DL-1275 Ticket Dispenser Connections

The Deltronics DL-1275 ticket dispenser has the following interface on it:
Connector on back of DL-1275 Ticket Dispenser
Connector on back of DL-1275 Ticket Dispenser.
Number of pins 4
Moulding type receptacle
Contact type sockets
Pitch (pin spacing) 0.198in (5.03mm) a/k/a ".093 series" by molex
Pin 1 Blue: Notch sensor. Floats to 12V, pulled to GND when notch detected.
Pin 2 Black: GND
Pin 3 White: Apply +12V to enable dispensing motor.
Pin 4 Red: +12V

Within Iceball, OEM cabling switches over to a 12-pin AMP connector. We have not studied the pinouts.

Skeez Ball Connection

It may have been a good idea to use the same pin assignments as the dispenser on our circuit board, but this did not happen.

Pin 1 !RUN (white) : Pull to GND to enable dispensing motor

Pin 4 !NOTCH (blue): Floats to 12V, pulled to GND when notch detected.

Controller

Below is a simple controller for the DL-1275. Pull !DISPENSE momentarily low to start dispensing. As long as you pull it low long enough to get past the ticket notch, the circuit will then keep the dispenser running until it encounters another notch.

The READY line is pulled low when the dispenser is running. Once dispensing moves past the ticket notch, READY will remain low until until the next notch is encountered and the dispenser shuts itself off. At this point, !DISPENSE can be pulled low again to start dispensing the next ticket.

If READY immediately returns to high after !DISPENSE is floated, then the dispenser is out of tickets. If READY never returns to high, the dispenser is jammed.
