RS-232 Interface:
Note:
Scientech balances are DTE (computer) devices. If communicating to another DTE device (ie
computer), a Scientech RS-232 cable, PN11897, or normal null modem cable is required. If you
are communicating to a DCE device (printer), a serial cable is required. Scientech offers a serial
cable, PN11367, for your convenience.
Your balance is equipped with a bi-directional RS-232 compatible inter-
face. The RS-232 connector is a 9 pin D subminiature connector located
on the balance rear panel. The pin out and pin descriptions are shown
here.
RS-232 Specifications:
Type
EIA-RS-232C, DTE
Method
Half-duplex, Asynchronous Transmission, Bi-directional
Format
4800, 9600 and 19,200 baud rate selectable (default is 9600)
Code: ASCII
For parity Even or Odd: Data bit 7, Stop bit 1.
For parity none:
Data bit 8, Stop bit 1.
RS-232 Front Panel Configuration:
Before using the RS-232 feature of your balance, it is necessary to configure the interface properly for your
application. The RS-232 Configuration Mode allows you to set baud rate, auto send, continuous send, send
when stable and display blanking. The balance is configured with defaults at the factory. The default modes is
9600 baud, no parity.
It is not necessary to follow the entire configuration procedure if only one parameter is to be changed. Use step
1 to enter the menu and press MODE/UNITS to scroll through the different parameters. When the desired
parameter is displayed the SEND key will scroll through the settings for that parameter. Pressing the
RANGE /FUNCTION at any time will save the settings and return to normal weighing mode.
Your terminal program and the balance must have the same baud rate and parity to work. If you choose NONE
for parity please set your terminal program to 8 data bits, 7 data bits for EVEN or ODD parity.
To enter the RS-232 configuration mode via the front panel, proceed as follows:
