WARNING: Disconnect primary power prior to servicing.
• Exc Active: (Off or On) When on, this exciter is on the air.
• RF Present: (Off or On) This is an indication that the RF level at the output of the ex-
citer is above a given threshold level. The RF presence threshold is an RF output level 
of approximately 5 mW.
• Board Type: (UHF or VHF) Interface configured to fit existing UHF and VHF exciter 
interface connections.
• Board Rev: This is the board revision for the External I/O board.
• CPLD Rev: This is the software revision level of the CPLD in the External I/O board.
• EEPROM: (Ok or FAULT) The EEPROM is the local board memory. It stores board 
specific information such as board type, board revision, CPLD revision, and other lo-
cal data.
Note
Within any of these screens, touching Home returns to the main
screen, and touching Fault brings up the Exciter Status screen.

Figure 3-26  External I/O Diagnostics
The External I/O Diagnostics screen is shown in Figure 3-26. 
Analog loopback: Choices are Enabled or Disabled. Disabled is the normal setting. 
• This function loops an analog output back through an analog input channel for diag-
nostics purposes.
The last two screen entries are Analog Output A and Analog Output B. These two entries
provide a voltage for the analog loopback test mentioned above.
• Analog Output A is looped back through analog Analog 1 and 3 inputs and Analog 
Output B is looped back through Analog 2 and 4 inputs, see external I/O Board screen 
Figure 3-25 for the analog inputs.
