Managing Power
This chapter describes how to power the receiver and use an external power source.
Turning the Receiver On/Off
1. To turn on the receiver, connect either a serial or Ethernet cable from the unit to a power source.
2. To turn off the receiver, disconnect either the serial or Ethernet cable from the unit.
Once the cable is disconnected, the receiver will begin an internal shutdown process lasting approximately 1 to
1.5 minutes. During this process, the receiver is not receiving power, but the power LED remains on until the
end of the shutdown process.
After shutdown, the receiver will begin the startup process lasting approximately 1 to 1.5 minutes. Some
receiver functions may be available during this process. All functions of the receiver are available when the
startup process completes.
Powering the Receiver
The receiver is powered by an external power source connected to either the serial connector or Ethernet
connector.
Connect to an External Power Source
To power the receiver with an external power supply, connect the SAE connector to a power supply operating
between 9 and 36 volts.
Power Cycling
If power is removed from the receiver, it will take up to two minutes for a complete shutdown. When the receiver
is powered on, it will take approximately one minute for a full reboot.
Use a 5A fuse if connecting directly to a vehicle DC power source.
Power input greater than 36 VDC could damage the receiver.
