Description This command sets the RS-232 port to the speciﬁed [speed]. The change

takes place immediately. [speed] is a single byte specifying the desired

port speed. Valid speeds are shown in the table below. The display

module can be manually reset to 19,200 baud in the event of an error

during transmission, including transmitting a value not listed below, by

setting the manual override jumper during power up. However, it should

be noted that this command will be ignored until the manual override

jumper is removed again.

command accepts a two byte parameter that goes directly into the

modules baud generator. Use the formula, speed =

− 1 to

calculate the [speed] for any baud rate setting. The speed can be

anywhere from 12 to 2047 which corresponds to a baud range of 977 to

153,800 baud. Setting the baud rate out of this range could cause the

display to stop working properly and require the Manual Override

jumper to be set.
