The USR602 can run on 5 V USB power if the host
port is providing 500 mA. It can also be powered
via the terminal block or barrel jack port.

Set the converter to RS-232 mode using the DIP
switches. Loopback pins 2 and 3. Using Hyper Termi-
nal or similar program, connect to the COM port. Set
the desired baud rate. Ensure that Hyper Terminal
local echo is OFF. Transmit data. If the same character
string is returned, the test is good.

To prevent installation errors, do not plug in the hard-
ware until you have already installed the drivers.

Use the included CD to install the converter’s drivers in
the attached PC.

When you connect the converter to the host
computer’s USB port the Found New Hardware
wizard will open. It will discover and install the
USB device. Then it will discover and install each
serial port. Allow Windows to install the converter
“Automatically.” There is no need to connect to the
Internet or Windows Update.

If a popup window says the software has not passed
Windows logo testing, that’s OK. Just click on
“Continue Anyway.”

When the wizard is complete the serial ports on the
converter will appear in Windows Device Manager
as new COM ports.
