Black Box IC476A-F-R2 Manual De Usuario

Once you have properly configured the Converter and connected the

twisted-pair wires correctly, simply plug the Converter directly into the

DB25 port of the RS-232 device. After doing so, remember to insert and

tighten the two captive connector screws.

If you must use a cable to connect the Converter to the RS-232 device,
make sure it is a straight-through cable of the shortest possible length.
We recommend no more than 6 ft. (1.8 m).

The Converter supports multipoint applications using daisychain topology.
Using a daisychain topology, you may connect several Converters together

in a master/slave arrangement. Maximum distance between the units will

vary based upon the number of drops, data rate, wire gauge, etc.
The illustration below shows how to wire the two-pair (4-wire) cables

properly for a daisychain topology. Note that the ground connection is not

needed.

Connections are to screw terminals directly on the Converter.
