The Digi radio operates on 12 VDC. A power cable is provided in the kit. The barrel
end of the wire is notched and plugs directly in to the Digi Radio. The other end is
connected to a 9-pin connector and connects in to the back of a control board, to
receive power. See Figure 6-1 Connecting Wires to Terminal Block , page 93

VDC of power. The barrel connector sleeve (ring) is negative, and the tip
(interior) is positive. If yes, order a new Digi Radio and/or power cable. If no,
diagnose and repair the control board's power source (transformer).

Two communication wires connect between the Digi radio's terminal block and a 9-pin
connector, the same 9-pin connector that the power wires connect to for a power
source. These two wires provide the signals for half duplex communication between
the Digi radio and the fryer's control board. Ensure seamless data communication
between the Digi radio and control board by doing the following:

If the Digi radio hardware is installed and operating correctly, verify the fryer's control
board (software) is communicating with the Digi radio. Refer to
