Help 

The Help menu displays the serial 
number of the device, the version of the 
firmware, and the URL of GPS Source 
for service and support. 

Instructions 

10.  press middle (down) button until ‘Help’ 

appears on screen 

11.  press ‘Enter’ 
12.  View information specific to product by

Antenna Power On Off 

The Antenna operation turns the 
antenna power on and off .   

Note: Antenna power is on the input 
port.  This action does not affect the 
output port, so this will not turn off 
power to the devices powered by the 
output port provided the output port it is 
a pass DC(PDC) port. 

 

 

 

 

Antenna VDC  

Displays the voltage that is available to 
power the output ports.   
 
Note: this only displays the voltage 
available to the ports.  If a port is DCB 
(DC blocked) then this does not mean 
there is voltage present on the port only 
if a port is enabled to pass DC (PDC) 
will  the voltage be available on the 
port[s].  So no matter what this reads 
there will only be voltage on a port if it is 
PDC.
