Once you have removed the top cover, set switch position 1 ON to enable
communication mode. In this mode, the ON switch positions for switches 2-8
are defined in
Table 3 .
An example jumper setting for this switch is shown in Figure 5 .
When switch 1 is set to the ON position, RS-232 port is activated. Switch 2 set
to ON indicates that handshaking is enabled. With handshake enabled, switch
3 set to OFF indicates software handshaking. Switch 4 set to ON enables parity
checking. Switch 5 set to OFF indicates odd parity.
Switches 6 through 8 combine to indicate baud rate. See Table 4 for switch
settings and their corresponding baud rates. Switches 6 and 8 set to ON and 7
set to OFF combine to form a RS-232 baud rate of 9600 as shown in
Table 4 .
