RS-232 Connection
The DC-200/300 scale output can be sent to and captured by the HyperTerminal program in Microsoft Windows.
This connection can also be used to test whether the scale is outputting correctly. To use the following procedure,
you must connect one of the scale’s RS-232C port and one of the computer’s COM ports.
6.2.1
Spec Settings for RS-232C Connection to a PC
The customer specifications on the scale must be set to tell the DC-200/300 which of its three RS-232C ports
(main, SIO1 or SIO2) you want the output to the PC to be sent through.
If the printer is connected to the main port (next to the keyboard port), the settings should be as follows:
•
SPEC 15: SIO SELECT JOB to “2: PC”
•
SPEC 16: BAUD RATES (SIO) to the proper baud rate for your application
•
SPEC 17: DATA LENGTH (SIO) to the proper length for your application
•
SPEC 18: PARITY BIT (SIO) to the proper setting for your application
•
SPEC 19: STOP BIT (SIO) to the proper setting for your application
If the PC is connected to one of the option ports, the spec settings depend upon what else you have connected to
the other port. These two RS-232C ports are set in tandem using SPEC 20: RS232 OPTION CARD. Possible
combinations include the following:
If connecting to
