2.2.5 USB Ports
The USB ports on the rear panel allow:
• Users to access the command port (94000-115200). See section 2.2.2.2. Users can
set the IP Address on the box following the instructions on section 2.2.3.B-C. The
system will automatically connect to the command port and provide the ATS-6501>
command prompt.
• The ATS-6501 to communicate with a 5071A Cesium Clock (94001-5071A). See
section 2.6.
Note: Microsemi recommends if you are going to use these cables they should be plugged into
the unit when it is powered on. If not, power the unit down, connect the desired cable(s) and
power the unit back up.
