2.5.2 PC Connection to TDS-2 Time Distribution Server Module
Description
Once the TDS-2 module is fully functioning, a PC can be connected via
the module’s host connection.
The PPS signal and SERIAL data packet is then received by the PC. If the
timing signal is being generated by a CDMA receiver, the packet can be
read on a PC via a standard terminal package.
If the timing signal is being generated by a GPS, a decoding software
program, such as supplied with the Trimble Acutime 2000 Kit, needs to be
installed for on-screen display of the packet-read.
This connection can also be used to provide a reference clock to the PC in
order to operate a NTP server.
Procedure
Follow these steps to connect a PC directly to a TDS-2 module.
Step 1
Connect TDS-2 Module to PC
Use a straight-through DB9M-to-DB9F SERIAL cable.
Step 2
Check Signal Source Switch
