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.

Figure 35 shows the location of the digital board dip switches, and hardware reset switch. It also includes a detail view of the dip switch array, which indicates the arrangement of the switches from left to right and the “ON” and “OFF” directions.
