4.3.3 Wiring Diagram

The diagram illustrates the connection of the cashless vending unit to the Modbus IO board and multiple dryers, including power supply, communication lines, and relay control signals.

4.3.4 Vending Machine, IO Board, and Dryers

The Vending Unit (VU) provides power and RS485 communication to the IO Board. The IO Board then distributes relay start signals and feedback inputs to one to four dryer machines.

VU to IO Board

VU Wire	Color	IO Board Terminal	Signal
+12/24 VDC	Red	J1	Power supply
GND	Black	J1	Power ground
RS485 A+	Yellow	J5	RS485 A+
RS485 B-	White	J5	RS485 B-

IO Board to Dryer 1

IO Board Terminal	Wire Color	Dryer Connection	Signal
J6 / NO1	Red	Start input	Relay start pulse
J6 / COM1	Black	Common	Relay common
J3 / IN1	Yellow	Busy feedback	Dryer busy signal
J4 / GND_IN	White	Feedback ground	Feedback reference

IO Board to Dryer 2

IO Board Terminal	Wire Color	Dryer Connection	Signal
J7 / NO2	Red	Start input	Relay start pulse
J7 / COM2	Black	Common	Relay common
J3 / IN2	Yellow	Busy feedback	Dryer busy signal
J4 / GND_IN	White	Feedback ground	Feedback reference

IO Board to Dryer 3

IO Board Terminal	Wire Color	Dryer Connection	Signal
J8 / NO3	Red	Start input	Relay start pulse
J8 / COM3	Black	Common	Relay common
J4 / IN3	Yellow	Busy feedback	Dryer busy signal

Notes

Red and black wires carry the start pulse from the relay.
Yellow and white wires carry the busy feedback from the dryer.
The “busy” signal from the Dryer is a positive voltage pulse ranging from +12 VDC to +24 VDC between GND_IN and the corresponding IN1–IN4.
One IO Board supports up to four dryer machines when wired according to the available relay and input channels.
Keep cable runs short.

4.3.5 Wash Machines RS485 Bus

The Wash Machines RS485 Bus connects the Vending Machine to the washing machines through an external RS485 adapter and RJ45 cabling.

Laundry Machine Connection Socket (RJ45 / Modbus)

This socket is a communication interface used to connect washing machines and dryers to the central control system (Vending Unit) via Modbus RTU using an RJ45 connector.

The socket is based on a standard module with terminal blocks and T568A/B color coding, simplifying connection of twisted pair cables (CAT5/CAT6).

Notes

Use a flat CAT5 patch cable between the RJ45 outlet and the first machine.
Keep the cable run between 2 and 5 meters.
Each next washing machine is connected through the RJ45 Y-connector of the previous machine.
Maintain the bus chain order exactly as shown to avoid communication issues.

5. Maintenance

Regular maintenance of the MX2150 Vending Machine is essential to ensure reliable operation, long service life, and high-quality user experience.

Maintenance tasks include periodic inspection of internal components, cleaning of external surfaces, and timely replacement of consumables such as receipt paper. All maintenance procedures must be performed with the device powered off unless explicitly stated otherwise.

5.1 Receipt Printer Paper Replacement

The device is equipped with an integrated thermal receipt printer that uses standard 80 mm thermal paper rolls. Thermal paper changes color when heated, enabling printing without ink.

Procedure

Open the printer compartment
- Unlock and open the front service door of the unit
- Locate the printer module and open the printer cover
Remove the used paper roll
- Take out the empty or remaining paper roll
- Remove any paper residues from the feed mechanism
Prepare a new paper roll
- Use only 80 mm thermal paper rolls
- Remove the outer adhesive layer of the roll
Insert the new paper roll
- Place the roll into the holder
- Ensure the paper feeds from the bottom towards the front (correct orientation is critical)
Feed the paper
- Pull out a short length of paper
- Align it with the paper guide and print head
Close the printer cover
- Close firmly until it clicks into place
Test the printer
- Power on the device
- Use the feed function or perform a test print

Important Notes

Incorrect paper orientation will result in no printing.
Replace the roll when a colored indicator stripe appears on the paper.
Do not use damaged or low-quality paper rolls.
Avoid touching the thermal surface of the paper.

Proper paper installation ensures consistent print quality and prevents printer malfunctions.
