6) When open, select the Set Up menu then "Communications" command to
open the serial port setup sub-window and to initialize the serial port.
7) Make the following selections in the serial port sub-window:
COM Port - Select the COM port (1 or 2) at which serial port the meter's
serial cable is physically connected. If an error message is received that the
"Selected Serial Port is currently in use" select another port. This may
require changing the serial cable connection at the PC to match your
change. If no serial port is available, you may have to disconnect a serial
device (i.e. mouse or printer), disable its software and re-boot the PC to
make a serial port available.
Baud Rate - 2400. The Model 235 uses a fixed output rate which can not be
changed
Data Bits - 7
Start/Stop Bits - 1
Parity - None or Odd
Flow Control - Hardware
1)
Gateway 2000 and Compac Laptop Computers require the Parity setting to
be Odd.
When selections are completed, Press <ENTER> or click on OK. The screen will
return to the Model 235 Software's main screen and the reading in the digital
readout box should match the Model 235's LCD reading. Additionally, the
Bargraph under the digit readout should be changing with any shift in the
readings. If the reading in the LCD and screen's digital readout do NOT match,
stop here and correct the problem by reviewing steps 1-7. A momentary
mismatch (less than one second) is acceptable, but any other mismatch or no
reading indicates the serial communications path is not operating properly.
If the readings in the PC monitor screen's digital readout box match the Model
235's LCD correctly the serial communications is established and you are ready to
use any of the features and options.
