The LK202-25/VK202-25-USB comes with a familiar Mini USB Connector to fulfill both communication
and power needs. The standard MiniB style header can be connected to any other USB style using the
appropriate cable. Most commonly used with a PC, this connection creates a virtual com port that
offers a simple power solution with a familiar communication scheme.
Alternate USB Header
Some advanced applications may prefer the straight four pin connection offered through the Optional
Alternate USB Header. This header offers power and communication access in a simple interface
package. The Optional Alternate USB Header may be added to the LK202-25/VK202-25-USB for an
added charge as part of a custom order. Please use the Contact section to request more information
from the friendly Matrix Orbital sales team.

The Alternate Power Connector provides the ability to power the LK202-25/VK202-25-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.
