Setting the Scale Specifications for Communication to a PC

The DC-782’s RS-232C port can be used to connect the scale to a PC and output the data string to the computer. 

The following specifications must be set for the data transfer to take place:  (for more information on setting 

specifications, see Section 3.2.1)

•

SPEC05, Bit 0 Transmission Condition of RS-232C sets whether you want the data output only 

when the weight is stable or to be output unconditionally.

•

SPEC06, Bit 3 RTS/CTS Handshaking of RS-232C must be set to 0: On or 1: Off depending on the 

application receiving the data.

•

SPEC06, Bits 0, 1 and 2-Baud Rate of RS-232C must be set for the proper Baud Rate for your 

application.

•

SPC07, Bit 3-Stop Bit of RS-232C must be set to the proper Stop Bit for your application.

•

SPC07, Bit 2-Data Length of RS-232C must be set to the proper Data Length for your application.

•

SPC07, Bits 1 and 0-Parity of RS-232C must be set to the proper Parity for your application.

•

SPEC08, Bits 3 and 2 - Interval of Time Out Error of RS-232C must be set to the proper Time Out 

Interval for your application.

•

SPEC08, Bit 1 - Additional Parity Code in Text of RS-232C must be set to determine whether or not 

to allow an additional parity code in the text of the transmission.

•

SPEC08, Bit 0 - Status and Weight Condition Flag in Text of RS-232C determines whether or not the 

condition flag will be included in the transmission.
