As a printer-driven cash drawer, it requires a wired connection to the receipt printer, enabling the POS system to automatically open it. Keep this in mind when setting up your connections. --- ### Hardware setup || Note: It is crucial to connect each side of the cable to the correct device. The ends of the cable differ, so directionality is important. As stated earlier, this cash drawer operates via a connection to a receipt printer. Pay attention to which end of the cable links to each device. The cable is clearly labelled on both sides to indicate compatibility with the respective device. ![](https://storage.crisp.chat/users/helpdesk/website/74260be74e639800/cash-drawer-cable_3jimfb.png) **Step 1:** Locate the **RJ-12 (phone jack) port** at the bottom rear of the receipt printer among the ports and connections. It might be offset from other ports and is typically marked with a cash drawer symbol or "drawer-kick" label. Connect the designated printer end of the cable to this port. ![](https://storage.crisp.chat/users/helpdesk/website/74260be74e639800/32820576x260_18mxuap.png) **Step 2:** Attach the other end of the cable to your Cash Drawer.
