Databits

8

Parity

N

Stopbits

1

Mask/Sync Time

Mask

0

PDOPmask

99.9

SV synctime

1.0

Positioning Mode

Lat/Long/Hght or Lat/Long

(NB: this is one setting)

Remote Protocol

4000 A/S compatible

GENERAL PROCEDURE FOR SETTING UP AND TESTING TRIMBLE RECEIVERS:

  1. Cycle through all the control functions and set the controls to the values defined above.
  2. Start the HyperTerminal program and set the required COM port to the correct I/O parameters. At this juncture no Trimble data should be visible on the screen.
  3. Turn on one of the cycle printouts, defining the port to which the QINSy system is connected.

    The ASCII position printout is useful for this purpose. Using the HyperTerminal program, check that you are receiving the position printout correctly. If no data is being read, check the interface settings and all the electrical connections.
  4. Turn off cycle printout, and, using HyperTerminal, check that no data is being received.
  5. Make sure the interface settings in DB Setup are set correctly, and start the Online module.
  6. After a short interval of perhaps 10-20 seconds, raw ranges should be displayed on the observation page of the Online module, if the connection is working correctly.

Interfacing Notes

This directive is applicable when interfacing the Trimble 4000 directly to the QINSy system, in the case where a Trimble OSM interface box is not supplied.
If a longer cable is needed, just make a direct 2-2, 3-3 and 7-7 connection from the DB25 end to the multiple COM board (e.g. Digi 8e).
