3 Operations
The ATS-6511 is used to extend the timing signals provided by the ATS-6501 over fiber optic
cabling to accommodate transmission over long distance and improve signal integrity.
3.1 Front Panel
The ATS-6511 has several front panel indicators to provide the operator with the overall status of
the unit and will provide a visual alarm indication if a problem with the hardware or the unit
detects a condition that would cause the output signals to be outside of their timing specifications.
More detailed status information can be retrieved using the status command on the Command
Port.
