Properties to ‘19200 8-N-1’ and use ‘Direct Connection’ to the chosen Com port. Use a 1:1 cable
(not ‘crossover’) to connect to the PC Com port.
6. The addition of LEDs to the handshake lines provides a useful diagnostic tool.

Notes
1. Processor running at full speed. Contact the Sales Office for details of special low power variants.
2. The ‘Host Ready Input’ and the ‘Serial Data Input’ have ‘weak’ internal pull-ups enabled. These
inputs should not however be left ‘floating’ but should be tied to either Vcc or Ground 0 Volts.
3. When power is first applied to the module the processor retrieves ‘calibration’ data for the RF section
that compensates for temperature and power supply voltage variations. The transceiver will then be
