The baud rates listed in Table 3-3 as
requiring a jumper change can be made
available as described below. Please Note:
Such a jumper change will affect all four
ports.
1.
Locate JP13, turn the board so that the
solder side faces up, and cut one of the
traces as directed below.
A.
To implement one of the baud rates for
Output Value 03H:
Cut the bottom trace, as shown in Figure 3-9.
Then turn the board so that the component side
faces up, and install a mini-jump between the
pin marked with the speed you wish to specify
and the nearest pin marked "03H." Figure 3-8,
for example, shows where to install the
mini-jump to specify 150 baud.

B.
To implement one of the baud rates for
Output 04H:
Cut the top trace, as shown in Figure 3-9.
Then, turn the board so that the component
side faces up and install a mini-jump between
the pin marked with the speed you wish to
specify and the nearest pin marked "04H."
Figure 3-10, for example, shows where to
install the mini-jump to specify 75 baud.
