There are two common methods for using a cash box in a retail or point-of-sale (POS) setup. Here's a detailed explanation of both approaches:
1. The first method involves connecting the cash box to a receipt printer, which is then linked to the computer. In this configuration, the cash drawer receives power from the printer. However, it's important to note that the 58mm receipt printer typically operates at 12V, while the cash drawer sensor requires 24V to function properly. This voltage mismatch means that the 58mm printer cannot trigger the cash drawer to open. On the other hand, an 80mm receipt printer usually runs on 24V, which is compatible with the cash drawer’s requirements, allowing it to open correctly when needed.
2. The second approach involves connecting the cash box directly to a cash box drive box, which is then connected to the computer. In this case, the cash box draws power from the computer, which generally provides 5V. To make this work, the cash box drive box contains an internal transformer that converts the 5V input into 24V, which is necessary to operate the cash drawer. This setup ensures compatibility and reliable performance even when the computer’s output voltage is lower than what the drawer requires.
Both methods offer practical solutions depending on the available hardware and system configuration. Whether you're using a receipt printer directly or a drive box, understanding the voltage requirements is essential to ensure the cash drawer functions as intended. If you're setting up a new system or troubleshooting an existing one, checking the voltage specifications of all components will help avoid potential issues.
