6.16. IRIG-B
•
Synchronise the relay with the date and time of the PC that is being used to communicate with the unit.
•
Check that the relay and the PC show the same time.
•
Place in the IRIG-B receiver a date/time completely different from the current time, which is on the PC.
•
Connect the IRIG-B receiver to the relay.
•
Check that the relay and the IRIG-B receiver show the same date/time.
