The six pin RS422 interface header of the GLK24064-25-422/GLT24064-422 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 GLK24064-25-422/GLT24064-422 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.
