MAX197 Evaluation Kit
The MAX197 EV kit provides a proven PC board layout
to facilitate evaluation of the MAX197. It must be inter-
faced to appropriate timing signals for proper opera-
tion. Refer to the MAX197 data sheet for timing require-
ments.

straight-through, 9-pin female-to-male cable. If the
only available serial port uses a 25-pin connector, a
standard 25-pin to 9-pin adapter will be required.
The EV kit software checks the modem status lines
