5.3 Connecting to a Computer
Connect to the computer with a standard (straight-through) serial cable.
Use HyperTerminal or similar terminal software to test communication with the computer.
Set up HyperTerminal as follows:
Choose New Connection, “connect using” COM1 (or available COM port).
Select Baud=9600; Parity=8 None; Stop=1; Handshaking=None. Click OK.
Choose Properties/Settings, then ASCII Setup. Check boxes as illustrated:
(Send line ends…; Echo typed characters…; Wrap lines…)
Verify communication by pressing the Print button. If HyperTerminal is set up properly, the value on
the display will be displayed in the window.
5.4 Connecting to a Serial Printer
Connect the cable supplied with the printer to the scale’s RS-232 port.
Make sure that the indicator and printer communication settings match.
Test communication with the printer by pressing the Print button. If the indicator and printer are set
