RS-232C Specifications

The QB Series may be equipped with an optional RS-232C feature (PN 42174), which is compatible for
communication with printers and computers. When the balance is connected directly to a printer, displayed data
can be output either via the

key on the balance, or automatically when certain conditions have been met. Refer

to Table 4-1 on page 15 for a list of parameters available.

NOTE: The optional battery pack (PN 42169) cannot be used simultaneously with the RS-232C option.
