QUICK START
GUIDE
The 485USBTB-2W cannot be used as an RS-
422 device or as 4-Wire RS-485.
One USB port is required for each installed
device. The USB port can be native to the PC or
it can be a USB port on a USB hub that is
connected to a PC.
The device works with USB 1.1 or 2.0 ports. But,
it has a maximum USB data rate of 12 Mbps.
To verify the installation, you may open the
Windows Device Manager.
Scroll down to Ports.
Expand the yout window.
You should see the new ports. If there are no
exclamation points or other trouble indicators,
the ports are installed correctly and ready for
use.
Serialized - Every unit is assigned a unique
COM port and the install process is required for
every unit. Ideal application: xed locations.
-LS (Locked Serial Number) - Same type
model numbers share the same COM port and
require only one install process for each model
type. Ideal application: eld service.
When ordering Locked Serial Number versions,
add an -LS to those models.
