You are unable to
establish a connection
between your computer
and the Serial
Converter. • If the status indicators are off, connect the
cables and apply power to the product.
• Configure your software and Serial Converter
to use the same COMM port and serial port
rate (baud rate).
After changing the serial
port rate, you are no
longer able to
communicate with the
Serial Converter and
connected product.
For example, in
HyperTerminal,
meaningless text
appears on the screen
when you press Enter.
In VS Utilities,
parameter values are
not updated.
Reset the serial port rate in the software.
Instructions are included here for resetting the
serial port rate in HyperTerminal and VS Utilities.
If you are using a different configuration tool,
refer to its user manual.
HyperTerminal
1. Select File > Properties, and then click
Configure.
2. Select the new baud rate, and then click OK.
3. Save and close HyperTerminal.
4. Double-click on your HyperTerminal file (*.ht)
to restart HyperTerminal.
5. Press Enter until the main menu appears.
VS Utilities
1. Select Explore > Configure
Communication.
2. Select the new baud rate. VS Utilities should
start updating values again. If it does not,
restart VS Utilities.
You set a new serial port
rate, but the Serial
Converter is still using
the old serial port rate. Reset the module. Refer to chapter 4.
No communications to
drive. • Verify cable connections.
