Installation
You can use the power adapter or the two-wire terminal block power input (9-36V DC)
to power the USB serial hub. You can also use redundant power input by connecting
both the power adapter and the terminal block power, and in the event that your
power source fails, the USB serial hub will switch to use the secondary power source.
Install the USB serial hub using the power adapter
Warning! Make sure that the driver installation is complete before you plug in and
connect the USB serial hub.
1. Insert the provided driver CD into your host computer.
Note: The CD should automatically open and display all of the folders contained on the
CD. If that doesn’t happen, navigate to the CD/DVD drive on your computer.
2. In the driver folder, double-click the appropriate setup le for the OS that you’re
currently running. The driver installation wizard will begin installing the driver and
automatically close when the installation is complete.
3. Connect the provided USB cable to the USB Type-B connector (host) port on the
USB serial hub and the USB port on your computer.
4. Connect the universal power adapter to the DC power connector on the USB serial
hub and a wall outlet.
Install the hub using the terminal block power input
Warning! Make sure that the driver installation is complete before you plug in and
connect the devices to the USB serial hub.
1. Insert the provided driver CD into your host computer.
Note: The CD should automatically open and display all of the folders contained on the
CD. If that doesn’t happen, navigate to the CD/DVD drive on your computer.
2. In the driver folder, double-click the appropriate setup le for the OS that you’re
currently running. The driver installation wizard will begin installing the driver and
automatically close when the installation is complete.
3. Connect the provided USB cable to the USB Type-B connector (host) port on the
USB serial hub and the USB port on your computer.
4. If the terminal block connector is already inserted in the USB serial hub, use a small
at-head screwdriver to loosen the screws to the left and right of the terminal block
connector until you can remove it from the USB serial hub.
5. Use a small at-head screwdriver to loosen the two screws located on the top of the
terminal block connector.

6. Connect the positive and negative wires from your DC power source to the
corresponding terminal block connectors.
Note: Make sure that the polarity of the input power, positive (+) and negative (-), is
matched correctly with the terminal block pins.
7. Tighten the two screws located on the top of the terminal block connector.
8. Reinsert the terminal block connector into the USB serial hub and tighten the
screws to the left and right of the terminal block connector.
Conrm installation
Windows OS
1. On your computer, navigate to Device Manager.
2. Expand the Ports (COM & LPT) option.
3. Verify that the additional COM ports are listed.
4. Double-click a port and review the device properties.
Mac OS

You can daisy chain up to three devices and add up to 48 ports in total.
1. Connect the ICUSB23208FD to your host computer. For more information about
how to do this, see “Installation.”
2. Connect a USB cable to the USB Type-A connector (daisy chain) on the
ICUSB23208FD connected to your host computer and to the USB Type-B connector
on the serial hub that you want to daisy chain.
3. If you’re connecting a third serial hub, connect a USB cable to the USB Type-A
connector (daisy chain) on the second serial hub and to the USB Type-B connector
on the third serial hub that you want to daisy chain.
4. On each of the USB serial hubs, connect the universal power adapter to the DC
power connector or the Two-wire terminal block input and a wall outlet.

Perform a serial loopback test
To verify that a port is operational and to map the ports, you should perform a serial
loopback test. A loopback test sends and receives data to and from the same serial
port. To complete the loopback test, you need to temporarily connect pin two and pin
three to allow the signals to be sent and received on the same port.
To perform a serial loopback test, you need a loopback adapter and a third-party
software program (for example, PuTTY or HyperTerminal®).
1. Download a third-party software program.
2. Open a connection on the COM port that you want to test.
3. Insert the loopback adapter into a serial port.
4. Type something in the third-party software.
If what you typed is displayed in the window, you have located the correct port. If the
text isn’t displayed in the window, move the adapter to another port and try again until
you nd the correct port.
Mount the serial hub in a server rack
The ICUSB23208FD comes with the necessary hardware to install the serial hub in a
regular server rack or on DIN rails.
1. Do one of the following:
• Use the rack-mounting screws to attach the two rack-mounting brackets to
both sides of the serial hub.
• Use the DIN-rail mounting screws to attach the two DIN-rail mounting brackets
to both sides of the serial hub.
2. To mount the serial hub in your server rack or on DIN rails, follow the instructions
that came with your server rack or DIN rails.
