APPENDIX A - NULL MODEM & FLOW CONTROL JUMPERS

You can configure the adapter’s serial interface to enable flow control and null modem signaling. You access the jumper

block by removing the cover from the Bluetooth serial adapter. Figures 10 and 11 show the jumper settings.

WARNING: Flow control signals are NOT RS-232 signaling tolerant. If you enable these signals with the jumpers, do not

exceed 3.3-V DC or permanent damage can occur.
