3.2.4.4 Troubleshooting
When the Function Does Not Operate At All:
• For some notebook PCs, it is possible to exclude the RS-232C port for energy saving purposes. Set
the PC so that the RS-232C port can be used.
• Change the settings of COM 1 to 4. Re-start Windows®* after the changes are complete.
• Verify that the correct RS-232C cable is being used.
Windows®* = Windows 95, Windows 98, Windows Me, Windows 2000
When the Function Intermittently Malfunctions:
• Use a communication speed of 300bps. Depending on the processing ability of the PC, this function
may operate incorrectly if communication speed is too high.
• Send the next data only after the current one is displayed on the screen. Depending on the processing
ability of the PC, this function may operate incorrectly if interval of data transmission is too short.
• Do not touch the keyboard or the mouse while the balance is transmitting data.
Stop the data transmission and confirm that no data is entering the PC before touching the keyboard
or the mouse.
• This operation may be incorrect when the displayed value is not a weight value (i.e. error code or
time).
• The unit designation is not transmitted.
• This function may operate incorrectly depending on the settings of various lock keys of the keyboard
such as the NUMLOCK or cursor key lock. Change the state of the lock and function keys on the PC
keyboard.
• The peripheral devices connected to the DATA I/O such as Electric Printer EP-50 cannot be used
with this function.
• When this function is used, a command cannot be sent from the peripheral device to the balance.
• Set the data formats, such as decimal places and units, in each application.
