North Star HSIO-4
The baud rates listed in Table 3-6 as
"Alternatives (With Jumper Change)" can be made
available as described below.
a jumper change effects all four HSIO-4 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 3-22.
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 3-21, for example, shows where to
install the mini-jump to specify 55.8KHZ.

B.
To implement one of the baud rates for Output
Value 04H:
Cut the top trace, as shown in Figure 3-22.
Then turn the board so that the component
