Table 2(a): SW2 (Baud Rate)


SW2 has a row of 4 DIP switches. Two is used to determine the baud rate while another two is used to
indicate the communication type.

Table 2(b): SW2 (Communication Type)


The communication type is a setting that lets the BioPointe know how to respond to incoming data from the
host. For example, if the Modem type is chosen, the BioPointe has to be able to respond to 'AT' commands
coming from the modem.

Table 3: SW3 (Serial Communication Type)


In Table 3, you will see the serial communication type. This is different from the communication type. The
serial communication type lets the BioPointe know what type of signals is to be expected. For example,
RS232 is single-ended, while both RS422 and RS485 are differential.
