Navigation:  Cash register preparation > Connecting peripherals > Connecting scale >

This chapter has general information about how to configure a scale and connect it via cable to the 14" and 15" touch cash register. The cash register has to be properly configured prior to being connected and used. The process is valid for scales with an RS232 interface using the CAS communication protocol.


Before you connect

1.Remember to remove the arresting screw from the bottom of the scale that is attached to its body and prevents it from becoming damaged.

2.Connect the scale via the enclosed power supply.

Connecting to the touch cash register

1.In the Dotypos Marketplace application download and install the Scale driver (Ovladač váhy).

2.Connect the scale with the touch cash register via the enclosed USB to RS232 and NULL MODEM cables.



Always connect the USB to RS232 cable to the enclosed NULL MODEM. Otherwise the weighing machine’s electronic parts could be permanently damaged!




Sometimes the scale has to be connected to the touch cash register via a powered USB switch. In this case, the MODEM NULL cable is connected to the USB switch and the USB switch is then connected to the touch cash register’s USB port. You should receive an appropriate USB switch along with the touch cash register.



Driver settings

1. Install the Scale Driver app through the Dotypos Marketplace.

2.Run the scale application Scale Driver settings from the touch cash register desktop.
