 Agilent E645x
receiver using the RS-232 cable included with the system. The default
serial port used by the application is multiplexed serial, COM1. If your
PC uses a different COM port, you can specify a different serial port
number.
3. Connect the RF antenna to the RF input of the Agilent E645x receiver.
Use the supplied Type-N to TNC adapter, if necessary.
4. Connect the GPS RS-232 port of the Agilent E645x receiver to the GPS
RS-232 port of the adapter box, using the RS-232 cable.
5. Connect the RTCM port of the Trimble-supplied communications cable to
the differential GPS receiver, using the RS-232 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.
6. Connect the digital port of the adapter box to the Digital IO port of the
Trimble Placer GPS 455 unit, using the RS-232 cable.
7. Connect the MDT/RTCM port of the adapter box to the MDT port of the
Trimble-supplied communications "T" cable, connected to the
Differential, using the RS-232 cable.
8. 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.
9. Connect the VHF Differential GPS antenna to the Differential GPS unit.
10. 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.
11. Connect power to the differential GPS unit, the Trimble Placer GPS 455
unit, and the PC.
