  • Page 6: Overview

    Earth is collated on the ground by GPS receivers. Receiver units can be mounted on building exteriors or elsewhere with an unobstructed sky view. A GPS receiver unit is connected to a TDS-2 module by fitting a DB25 cable to a DB25-toDB9 adapter on the module.

    TDS-6 module When additional time synchronization outputs are required, the capacity of a TDS-2 module is expanded six outputs at a time without compromising timing accuracy by attaching up to four Endace TDS6 units. One TDS-2 module with the maximum number of TDS-6 expansion modules provides 24 time synchronization outputs derived from a single external time standard.

    2.3 Connect TDS-2 Module to Code Division Multiple Access Source Description An RJ45 cable is used to connect a TDS-2 module to a CDMA source via an adapter supplied with the CDMA receiver. The module signal source selection switch is set to CDMA and the LED flashes indicate processes are occurring in relation to timing signal and SERIAL packet activity.

  • Page 13: Connect Tds-2 Module To Global Positioning System Time Signal Source

    When CDMA unit locks onto the network, the CDMA receiver’s LEDs activate, with the PPS LED flashing once per second indicating the timing signal is being received. The PPS LED on the TDS-2 front faceplate should now be flashing. 2.4 Connect TDS-2 Module to Global Positioning System Time Signal Source...

    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.

    3.0 CONNECTING TDS-6 TIME DISTRIBUTION SERVER EXTENSION UNIT Introduction Connecting a TDS-2 module to a TDS-6 Time Distribution Server unit expands distribution of global time synchronization signals to multiple destinations. The TDS-6 expansion unit provides 6 time signal synchronization outputs derived from a single TDS-2 module connection.

  • Page 17: Install Tds-6 Time Distribution Server Extension Unit

    A TDS-6 Time Distribution Server extension unit is firmly fixed in a position where cables are readily accessed without obstruction. Connecting the TDS-6 unit involves inserting the supplied chain cable to the TDS-6 CHAIN 1 port and inserting the other end into a vacant TDS-2 module CHAIN port. Figure Figure 3-2 shows the typical TDS-2 module and TDS-6 unit connection configuration.

  • Page 18: Connect Additional Tds-6 Time Distribution Server Extension Units

    A number of TDS-6 units can be coupled together like a daisy-chain to enable extension of time-synchronization output to more DAG cards or PC’s. If the two TDS-2 module chain outputs are in use, with two TDS-6 units already being connected, additional TDS-6 units can be chained to the first TDS-6 units.
