Certified connection and configuration of a scale (RS232)

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

In this chapter you’ll find information about configuring a scale and its authenticated connection via cable to the touch cash register. The scale and cash register have to be properly configured before being connected and used. The process is valid for scales with an RS232/USB interface using a communication protocol ECR Type#12.



Certified scale connection is a paid service and the scale and cash register connection must be sealed by a technician. After the above steps, it is therefore necessary to contact the manufacturer of the scale (which in the case of Dotypos s.r.o. scales is LESAK s.r.o.) at 775 873 570 (primary in the Czech language) and arrange a visit of a technician who will perform the sealing. You will also be able to obtain information on the fee for this service by calling the above-mentioned telephone number. Dotypos company does not verify the connection of the scale or intervene with the customer.

If you do not have a scale from Dotypos, please contact your scale supplier or dealer directly for a certified connection.

The maximum unit or total price (quantity x unit price) of the weighted item is CZK / EUR 9,999.99. Sales above this amount are not possible in certified (Welmec) mode.
