Quick-start guide

Introduction

You can use the ICUSB23208FD to convert a single USB port into eight RS232 serial

ports, and connect multiple hubs together to create a scalable and economical

solution.

The ICUSB23208FD adds eight RS232 serial ports with data transfer rates up to 921.6

Kbps and can be controlled by a desktop or laptop computer system using a single

USB port. The durable metal chassis ts into standard 19-inch server storage racks and

supports an extended -40oC to 85oC (-40oF to 185oF) operating temperature range that

allows for reliable use even in harsh environments.

The ICUSB23208FD also features daisy chain capability, allowing you to connect

multiple hubs through a single USB port.

Quick-start guide

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.

Quick-start guide

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.

Conrm 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

1. On your computer, press and hold the Option key and click the Apple menu.

2. Click System Information or System Proler.

3. Under Hardware, click USB.

The USB device tree lists all of the devices connected to each port.

Use the daisy chain feature

You can daisy chain up to three devices and add up to 24 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.

Quick-start guide

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.
