Troubleshooting the WindowsDirect Communication Function
If the WindowsDirect communication function doesn't run properly, check the following points.
If this doesn't resolve the problem, contact your Shimadzu representative.
Q1 WindowsDirect communication has been set but it is not operating at all.
A1
Check the type of communications cable used for the connection (Shimadzu authorized part
or another part available on the general market) and the soundness of the connection.
If a USB serial converter is used, depending on the circumstances at the setup there is a
possibility that it has been automatically set to a COM port number higher than 4, and in
this case you should reassign it to a COM port number that can be used by serial key devices
(COM1 to COM4).
It is possible that the driver used as an accessory with the USB serial converter has not been
set up properly. Try uninstalling the driver and installing it again.
Some notebook PCs feature a setting for disabling RS-232C ports as a power-saving measure.
Before trying to use the WindowsDirect communication function, make the setting that
enables the use of RS-232C ports.
Communications with other applications and PCs via a LAN may interfere with the serial key
device settings. Try using WindowsDirect communication without using the LAN.

Q2 The WindowsDirect communication function won't work after I restart the PC.
A2
Some PCs don't recognize that a serial key device has been set when they start up. For details
on how to deal with this, contact your Shimadzu representative.

Q3 I want to use the WindowsDirect communication function with Windows Vista.
A3
Windows Vista doesn't have the serial device setting screen that is required to set the
WindowsDirect communication function. For details on the setting, contact your Shimadzu
representative.

Q4 Data is input to the PC as garbled characters.
A4
Either the balance or the PC is not set for the WindowsDirect connection function. Make the
settings again by referring to "Setting the Function" (^ page 111).

Q5 When data is input into Excel, the cursor doesn't move to another cell.
A5
If a function for conversion to 2-byte characters is available in Windows, turn the setting for
this function off.
Click the [Edit] tab under [Options] in Excel and check [Move selection after Enter] (if cells
move in response to keyboard input there is no problem).
Check the input data in another application (e.g. Notepad).

Q6 The operation is sometimes abnormal.
A6
Depending on the processing capability of the PC, malfunctions may occur if the
communications speed is high. Set 300 bps for the communication speed. Malfunctions may
also occur if the interval for data transmission from the balance is too short. Ensure that one
batch of data is displayed on the screen before the next batch of data is sent. And if there is
limited processing capability, don't use the continuous output function.
When data is sent from the balance, don't touch the PC's keyboard or mouse.
