3.6. Current Settings 
 
The Current Settings section is broken down into two 
sections; Local Device Settings and Partner Device 
Settings.  Each field will be discussed further below. 
 
When the Current Settings has been selected, an 
additional section appears in the left-hand section 
called Default Settings.  Both sections can be 
expanded at the same time to enable the user to view 
the current settings and the default settings at the 
same time. 
 
As each section is opened, the previously opened 
section will close to prevent information moving off the 
bottom of the screen and thus requiring the user to 
scroll down. 
 
Whenever a setting is changed, the field changes 
colour to indicate that a change has been made but 
not applied.  
 
 
Baud Rate 
Click the drop down arrow at the far right of this field to display a list of popular baud rates. Due to some technical 
limitations, it is not possible for the product to achieve all of these baud rates exactly, although most of them are 
available to within 1%. Normal RS232 operation is not affected by such small differences in data rates unless very 
long streams of continuous data are being used. The Actual baud rate achieved is displayed next to your selection. 
 
This option is only applied when the “Apply” icon is clicked.  Along with updating the device, the application will 
immediately change its own communications parameters to match those new settings so it can continue to interact 
with the device. Multiple changes to communications settings are ALL applied when the “apply” icon is selected. 
 
NOTE: It is possible for the adapters to be configured to baud rates that are not supported by a PC’s COM port. If 
your application requires such a “non-standard” baud rate, you may no longer be able to communicate to the 
Adapter from your PC. If you “apply” the setting inadvertently, you can restore the default settings of the Adapter by 
performing a reset as documented below. 
 
The adapter’s normal factory set baud rate (and default baud rate) is 115200 baud. 
 
Parity 
Click the drop down arrow at the far right of this field to display the available options for Parity. 
This option is only applied when the “Apply” icon is clicked. Along with updating the device, the application will 
immediately change its own communications parameters to match those new settings so it can continue to interact 
with the device. Multiple changes to communications settings are ALL applied when the “apply” icon is selected. 
 
Stop Bits 
Click the drop down arrow at the far right of this field to display the available options for Stop Bits. 
This option is only applied when the “Apply” icon is clicked. Along with updating the device the application will 
immediately change its own communications parameters to match those new settings so it can continue to interact 
with the device. Multiple changes to communications settings are ALL applied when the “apply” icon is selected. 
 
Data bits 
Unfortunately this setting cannot be changed. Your RS-232 Adapter only supports the 8 data bit format. Thus there 
is not a configuration menu option for this setting.
