Hello,

Is it possible to increase the baud rate of the RS232 E-block above 38k? I am using the PIC16F877A. If not, is this a hardware issue... i.e. would I be able to do so if I had different hardware?

Thanks,
Phil

Hello,

Higher Baud rates can be specified using the custom option in the Baud rate drop-down box. The required Baud rate can then be entered into the Custom Setting text box. A % timing error value is calculated, based on the best register settings for the crystal frequency being used.

The PIC data sheets indicate that Baud rates upto Fosc/16 can be generated.

The data sheet for the MAX232 chip, used on the RS232 E-Block, specifies a maximum data rate of 120K bits/sec.

Thanks Sean!
