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.
