Setting the DIP Switches (SW1, SW2, and SW3)
Note: Cycle BioPointe reader power after changing any DIP switch settings so
the reader will recognize the DIP switch change.

The BioPointe reader has three DIP switches:

SW1 – Sets the Device ID
SW2 – Sets the baud rate and communications type
SW3 – Sets the serial interface type (RS232, RS422, or RS485)

SW1: 8 mini-switches to set Device ID from 1 to 254 – refer to the BioPointe
Device ID Addressing Table. Device ID 0 is reserved for TCP/IP – LAN-50
devices. Device ID 255 is invalid.
