BX-35 circuit diagram - Andy Lomas - Sep 21 23:35:00 2002

I'm using a BX-35 that I want to migrate from the development board
to a dedicated circuit board.

The only circuit diagram I can find in the docs for how to connect up
the BX-35 with a serial connection for COM1 is the circuit diagram
for the development board. (I might be blind... but I can't find
anything else...)

Am I right in assuming that I need to connect up serial port lines
via various inverters through a 74HC04 chip? Has anyone a simpler
circuit diagram?

tx (in advance!)

Andy

This weekend I decided to tackle the BX35 and the only schematic I
found was the one you mention. I built up a number of proto systems
which appears at http://www.phanderson.com/basicx/BX35.html

Inverters are required on the Tx and Rx leads. On the PC Tx there is
a series 100K to protect the inverter from the negative voltage
normally present on the PC Tx lead.

There was an error on this schematic which showed the ATN lead as
being term 16. It should be terminal 2.

Send me e-mail at e-mail pha(at)phanderson.com and I will e-mail you
a scan of my schematic in .pcx format.

No, you're not blind, we've just been a bit tardy in posting BX-35
information. Just to add to Peter Anderson's response, also check
out:

Also, I'm happy to say the broken links have been fixed on the
BX-35 page:
