Problem Corrective Action
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 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 adapter. Refer to Chapter 4.
You are using VS Utilities
and you cannot perform
any of the following:
• Route out over a
network, such as
DeviceNet to another
drive.
• Access DPI
peripherals such as
the RECOMM-DNET
DeviceNet adapter.
• Access 32-bit data.
• Reserved (16) must be set to “Auto.”
• Reset the converter. See section 4.4.3.
