The six pin RS422 interface header of the LVK204-25-422 offers power and ground connections as well
as two differential pair communication lines. Regular and
inverted lines
are provided for both receive
and transmit signals. Power is supplied locally to the regular or –V variants while the –VPT can receive
power over a distance. The Tyco 282834-6
style header
is most suited to a simple wire connection.

The Alternate Power Connector provides the ability to power the LVK204-25-422
using a second cable.
This is particularly useful for the regular or -V modules that are to
be powered locally. The Tyco 171825-
4 style header will fit a floppy power cable from a PC power supply for a simple bench power solution.
