The six pin RS422 interface header of the GLK240128-25-422/GLT240128-422 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 GLK240128-25-USB/GLT240128-USB

using a second cable. The Tyco 171825-4 style header is particularly useful for connecting to an

unmodified floppy power cable, a 171822-4 for example, from a PC power supply for a simple bench

power solution.
