Pins 4 through 7 across the top of the Automation Server are labeled as "Operator Panel" although there is not an Operator Panel part available.

Building Operation Automation Server (AS)
There is no explanation of what the AS Operator Panel contacts are for?
On front of AS:
|Term 4||RET||Internally connected to ground|
|Term 5||10V||10 VDC max. 120 mA|
|Term 6||Tx/Rx+||RS-485 communication|
|Term 7||Tx/Rx-||RS-485 communication|
At one time there were plans to create an Operator Panel so terminals were reserved on the Automation Server for local OP connection, however, these plans were not implemented. The next generation Automation Server Premium (AS-P) does not have the Operator Panel label, and today most operators use Webstation or Workstation.
