You may need to use an external power supply to operate peripheral devic-
es.
 
Connecting a second weighing platform:
A second weighing platform can be connected to the Combics 2 at COM1, 
UniCOM or COM-WP. 
COM1  is operated in the RS-232 mode. A second weighing platform can 
use the following operating modes:
–  SBI standard
–  SBI verifi able
–  XBPI-232 (factory setting)
–  ADC-232
UniCOM can operated in either RS-232 or RS-485 mode. A second weighing 
platform can use the following operating modes:
–  SBI (RS-232 mode)
–  XBPI-232 (RS-232 mode)
–  ADC-232 (RS-232 mode)
–  IS-485 (RS-485 mode, XBPI mode, factory setting)
–  ADC-485 (RS-485 mode)
