How to connect cash drawer to computer?

Connecting a cash drawer to a computer usually involves two aspects: hardware connection and software configuration. The following are the general steps of the connection process, but please take notice that cash drawers of different brands and models may vary, so it is best to refer to the user manual of the cash drawer and POS system you are using for operation.

一、 Preparation work

1. Confirm the cash drawer model and interface:

Check the model and interface type of the cash drawer (such as USB, RJ11, MuItiPRO® Etc.)

Confirm if the computer has the corresponding interface or if an adapter is required.

2. Prepare the connecting cable:

Prepare the corresponding connecting wires according to the interface type of the cash drawer.

If the connecting cable is not provided with the cash drawer, a suitable connecting cable needs to be purchased.

二、 Connection steps

1. Connect the interface cable:

For cash drawers with MultiplaRO® ports, connect one end of the POS printer interface cable to the MultiplaRO® located below or on the back of the cash drawer Interface, connect the other end to the printer interface of the computer (if the computer does not have a printer interface, an adapter or adapter may be needed).

For a cash drawer with a USB interface, connect one end of the USB interface cable to the USB interface at the bottom of the cash drawer and the other end to the USB interface of the computer.

If the cash drawer uses other types of interfaces (such as RJ11), it needs to be connected to the computer's serial port using the corresponding cable (which may require the use of a serial to USB adapter).

2. Install the driver program:

If your cash drawer requires a specific driver, make sure to download and install the latest version of the driver from the manufacturer's official website. In most cases, USB interface devices are plug and play and do not require additional driver installation.

After the driver installation is completed, the computer will be able to recognize and communicate with the cash drawer.

3. Configure software:

Open the POS (Point of Sale) software or cash register software you are using, and go to the settings options to find the peripherals or hardware configuration section. Here, you need to specify the type of cash drawer, connection method (such as COM port or USB port), and other necessary parameters (such as baud rate, data bits, etc.).

Ensure that the software can correctly control the opening and closing of the cash drawer.

三、 Testing and Validation

1. Open the cash drawer:

Send the command to open the cash drawer in the software

Observe whether the cash drawer can be opened normally.

2. Close the cash drawer:

Send a command to close the cash drawer in the software (if the software supports this feature).

Observe if the cash drawer can be closed properly.

3. Check the stability of the connection:

Perform multiple opening and closing operations to check if the connection is stable and reliable.

If you find that the connection is unstable or not working properly, please check if the connection cable, driver program, and software settings are correct.

四、 Precautions

1.Voltage requirements:

Some cash drawers (such as HP cash drawers) only support specific voltages (such as 24 volts). When connecting, please ensure that the voltage meets the requirements to avoid damaging the cash drawer or computer.

2. Security:

When using cash drawers, please ensure that the security lock and key system are installed correctly to improve security and avoid losing or handing over keys to unauthorized personnel for use.

3. Maintenance and upkeep:

Regularly clean and maintain cash drawers to ensure their proper functioning and extend their lifespan. If any malfunction or damage is found in the cash drawer, please contact the after-sales service personnel for repair or replacement in a timely manner.

To summarize, connecting a cash drawer to a computer requires following certain steps and precautions. By proper connection and configuration, the computer can control and operate the cash drawer, and it can be used normally in the POS system.
