WIRING INSTRUCTIONS
DETERMINING THE NUMB ER OF WIRES REQUIRED
Use this section as a guide to determine the wires needed for installation.
STEP 1 - AC POWER WIRES (240 WATTS 115/1 20V 50/60 HZ)
Power is supplied by the Power Board.

1 x 12ga. Green Earth Ground

1 x 14ga. White Electronic Power - Neutral

1 x 14ga. Black Electronic Power - Hot
STEP 2 – RS-485 PAYMENT MODULE COMMUNICATION WIRES
The electronics communicate using a 3-wire RS-485 communication. RS-485 is a communication interface that uses multiple receivers for
signaling. Follow the recommended color-coding found in the wiring diagram.

1 x 18ga. Violet RS-485 (+ positive)

1 x 18ga. Common

1 x 18ga. Yellow RS-485 (- negative)
RS-485 wires should be twisted together no less than 3 turns per foot to reduce the effects of electrical noise on the communication
circuit. Due to the risk of noise, causing possible problems with communication, Bennett highly recommends the use of twisted wires, but
does not require it.
Note: Belden shielded cable is accepted but the “drain” must not be terminated.
POINT OF SALE (POS) COMMUNICATION
Data for the payment module is received through the [J5] connector on the SBC2 board. The module communicates directly to the Point
of Sale through the Site Master and Interconnect Box. The Site Master only carries the data from its point of entry [J5] on the Power
Board to [J5] on the modules SBC2 Circuit Board. There is nothing in the Site Master that interfaces with this communication.
