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 either GPS 
Configurator or Configuration Toolbox.

You can use GPS Configurator to configure a Trimble GPS receiver 
connected to your office computer. For more information, see GPS 
Configurator Software, page 78, or refer to the GPS Configurator 
Help.

1.

Connect the computer to the 5700 receiver.

2.

Power on the 5700 receiver.

3.

To start GPS Configurator, click 

, then select 

Programs / Trimble / GPS Configurator / GPS Configurator.

automatically connects to the 5700 receiver.

4.

5.

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