•
An illuminated LED indicates an active port and if it is in Source or Receiver mode.
•
If the Source (amber) or Receiver LEDs (green) are not illuminated, the port is terminated.
•
If all of the odd numbered ports are Off, Port 1 of the PNA-X is active.
•
If all of the even numbered ports are Off, Port 2 of the PNA-X is active.
Standby Switch
This switch is Standby only, not a line switch. The main power cord can be used as the system
disconnecting device.
Active LED
When the Test Set is connected and addressed by a PNA-X, the LED is On (illuminated). The
LED is Off (not illuminated) when the Test Set is in Standby, or not addressed by the PNA-X.
When two Test Sets are connected together, as in the 24-Port system, the first
Test Set connected to the PNA-X will never have an "On" Active LED. Instead,
the last Test Set in the I/O cable chain will be the Test Set showing the "Active
LED" status for all.
