Selecting 0 immediately returns you to the previous menu. Any changes made in this menu will be remembered
when leaving, and will be applied by selecting option 4 “Apply COMM Settings” from the previous “Modify COMM
Settings” menu. Selecting any other option will store the appropriate configuration selection.
A range of popular pre-set baud rates is offered in this menu along with an option for you to set your own. Due to
some technical limitations, it is not possible for us 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 long streams of continuous data are being used. The Actual baud rate achieved will be displayed next to
your selection.
4.2.1.1. Entering your own baud rate
Selecting option (d) from the “Set Baud Menu” allows the user to configure BL-521 to operate at any baud rate
the user desires between 244 baud and 1.3M baud. BL-521 will calculate the nearest actual baud rate it is able to
achieve and display it next to your selection, as shown in the configuration menu’s below.
