How to Use Cash Drawer

Mercy Zhang OCOM Originals 2014-09-26 16:27:57
There are two ways to use cash drawer:
1. Cash drawer connects to receipt printer, receipt printer connects to PC. In this way, cash drawer gets power from receipt printer directly. Since 58mm receipt printer power is 12V, cash drawer sensor is 24V. So 58mm receipt printer can't open cash drawer. But 80mm printer is 24V, no problem to open cash drawer.

2. Cash drawer connects to USB trigger. USB trigger connects to PC. Cash drawer gets power from PC. PC is 5V output. But USB trigger has a transformer in it which can transfer 5V to 24V. Therefore can drive cash drawer.
