2 Basic Stamp 2sx

Hello Group:
Maybe you didn't understand my last message I hope
that you understand it.
Can I connect the SOUT pin of one basic 2sx to Pin 14
as input of other basic 2sx and the SIN of the first
basic 2sx to the pin 15 as output of the second one
basic 2sx directly and talked RS232?
Thanks.

Hi Alberto,
Yes. The i/o addressed to p16, SOUT and SIN, will always be
"inverted". Match that on the other stamp. It may improve the
signal speed if you install a 2k ohm resistor from SOUT to Vss.
I am not sure if you are referring to the physical pins 14 and 15 on
the chip, which are logical pins P9 and P10, or logical P14 and P15,
which are on physical pins 19 and 20. The idea is the same either
way.
