The ad you ordered from will soon be canceled (after being out of stock, which ebay won't let me restore anymore) due to new laws in the EU, so the ability to order here will be canceled and it is no longer possible to change it.
Therefore, in the future, I recommend watching the video in which you will find out (in the video header) where you can find me after canceling the ad.

Fluid resistance:
As part of the overhaul, the PCB (printed circuit board) was dismantled and sprayed with a special insulating varnish resistant to aggressive liquids, which prevents damage to the PCB by oxidation after the ingress of unknown liquids and ensures a long-term increase in reliability and service life of the validator in humid environments.

Since I found out that most people interested in buying a validator do not have a clear idea of ​​what type of validator they need as a replacement for their own defective piece or for building own project, so I'll specify.
G-13mft is a model family, which is produced in many variants differing from each other in the way of communication with the master-superior machine (vending machine, slot machine, etc.).
So there are variants with communication type:
- 6 channel parallel casino type for slot machines, pinballs, washing machines etc... (this is a variant I offer in the ad)
- 6 channel parallel for vending machine - uses a solenoid of a different type and the routing of bad and good coins is oriented the other way in compared with the casino type, however converting a casino type to a vending type and vice versa is possible.
- RS232 / UART of both versions (casino and vending)
- USB of both versions (casino and vending)
- CCTALK of both versions (casino and vending)

So before ordering, I recommend sending photos of your type that you want to replace to assess whether it is compatible with my offer and what are the type converting and programming options.

In addition to the variants of vending and casino and different types of communication, we must distinguish the method of programming specifics of the communications and currency type.

The validators that I offer (Casino-6 parallel channels) can be programmed for any coin, but that's not all you need to know for validator to work properly for you.

It is about:
- supply voltage level, default is 10 - 16V DC
- number of pulses per channel (1 or more), default settings is one pulse.
- pulse length (miliseconds), default settings is 100miliseconds (0,1 second)
- the type of currency and which coins are assigned to which channel 1 to 6. Default is € currency in the following order:
Channel 1 = PIN 7 of the validator connector = 1 pulse 0.1 seconds lenght if a 0,05 € coin is received.
Channel 2 = PIN 8 of the validator connector = 1 pulse 0.1 seconds lenght if a 0,10 € coin is received
Channel 3 = PIN 9 of the validator connector = 1 pulse 0.1 seconds lenght if a 0,20 € coin is received
Channel 4 = PIN 10 of the validator connector = 1 pulse 0.1 seconds lenght if a 0,50 € coin is received
Channel 5 = PIN 3 of the validator connector = 1 pulse 0.1 seconds lenght if a 1 € coin is received
Channel 6 = PIN 4 of the validator connector = 1 pulse 0.1 seconds lenght if a 2 € coin is received

So if you want other currency, or combination two or three different currencies, or metal token programming, or any memorial coin and also you want other settings of channels, change lenght of pulses or change number of pulses of each channel or channel combination, please contact me.
I need to know what you want, because telepathic transmission is not my strong point :)
It's not easy, is it?

But I'll make it easier for you ...

If you can't find the mentioned parameters but you have an old validator that you want to replace, or have more pieces of the same, contact me and add photos of what you have.

If you don't have the time or appetite for these things, you can order a simple tester, which is shown in the third photo from the end and in the second photo from the end of this ad.
It is homemade, but it fulfills its purpose, and as soon as you connect the tester to your validator and start inserting valid coins, you will see the green LEDs flashing (if your validator working properly and is compatible with parallel 6 channel casino or parallel 6 channel vending type from NRI or also of course from other manufacturers).
If you make a video (link to download of video) of this work and send it to me, I will know how to program the validator for you.
You can order a simple tester including a power supply here:

If you need to program NRI G series validators yourself, you can purchase the device for this purpose here: https://www.ebay.com/itm/174431539976

Text on the technical specifications of the offered validator and the method of refurbishment:
I offer an electronic coin validator type G-13mft with six parallel outputs OPEN COLLECTOR  (OC) type and one output OC for next one optional sorting solenoid for heading coins in the third direction.
The coin validator is from the NRI brand and is controlled by own MCU chip build in validator.
Each coin validator is completely refurbished, thoroughly tested and cleaned.

The price of this validator is with programming of custom channel configuration (or with the original data blocks originally programmed coins from factory) by order requirment and agrement.

If you are interested in programming according to your own requirements, it is necessary to state which coins use, number of pulses, pulse lengths of each output and which outputs is used according to the value and currency type of a suitable coins or tokens.

The input of coin validator (pin 6) is to locking the reading of coins in case the master machine (vending machine/slot machine etc) is not ready to receive signals coins so in this situation is input pin 6 in state "HIGH" (3,5 to max.35 volts or open) and if machine is ready, then send permanent signal "LOW" (connect pin 6 via 1k5 resistor or simmilar to GND).
The power supply of coin validator is 10 to 16 volts DC or 10 to 27 volts DC on pin 2 and GND on pin 1 by order requirment and agrement.

It is also possible to specially program a binary combination of output channels or add external solenoid outputs to sort the direction of received coins at the expense of the number of output channels, so it is possible to program up to 4 signals for  four pieces of sorting solenoids (up to for 5 cash boxes) and at the same time three of output channels for up to 7 credit sizes by binary combination.

I have practical experience with repairing, diagnosing and programming any defects of G-13mft coins validator since 2007, so thousands of pieces have already passed through my hands.
During this work, I successfully and reliably removed all defects without complaint.


Wiring, dimensions and other technical parameters are in the pictures including schematics of simply tester.

Example of changing settings:
- blocking of € 0.50 and € 2.00 coins
- change of output channels of € 1, € 0.10 and € 0.20 coins
- instead of one pulse to send 10 pulses
- pulse length from the original 100mS to 300mS.

A simple solution.
The validator is placed on a box with a hole so that it is in a vertical position and the coins fall freely ...
