Cable (EXTMUSB3FT)

The External Mini USB cable is recommended for the LK162B-7T-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
LK162B-7T-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 LK162B-7T-USB please follow the steps below.

1. Set the Protocol Select jumpers.

USB: The LK162B-7T-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 LK162B-7T-USB and the
regular USB header into your computer USB jack.
