Perfect.
It is a point-to-point RS-485 link, in this particular installation, not
multi-drop, fortunately.
I presume I would just tie the enable pins to "true"
The RS-485 device in question is a simple 4-wire transmit/receive pair.
Thanks for the pointers,

I have a need
to build a serial converter down here. ISTR RS-422 drivers
are something like 26L32s, which we have. What I'm not sure of is what
26LS31 drivers, 26LS32 receivers IIRC. to use for the
RS485 end. Any suggestions? Obviously, I'll have to use
I seem, to rememebr using the TI SN75176 chip for this. I assume you're
using multiple drivers on the RS485 bus, so you'll need to find some way
of controlling the enable pins of the 75176.
