Getting Started
To ensure safe operation the supplied plug must be inserted only into a standard power outlet that is properly
grounded through the standard electrical wiring. Non grounded equipment may cause an electrical shock
hazard, and may cause excessive electrical noise radiation.
The interface cable is not a standard accessory. Please purchase the appropriate interface cable for the
interface you intend to use (USB or Network).
DO NOT connect the interface cable at this time. Connecting the interface cable is done during the software
installation process.
USB interface cable
Please make sure you use a USB 2.0 interface cable that is no longer than 2 metres. When you use a USB
cable, make sure you connect it to the USB port of your computer and not to a USB port on a keyboard or non-
powered USB hub.
Network cable
Use a straight-through Category5 (or greater) twisted-pair cable for 10BASE-T or 100BASE-TX Fast Ethernet
Network.
