the relay contacts (Pin 7 and 8 on the 9-pin connector). Without the 120 VAC power supply, the output is
on the 18-pin connector and is a normally high, open-collector transistor output.
Low Level Pulse Mode- Connections:
Power
120 VAC Model- Connect 120 VAC power to Pins 4 (Black wire) and 6 (White wire) on the 9-pin connector
(see Figure 1).
24VAC Model- Connect 24 VAC power to Pins 5 (Black wire) and 6 (White wire) on the 9-pin connector
(see Figure 1).
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.
Inputs (0-5 VDC Operation Only)
Pin 12 (Violet wire) on the 18-pin connector- Accept Enable line. Bring low to enable the acceptor. (Tie to
DC ground, Pin 4 (Black wire) on the 18-pin connector to always enable the acceptor.)
Pin 3 (Yellow wire) on the 18-pin connector- Serial/~Pulse Line. Pull low (connect to Pin 4 (Black wire),
which is DC Ground) to enable the Pulse Mode of operation. Note: You do not need make this connection
if you have selected “Pulse/Serial” on the Configuration Card and you have specified some number for the
Pulses Per Dollar. By selecting some number for Pulses Per Dollar, you have told the acceptor that you are
in Pulse Mode, not Mars Serial Mode. This eliminates the need for this connection, commonly called a
“Pulse Jumper Plug”.
Outputs
120 VAC or 24 VAC Model- You can use the relay output on Pins 7 (Brown wire) and 8 (Blue wire) 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.).
In addition, the 120 VAC model, 24 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. (5-12VDC 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.
Serial Mode- (Works with 12 VDC, 120 VAC and 24 VAC models of the Apex Bill Acceptor.)
This Interface is Mars compatible. This interface is a non-isolated interface. (TTL/CMOS compatible.) This
interface operates at 600 baud, 1 start bit, 1 stop bit and 8 data bits. The Apex bill acceptor will pull the
Interrupt line low when it has a serial message to send to the host. The host machine will pull the Send line
low when it can receive this serial message. The Apex will then output a Credit Message if the bill is
recognized. A Reject Message is sent if the bill is not recognized. After the Credit message is sent to the
host, the Enable line is to be pulsed high within 5 msec if the host wants to return the bill to the customer. If
the Enable Line remains low, the acceptor will accept the bill and send a Vend Message to the host. The
Host machine can tell the acceptor to resend any particular message by bringing the Send Line high and
pulse it low within 2-4 msec.
Serial Mode- Connections
120 VAC Model- Connect 120 VAC power to Pins 4 (Black wire) and 6 (White wire) on the 9-pin
connector (see Figure 1).
24VAC Model- Connect 24 VAC power to Pins 5 (Black wire) and 6 (White wire) on the 9-pin
connector (see Figure 1).
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.
