1.7.4 SERIAL CONNECTION SETUP
After connecting the DB9 serial port to a PC, start the HyperTerminal application and create a session using the
following parameters:
Port Speed: 9600 bd or 300bd (see below)
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: XON/XOFF
See section 3.1 for proper selection of the operation mode when main power is removed:
A jumper across pins 2-3 (VBAT-GND) of JP16 indicates that no external battery is available. The IC
will stay in brownout mode when the system power is down and it will communicate at 9600bd.
A jumper across pins 1-2 (BATMODE-VBAT) indicates that an external battery is available. The IC will
be able to transition from brownout mode to sleep and LCD modes when the system power is down
and it will communicate at 300bd.
HyperTerminal can be found by selecting Programs Accessories Communications from the Windows
start
menu. The connection parameters are configured by selecting File Properties and then by pressing the
