SERIAL INTERFACE

A RS-232 interface is used as a hardware link between the TPS1100 and an
external computer.
Signal paths
Voltage levels
Baud rate
Parity
Data bits
Stop bits
Terminator
The default settings for the interface are 19200 Baud, 8 data bits, 1 stop bit, no
parity. The communication terminator is set to CR/LF. The parameters marked as
'Fixed' may not be changed. The other parameters are variable may be changed by
the user.

DEBUGGING UTILITY

When debugging communicating systems it may be hard to locate the source of an
error. Especially in combination with radios to communicate wireless, the number
of error sources increases. The following should be checked carefully therefore:
