Cable (EXTMUSB3FT)
The External Mini USB cable is recommended for the LK204-7T-1U-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
LK204-7T-1U-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 LK204-7T-1U-USB please follow the steps below.
1. Set the Protocol Select jumpers.

USB: The LK204-7T-1U-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 LK204-7T-1U-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.

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. Instructions for the former can be found below and a number of application
notes are available for the latter at
