Description This command sets the RS-232 port to the speci?e
d [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.

Parameters
Parameter Length Description
speed 2 Inputed LSB MSB from baud rate
formula (12-2047).
Description This command sets the RS-232 port to a non-standard baud rate. The
command accepts a two byte parameter that goes directly into
theCrystalSpeed
1 to
modules baud generator. Use the formula,
speed
=
8×DesiredBaud
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.
