Installation

1. Connect the USB adapter into an available USB port on the computer. If the USB

adapter is unable to draw enough power from the USB port, connecting an external

power adapter (not included) may be required.

2. Insert the Driver Installation CD into the computer’s CD/DVD drive.

3. Access the CD and go into the “USB_to_IO \ FDTI” folder. Enter the folder for the

operating system of the computer system.

4. Run the driver installation program (e.g. CDM20600.exe) and follow the prompts.

Once the installation program nishes, the drivers for the adapter should be

installed. Unplug and reconnect the adapter if not.

5. Set the DIP switches on the bottom of the unit to the appropriate serial mode (see

“How to Use”).

6. Connect the serial devices to the DB9 serial connector (S1) and/or the 5-wire

Terminal Block serial connector (S2).

7. If mounting the USB adapter to a wall or surface, rst mount the included wall

mount bracket to the surface with four mounting screws (not provided). Make sure

to use the appropriate type of mounting hardware for the intended wall/surface.

8. Once the bracket is mounted, the USB adapter can be placed into the bracket and

it will simply snap into place. The USB adapter can be removed from the bracket by

simply pulling it free.
