2.1. Connections
Pin 1 low level
Pin 2 low level (common).
Pin 3 start input.
Pin 4 mode input.
Pin 5 Busy / Ready output
Pin 6 Coin Exit output
Pin 7 Power Supply (12 or 24VDC).
Pin 8 Signal common ground.
Pin 9 Power ground (0V).
You can use a 9-pin Molex connector (Suzo Part no. 22-01-2095) and crimp terminals
(Suzo Part no. 08-50-0032) or equivalent with a pitch of 0.1” (2.54mm).
Be careful with the pin numbering of the connector, because not all manufacturers start
numbering from the same pin.
Furthermore, all assemblies are connected to the main PCB with JST connectors.

Figure 1: Hopper Control Board
- The RS232 connector can be used to perform serial communication with the processor on the board.
IC 6 (Max202CPE) must also be fitted. The software contains a few commands that can be used to
control the hopper. It's not recommended to use this serial protocol for applications other then for test
purposes. Other more sophisticated protocol like CCtalk should be used for serial communication.
- The HOPPER connector should be connected to the host machine.
Refer to Table 1 for a complete pin description.
- JP1 en JP2 are jumpers that define the operation mode of the hopper. Refer to section 2 for the
jumper definitions.
- JP3 set the power supply voltage of the board.
12VDC : short pin 1 and 2.
24VDC : short pin 2 and 3.
