User’s Manual
If user enters the default command in GPS TIME SYNC UNIT MC-1-DE, then the serial terminal
communication parameters as well as network parameters gets default as per above table. User has
to set the PC Serial terminal communication parameters to mentioned default values in order to con-
tinue with configuration mode on serial terminal.
•
This default command does not affect the Manual time.
8.2.8.2 Command: R
This command will reset GPS TIME SYNC UNIT MC-1-DE.
This command will reset GPS TIME SYNC UNIT MC-1-DE unit.
As a result of which, all the outputs will be stopped or there will
be change in relay and pulse output till unit boots up again.
8.2.9 Antenna Cable Propagation Delay command:
Command: SPDxxxxx (1PPS cable correction command/Propagation Delay)
-Only available on special request
Description: The GPS Timing receiver outputs a 1PPS signal, the rising edge of which is placed at the
top of the GPS or UTC one second time mark epoch as specified by the Time Mode command. The
1PPS Cable Delay Correction command allows the user to offset the 1PPS time mark in one nanose-
cond increments relative to the measurement epoch.
This parameter instructs the GPS receiver to output the 1PPS output pulse earlier in time to compen-
sate for antenna cable delay. Up to one millisecond of equivalent cable delay can be removed. Zero
cable delay is set for a zero-length antenna cable.
The user should consult a cable data book for the delay per unit length for the particular antenna ca-
ble used in order to compute the total cable delay needed for a particular installation.
This parameter may also be employed by the user to adjust the position of the 1PPS to compensate
for other system delays.
