The LK202-25-USB offers a single USB protocol for an easy connection to a host computer. This simple

and widely available protocol can be accessed using the on board mini B style USB connector as outlined

in the USB Connections section.

Recommended Parts

The External Mini USB cable is recommended for the LK202-25-USB display.

It will connect to the miniB style header on the unit and provide a

connection to a regular A style USB connector, commonly found on a PC.

USB Connections

The USB connection is the quickest, easiest solution for PC development. After driver installation, the

LK202-25-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 LK202-25-USB please follow the steps below.

1. Set the Protocol Select jumpers.

 USB: The LK202-25-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 USB.

Protocol Select jumpers on the USB model cannot be moved.

2. Make the connections.

 Plug the mini-B header of your External Mini USB cable into your LK202-25-USB and the regular

USB header into your computer USB jack.

3. Install the drivers.

a. Download the latest drivers at www.matrixorbital.ca/drivers, and save them to a known

location.

b. When prompted, install the USB bus controller driver automatically

c. If asked, continue anyway, even though the driver is not signed

d. When the driver install is complete, your display will turn on, but communication will not yet be

possible.

e. At the second driver prompt, install the serial port driver automatically

f. Again, if asked, continue anyway

4. Create.

 Use uProject or a terminal program to get started, and then move on with your own

development. A number of application notes are available at www.matrixorbital.ca/appnotes.
