About Changing the Baud Rate

The 68K Monitor has the ability to change the communication speed of the D25 and D20 ME WESMAINT ports. This is useful when downloading large files.

Example: A 1 M code file may take upwards of 40 minutes to download at 9600 bps (the default). At 38400 bps, only 10 – 15 minutes.

Note:

Most PCs cannot exceed 115,200 bps, and some terminal programs

 

(Windows Terminal for example) may have other restrictions. Check the

 

respective program's User's Guide for help.

!

WARNING 1

The system will not save speed changes made using this command in NVRAM. The monitor will return to 9600 bps after a restart.

If you execute this command in a D25 monitor, it will modify the data rate of both the WESMAINT and the D25MAINT ports, since they run off the same data rate generator.

GE Energy Services recommends that you use this command only to speed up a serial download, and not to redefine the operational state.

!

WARNING 2

Enter the baud rate correctly, as the function is capable of setting the data rate to any value.

Example:

Forgetting to enter the final zero when trying to change the data rate to 19200 bps would result in a rate of 1920 bps, preventing any further communication. A reboot will return the speed to the 9600 bps default.
