The LK204-7T-1U-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 LK204-7T-1U-USB
for an added
charge as part of a custom order. Please use the Contact
section to request
more information

friendly Matrix Orbital sales team.

The Alternate Power Connector provides the ability to power the LK204-7T-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.
