Can I safely put the daughtercard into a stock Wyse 60 and get the same
functionality? What is the max distance for RS232? Are there any other
real differences? The Wyse was stationed only about 50 feet (cable wise,
crow flies about 8 feet thru a wall) from the KSU. Is that close enough
that a stock RS232 based Wyse can reach?
My Qume system is a different story, that is about 300 feet cable wise
from the KSU.
(Although, it might be possible that the one in the Qume is fried, that
terminal "works" it just doesn't pick up anything over the serial port...
it stopped working when the phone pole in front of my building was struck
by lighting, and due to poor grounding on the part of the phone company,
half my phone system was fried, including the terminal... BUT... that
gives me the idea of pulling the daughtercard from a 2nd one of the
Qume's I have that has a bad powersupply... or was that a screen... humm,
if it is a screen, maybe I can just mix and match and get one working)
I would think the Executone terminal you have is fairly similar to the
Isoetec I have. Executone bought Isoetec many moons ago, because Isoetec
had better designs and systems. Most of the executone systems released
after the buyout have been based off Isoetec designs/ideas.
