How to Connect a Cash Drawer to Your Qashier POS

Connect a cash drawer to your Qashier POS so it pops open automatically when you accept a cash payment. This guide covers the QashierX2, QashierXL Slim and QashierXS, drawers connected through an external receipt printer, and the older QashierX1 and original QashierXL.

Applies to: Singapore, Malaysia, Philippines, Thailand · Qashier POS · Turning on automatic opening needs a QashierHQ login. Opening the drawer manually on the POS needs the Terminal PIN.

Before you start

  • A cash drawer and its cable. Drawers supplied for the QashierX2 and the original QashierXL use an RJ11 (telephone-style) cable. The older QashierX1 drawer uses a micro USB cable.

  • For the QashierX2: the Expansion Hub and the Docking Station. The drawer does not plug into the X2 body.

  • Your QashierHQ login, to turn on automatic opening.

Step 1: Turn on automatic opening in QashierHQ

The drawer opens on cash payments only when this setting is ticked. It is off by default.

  1. Log in to QashierHQ and go to Settings > Additional Settings.

  2. Under POS Settings, tick Automatically open cash drawer when you accept a cash payment. The change saves on its own.

  3. Give the POS a few minutes to pick up the new setting. If the drawer still does not open on a cash sale, restart the Qashier POS app.

Step 2: Connect the drawer to your terminal

Follow the section for your model.

QashierX2

  1. Connect the Expansion Hub to the Docking Station.

  2. Plug the cash drawer's RJ11 cable into the cash drawer port on the Expansion Hub.

  3. Dock the QashierX2 on the Docking Station.

For the rest of the X2 setup, including charging through the dock, see QashierX2 POS Setup: Unboxing, Charging, Receipt Roll and Connections.

QashierXL Slim

  1. Plug the cash drawer cable into the cash drawer port on the QashierXL Slim.

  2. Power on the XL Slim and test the drawer (see below).

If you are not sure which port is the cash drawer port, contact support before forcing the plug in.

QashierXS

Whether a cash drawer comes with the QashierXS depends on your market and bundle. Before you connect a drawer to an XS, check with support which cable and port to use. For the XS itself, see QashierXS Setup: Unbox, Power On, Load Receipt Paper and Charge.

Using an external receipt printer?

If your main receipt prints from an additional printer instead of the terminal, the POS sends the open-drawer signal through that printer. The drawer must be plugged into the printer, not the terminal.

  1. In QashierHQ, go to Settings > Printer Settings > Receipt/Order Chit Settings.

  2. If Enable Additional Printer to print main receipt is ticked, plug the cash drawer's RJ11 cable into the cash drawer port on that receipt printer.

Older models

QashierX1 (existing X1 users, and merchants in Thailand): the X1 drawer uses a micro USB cable. Plug it into the micro USB port next to the power button on the X1.

QashierXL (original model): the drawer uses a telephone-style (RJ11) cable. Plug it into the cash drawer port on the back panel of the XL. The photos below show the original XL, not the XL Slim.

Test your drawer

  1. On the POS, open Cash Management.

  2. Tap the cash drawer icon and enter your Terminal PIN if asked. The icon only appears once the setting from Step 1 has reached the POS.

  3. The drawer should open. If you see Cash drawer not connected, go to the next section.

You can also make a test sale and pay in cash. The drawer opens when the payment is accepted.
