Procedures to Transfer Time
These procedures are used to transfer time between a fine clock and a cold or warm clock GPS receiver.
Transfer COARSE Time (<10 ms) from a Fine Clock to a Cold Clock GPS Receiver
1. Connect a COM, USB or Ethernet port from the fine clock receiver to the cold clock receiver (for
example, COM2 on the fine clock receiver to COM3 on the cold clock receiver) as shown in
Transfer COARSE Time from Fine Clock to Cold Clock Receiver
on page 69. Configure both ports to the
same baud rate and handshaking configurations.

2. Issue the following command to the fine clock receiver:
log com2 timesyncb ontime 1
3. Issue the following command to the cold clock receiver:
adjust1pps time
When the cold clock receiver receives the TIMESYNC log, it sets its clock with a 100 ms transfer delay
allowance.
The
OEM6 Family Firmware Reference Manual
(OM-20000129) contains details of the logs
mentioned above.
When connecting two receivers to transfer time, disable responses on the COM port used to
connect the receivers by issuing the following command on both receivers:
interfacemode comX novatel novatel none
Where comX is the port used on the receiver.
