National Rejectors, Inc. GmbH, Buxtehude

Interfaces (on coin validator)

On the rear of the coin validator there is a 6-pole 

and a 14-pole 

6

 interface

to the additional control PCB (to the vending machine). At the bottom of the
device there is a connecting plug 

10

 for the PC programming station or the

Palm handheld. Peripheral devices, such as a display or card reader, can
be connected to the 10-pole MDB interface 

5

. (See Fig. 1a)

Interfaces 

8

/

– additional control PCB (6-/14-pole)

These two interfaces are used to connect the coin validator to the additional
control PCB to which the vending machine components such as the battery,
escrow,  selection  buttons,  pilot  lights,  product  ejectors,  and  return
mechanism are connected (see section "The additional control PCB" in this
chapter).

Interface 

– MDB periphery (10-pole)

If the G-18.mft is operated as a 1-5-chute vending machine control system,
use an MDB cable set to connect all slave devices, such as an MDB card
reader  and  MDB  display  to  this  interface  (see  section  "Accessories"  in
Chap. 10 "Technical data").

For further information on the MDB interface, please refer to "NAMA
document MDB/ICP, 2.0" (www.vending.org).
For details regarding pin assignment, see section "Pin assignment
and connection diagrams" in Chap. 10 "Technical data".

Pin 7 of this interface has been assigned to a wake-up line. The coin validator
itself is woken up from an energy-saving standby mode by the insertion of
a coin and then wakes up all connected slave devices via the wake-up line.
The coin validator is now in its active state and keeps the wake-up line on
"low" = active (all devices ready for operation) until the inserted coin has
been processed.

Interface 

10 

– configuration (WinEMP/PalmEMP)

To configure the coin validator the device is connected to a PC or a mobile
Palm handheld. For that purpose, the G-18.mft is equipped at the bottom
with  a  PCB  direct  plug  (see  Fig. 1a),  which  is  used  to  connect  the  coin
validator to the PC programming station or to a Palm handheld. The device
can  then  be  set  up  using  the  configuration  and  diagnostics  software
"WinEMP" or "PalmEMP" (see Chap. 6 "Starting up" and Chap. 9 "Which
functions can be set using WinEMP/PalmEMP?").

For details regarding pin assignment, see section "Pin assignment
and connection diagrams" in Chap. 10 "Technical data".
