3.1 Install TDS-6 Time Distribution Server Extension Unit
Description
Installing a TDS-6 unit involves connecting to an RS422 GPS time source
output from a TDS-2 module. The synchronized time signals travel from
the TDS-2 CHAIN port to TDS-6 extension unit through chain cables.
The signals travel to DAG cards through the TDS-6 unit synchronization
outputs.
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.
