[net.micro.hp] Line Drivers vs. Short Haul Modems ?

mark@cogent.UUCP (Mark Steven Jeghers) (10/16/86)

We are planning to install some HP equipment which will require peripherals
at distances longer than what RS-232 is comfortable with.  We are, however,
undecided whether Line Drivers or Short Haul Modems are more appropriate.
The equipment will be in an industrial manufacturing environment.  If any
net-people have any advice regarding the pros and cons of the two options,
we would love to hear from you by e-mail, after which we would post both
summary and credits.  Among the things we'd like to get input on is the
types of cables that are used with the two options (Line Driv./S.H.Modem),
e.g. twisted pair, coax, or whatever.

Thanks much

Did you look at the 8-channel fiber optic multiplexer.  It has high noise
immunity, longer distance and comes with 8 standerd DB-25 connectors on both
ends.

It could be usefull depending on your distance.
