12 VDC Model- Connect +12 VDC to Pin 11 (Red wire) on the 18-pin connector (see Figure 1).
Connect DC Ground to Pin 4 (Black wire) on the 18-pin connector.
In addition, both the 120 VAC model and 12 VDC model have an "Out of Service" output located on Pin 10
(Tan wire) of the 18-pin connector. It is a normally high, open-collector output transistor that is pulled low
when the acceptor is Out of Service. (5-12 VDC at 40 ma Max.) Pin 13 (White/Orange wire) of the 18-pin
connector has a 330 ohm resistor tied to +5VDC to power an LED.
Outputs
120 VAC or 24 VAC Model- You can use the relay output on Pin 7 (Brown) and Pin 8 (Blue) of the 9-pin
connector, or you can use the normally high, open-collector output transistor on Pin 1 (Brown wire) on the
18-pin connector. (5-12 VDC at 40 mA Max.)
12 VDC Model- Use the normally high, open-collector output transistor on Pin 1 (Brown wire) on the 18-pin
connector (5-12 VDC at 40 mA max.)
All outputs will send the number of pulses and pulse speed as set by the Configuration Card.
RS-232 Mode (True RS-232 and TTL RS-232)
Note: To enable this mode on the acceptor, make sure the Configuration Card has been configured for "RS-
232" mode. In this mode, the user has a choice of True RS-232 levels or TTL levels.
TTL (5 VDC) levels are available in the 120 VAC model, 24 VAC and 12 VDC model of the Apex bill
acceptor. Order our Acceptor I/O Harness, Generic (P/N 05AA0002). With this cable, you must manually
connect the wires to your machine.
True RS-232 levels are available only in the 12 VDC Model of the Apex bill acceptor. In the 12 VDC
version, the harness has a DB-9 connector and hard drive connector installed to ease customer installation.
Order RS-232 Communication Harness (P/N 05AA0009) to have this ability if you use RS-232. If you use
USB, order USB Communication Harness( P/N 05AA0023).
This RS-232 mode uses a three wire interface. This interface uses a Transmit Line (TXD), a Receive Line
(RXD) and DC ground (Gnd).
This RS-232 Interface is compatible with the interface used on Mars™ GL5™ style acceptors. It is a polled
interface where the host machine is the Master and the bill acceptor is the Slave
