A typical printout looks like this:

UTC 93.12.21 20:21:16 56
UTC 93.12.21 20:21:17 56
UTC 93.12.21 20:21:18 56

If a and b are ??, the time is based on the receiver clock because the 
receiver is not tracking satellites. The receiver clock is less accurate 
than time readings extracted from satellite signals.

To enable or configure the 1PPS output function, you need the GPS 
Configurator software.

You can use GPS Configurator to configure a Trimble GPS receiver 
connected to your office computer. For more information, see GPS 
Configurator Software, page 70, or refer to the GPS Configurator 
Help.

To enable 1PPS output:

1.

Connect the computer to the Trimble R7 receiver.

2.

Turn on the receiver.

3.

To start GPS Configurator, click 

, then select 

Programs / Trimble / GPS Configurator / GPS Configurator.

The GPS Configurator dialog appears and the software 
automatically connects to the receiver.

4.

Select the Serial outputs tab.

5.

Select the 1PPS (port 2 only) check box.

6.

If you want ASCII time tags enabled, select the check box and 
choose an output port.
