USB Connections
The USB connection is the quickest, easiest solution for PC development. After driver installation, the
LVK204-25-USB will be accessible through a virtual serial port, providing the same result as a serial setup
without the cable hassle. To connect to your LVK204-25-USB, please follow the steps below.
1. Set the Protocol Select Jumpers.
2. Make the connections.
3. Install the drivers.

USB: The LVK204-25-USB offers USB protocol only. Model specific hardware prevents this unit
from operating in any other protocol, and does not allow other models to operate in the USB
protocol. Protocol Select Jumpers on the USB model cannot be moved.
Plug the mini-B header of your External Mini USB Cable into your LVK204-25-USB and the
regular USB header into your computer USB jack.
Download the latest drivers at www.matrixorbital.ca/drivers, and save them to a known
location.
When prompted, install the USB bus controller driver automatically.
If asked, continue anyway, even though the driver is not signed.
When the driver install is complete, your display will turn on, but communication will not yet be
possible.
At the second driver prompt, install the serial port driver automatically.
Again, if asked, continue anyway.
Use uProject or hyperterminal to get started, and then move on with your own development.
Instructions for the former can be found below and a number of application notes are available
for the latter at www.matrixorbital.ca/appnotes.
