The six pin RS422 interface header of the GLK19264A-7T-1U-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 –LV 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 GLK19264A-7T-1U-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.
