FUNCTIONS G-18.mft with vending machine control system "Battery empty" detection The light-emitting diode on the left-hand side of the coin validator indicates the voltage state of the battery when the return lever is pressed following the insertion of a coin (see section "Displaying battery voltage" in Chap. 8 "Maintenance and service"). Inhibiting of specific coin types If specific coin types are no longer to be accepted for payment at the vending machine (e.g. because there are too many false coins of a specific coin type in circulation), these coin types can be inhibited using the switching blocks on the rear of the coin validator (see section "Inhibiting coins" in Chap. 7 "Operation"). Teach mode (optional) The coin validator provides six memory locations (coin channels) for configuring a maximum number of six new coins/tokens, which means that coin/token measured values can be re-assigned directly on the vending machine by inserting the respective coins/tokens. The acceptance band generated then accepts these tokens as payment in the vending machine. (See section "Teaching coin channels in teach mode" in Chap. 7 "Operation") Communication with MDB periphery (optional) If the coin validator is supposed to control external devices using the MDB protocol, an NRI card reader and NRI display can be connected using the 10-pole MDB interface on the rear of the device and using an MDB cable set (see section "Accessories" in Chap. 10 "Technical data"). 26 National Rejectors, Inc.

G-18.mft with vending machine control system STARTING UP 6 Starting up The G-18.mft is either • started up in a vending machine, or • connected to one of the two NRI software solutions used to configure the device: – PC programming station (WinEMP) – Palm handheld (PalmEMP) Starting up in the vending machine To start up the device you must: • Fasten and connect the coin validator and additional control PCB in the vending machine • Activate a test run of the vending machine components to be controlled • Set prices • Select "exact price" or "overpay" Install coin validator and additional control PCB 1 Interrupt the voltage supply of the vending machine. 2 Set DIL switch 9 of the lower switching block S3 to the lower position (OFF). The MDB protocol for the vending machine control system has been selected. 3 Set DIL switch 8 of the middle switching block S2 also to the lower position (OFF). Master operation for any connected slaves has been selected. 4 Connect both enclosed ribbon cables to the 14-pole and 6-pole interfaces (3 and 4, Fig. 2a) of the coin validator. National Rejectors, Inc. GmbH, Buxtehude If MDB slave devices are to be connected to the coin validator, connect the MDB cable set to the 10-pole MDB interface 2 of the coin validator (see Fig. 2a). 5 Hang the coin validator in the vending machine mount using the lateral mounting studs 1 (see Fig. 2a). 27

FUNCTIONS G-<strong>18.mft</strong> with vending machine control system<br />
"Battery empty" detection<br />
The light-emitting diode on <strong>the</strong> left-hand side <strong>of</strong> <strong>the</strong> coin validator indicates<br />
<strong>the</strong> voltage state <strong>of</strong> <strong>the</strong> battery when <strong>the</strong> return lever is pressed following <strong>the</strong><br />
insertion <strong>of</strong> a coin (see section "Displaying battery voltage" in Chap. 8<br />
"Maintenance and service").<br />
Inhibiting <strong>of</strong> specific coin types<br />
If specific coin types are no longer to be accepted for payment at <strong>the</strong> vending<br />
machine (e.g. because <strong>the</strong>re are too many false coins <strong>of</strong> a specific coin type<br />
in circulation), <strong>the</strong>se coin types can be inhibited using <strong>the</strong> switching blocks<br />
on <strong>the</strong> rear <strong>of</strong> <strong>the</strong> coin validator (see section "Inhibiting coins" in Chap. 7<br />

Teach mode (optional)<br />
The coin validator provides six memory locations (coin channels) for<br />
configuring a maximum number <strong>of</strong> six new coins/tokens, which means that<br />
coin/token measured values can be re-assigned directly on <strong>the</strong> vending<br />
machine by inserting <strong>the</strong> respective coins/tokens. The acceptance band<br />

If <strong>the</strong> coin validator is supposed to control external devices using <strong>the</strong> MDB<br />
protocol, an <strong>NRI</strong> card reader and <strong>NRI</strong> display can be connected using <strong>the</strong><br />
10-pole MDB interface on <strong>the</strong> rear <strong>of</strong> <strong>the</strong> device and using an MDB cable set<br />
