6. Communication with the scale
The communication of the scale with external devices (e.g. cash register, computer) is effected via
the PC connector. This is a serial, RS232C type interface. Description of the connector pins is
presented in the Section 2.5.
Communication with scale treated as NAVI (Non Automatic Weighting Instrument) in terms of
WELMEC (European cooperation in legal metrology) is possible in terms of modular approach.
Modular Approach
The "open" modular approach used to allow the possibility of connecting a POS with a TC (Test
Certificate) to a weighing instrument having a TAC (Test Approval Certificate) with a general
statement concerning the connection of any POS with a TC.
When the "open" modular approach is used the following requirements are valid for the
connection of a POS to a NAWI.
A POS device may be connected to a NAWI which meets the following requirements:
1. The connection is possible only with NAWIs intended for direct sales to the public.
2. The connection is possible only through the NAWI's protected interfaces.
3. The NAWI shall transmit data relating to primary indications only in such a manner that
the POS can meet the requirements.
4. The connection to the POS shall not allow the metrological functions of the NAWI to be
inadmissibly influenced by the POS.
5. The connection of the POS shall not lead to an instrument having other essential
characteristics (e.g. metrological) than those specified in the TAC for the instrument.
6. Examination: of NAWI: compatibility of preset tare coming from the POS and preset tare
coming from the instrument and tare device of the instrument.
Note: 2 to 5 above to be declared by the manufacturer.
