Cable:<br />
- The weighing module is provided with a UART serial interface and a USB interface. The cable<br />
length is limited to:<br />
- 0,3 m for the UART serial interface (not shielded);<br />
- 5,0 m for the USB interface (shielded).<br />

Power supply: 5,0 V DC ± 5%<br />
Power supply current: 200 mA.<br />
1.3 Essential shapes<br />
The weighing module is built according to drawings:<br />
- “Outline drawing 603”, drawing number 7978/0-02;<br />
- “Exploded view 603”, drawing number 7978/0-03;<br />
- “Cross-sectional drawing 603”, drawing number 7978/0-04;<br />
- “Outline drawing 8002”, drawing number 7978/0-05;<br />
- “Exploded view 8002”, drawing number 7978/0-06;<br />
- “Cross-sectional drawing 8002”, drawing number 7978/0-07;<br />
- “Outline drawing 35001”, drawing number 7978/0-08;<br />
- “Exploded view 35001”, drawing number 7978/0-09;<br />
- “Cross-sectional drawing 35001”, drawing number 7978/0-10;<br />
- “Platform dimensions”, drawing number 7978/0-15.<br />
The maximum platform dimensions are described in drawing “Platform dimensions”, drawing<br />
7978/0-15.<br />
The data plate is secured against removal by sealing or will be destroyed when removed. The data<br />
plate mentions at least the information and markings as described in the OIML R60 and R76<br />
documents. In the countries where it is mandatory the load cell should bear this test <strong>certificate</strong><br />
number: TC7978.<br />
Securing:<br />
The sealing shall be described in the approval <strong>certificate</strong>.<br />
Both loadcell board and Digicell board MFR can be identified by unique ID numbers stored<br />
permanently on the particular EEPROM. These numbers cannot be erased or changed. Any exchange<br />
of the boards can be identified by reading these numbers.<br />
