Blue Whale - Installation
Example: Blue Whale Stack Dryer & Washer
(A) Connection Washer/Dryer
1. Blue Whale machine, the connection is direct and simple. You will see three wires running from the board to the coin acceptor (Black, White, and Red).”
2. As shown in the picture above, cut the Black and White wires between the board and the coin acceptor. Then, connect the input and output using the 4-core wire from the device.
3. Leave Red wire
- Do not cut Red (it’s power). It should remain continuous from board.
4. Cut the Black & White wires
- Cut both Black and White roughly in the middle of their run.
5. Two sides after the cut
-
The ends coming from the board = OUTPUT (to the machine board).
-
Board-White → OUT+
-
Board-Black → OUT−
-
-
The ends going to the coin acceptor = INPUT (from the coin acceptor).
-
Acceptor-White → IN+
-
Acceptor-Black → IN−
-
6. Power ON and test
- Insert a coin/token, If the Coin Read in Node Cloud app shows pulses and the machine credit—done.
7. If it shows “No Pulse Detected”:
-
Confirm IN/OUT are not swapped.
-
Verify + and − on both input and output pairs.
-
Ensure the coin is actually accepted (a rejected coin won’t pulse).
(B) Device Connection - ALPHA-1
1. Devices will be placed behind the machine by screwing it using a specific screw.
2. Connecting the 4-Core Wire to the Device
-
Connect the 4-core wire to the device according to the terminal markings:
-
Input (IN−, IN+)
-
Output (OUT−, OUT+)
-
-
After wiring, make a loop connection between:
-
IN− (Input negative)
-
OUT− (Output negative)
-
-
Ensure all connections are secured and insulated before powering ON.

Blue Whale Cashless Machine (Non-Coin Acceptor)
(A) Wire connection Dryer
Dryer Connector1. Locate the cashless connector
-
Identify the two output wires shown in your picture:
-
White = Output (−)
-
Green = Output (+)
-
2. Dryer cashless machines with a connector as shown in the picture above, use the output connection only. Tap into the two wires: White (Output Negative −) and Green (Output Positive +), using a 2-core cable from the device.
(B) Wire Connection Washer
Washer connector1. Locate the cashless connector
-
Identify the two output wires shown in your picture:
-
Pink = Output (−)
-
Red = Output (+)
-
2. Washer cashless machines with a connector as shown in the picture above, use the output connection only. Tap into the two wires: Pink (Output Negative −) and Red (Output Positive +), using a 2-core cable from the device.
(B) Device Connection - ALPHA-1
Quality Note: Looping From Input (-) To (+)
1. Devices will be placed behind the machine by screwing it using a specific screw.
2. Connecting the 2-Core Wire to the Device.
-
Connect the 2-core wire to the device according to the markings:
-
Output (OUT−, OUT+)
-
-
After wiring, make a loop connection between:
-
INPUT− (Input negative)
-
INPUT− (Input positive)
-
-
Ensure all connections are secured and insulated before powering ON.

Power Supply Connection for Blue Whale Machine
Quality Note: 5v Power Supply Required
1. For the Blue Whale machine, each device must have its own dedicated power supply. For example, one device requires one power supply. If there are five devices, you must use five separate power supply connections, as shown in the image above.
