Spectracom SecureSync User Manual

If the Mode is set to Broadcast, messages in the Message Buffer will be output imme-
diately through the RS-232 Output port. If another event is captured while a message is
being sent, it will be queued in the buffer until the first message completes, then the next
message will be sent.
If the Mode is set to Request, messages in the Message Buffer are only sent when the
Request Character is received.
The output format used is selected among a small group of formats with the capability to output
data at 5ns resolution. Event Broadcast Output formats are detailed in "Time Code Data
Formats" on page518.
