Troubleshooting
Fast, Easy Answers...
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 flyout window. You should see the
new ports. If there are no exclamation points or
other trouble indicators ports are installed
correctly and ready for use.
Are My Devices Wired As DTE or DCE?
(How to Check)
1. Use Rule of Thumb
If the device plugs into the computer serial
port and works normally, the device is wired
as DCE (or the connection cable is a crossover
type that makes it work as a DCE). If the device
connects to the computer port using a “null
modem” crossover cable, it is wired as DTE.
2. Use RS-232 Line Tester
A quick and easy way to determine the DTE/
DCE port type is to use a RS-232 line tester
such as the 9PMTT. The tester can show the
signal state of any active RS-232 data lines using
LEDs lighting Red or Green. Active data lines are
output from a device. They may be either
High or Low.
