4.1.3 Digital Board DIP Switch
The digital board is mounted inside the LRP2000 enclosure closest to the wall with the cable entries. The
first five switches of the main board set the COM1 baud rate, electrical interface, and the download options
for COM2. SW6, SW7 and SW8 are not used and should remain OFF. When SW1 and SW2 are both set
ON, the baud rate is set via the Configuration Menu. Table 12 lists the possible switch settings for typical
applications.
