Communicating with the BioPointe

Step 1: Power off device
Connect the pair of power supply wires as shown in the figure below. Ensure that the location of each wire is
correct. Keep the device powered off so that any wrong connection later will not damage the device.
Step 2: Connect Cables
Pins 3 to Pin 7 are designated for different signal depending on the type of serial communication selected.
(Pin 8 is currently not used for serial communication.) If you are communicating via a modem, you can
connect using RS232, RS422 or RS485 mode, depending on the number of BioPointe devices you need to
communicate with. Please refer to the appendix for a description of the modem connection setup.
