CHAPTER 2: Introduction  
2. Introduction  
2.1 Overview  
The USB Directors RS-232 are intelligent expansion  
modules that connect to a PC or server running  
®
®
Microsoft Windows 95, 98, 98 SE, or 2000, Windows  
®
®
®
CE , Windows Me , or Windows NT 4.0 through the  
Universal Serial Bus (USB), providing easy, high-speed  
serial connectivity to equipment that uses the standard  
RS-232 serial interface, including modems, printers,  
point-of-sale (POS) terminals, and industrial-control  
devices.  
The USB Directors RS-232 have a Type B USB  
connector for a cable running from the USB port of a  
computer, USB hub, or USB switch. They’ll also have  
one (product code IC1000A), two (IC1001A), four  
(IC135A), or eight (IC1002A) DB9 male RS-232 ports,  
pinned like the serial ports on a PC, to which you can  
connect your RS-232 devices. The USB Directors allow  
you to control one or more RS-232 devices without using  
the RS-232 ports on your computer. All models except  
the IC1000A are stackable.

3.2.3 WINDOWS NT  
Because Microsoft does not support USB in NT4.0, we  
supply a USB stack that will be installed along with the  
necessary drivers.  
NOTE  
You must install the drivers using an account that has  
administrative privileges!  
To install the USB stack and USB Director RS-232  
drivers, either:

21  
USB DIRECTORS RS-232  
4. Operation  
Once you finish installing the hardware and software of  
the USB Director RS-232, it will operate continuously  
without requiring further intervention on your part.  
4.1 Interpreting the LED (IC135A, IC1001A, and IC1002A Only)  
The IC135A, IC1001A, and IC1002A models have a  
tricolor STATUS LED that tells you various things about  
how the unit is operating:  
• It lights red to indicate a loss of USB  
communication with the host. If the loss is due to  
unplugging the USB Director RS-232, the LED will  
blink red for a few moments before turning green  
when you reconnect the unit. If the loss wasn’t  
caused by unplugging the unit, the LED indicates  
a problem with the drivers, which may need to be  
reinstalled. The LED will also blink red during  
installation until the installation is complete.  
• It lights amber to indicate serial-port activity on the  
USB Director RS-232. The LED might also flash  
amber briefly during installation.  
22  
CHAPTER 4: Operation  
• It lights green to indicate that the USB Director  
RS-232’s serial ports are successfully set up and the  
unit is operating normally, but there’s not  
currently any data activity.  
4.2 Using the Edgeport Utility Program  
4.2.1 FOR ALL WINDOWS VERSIONS EXCEPT WINDOWS NT  
The CD also contains a USB Director RS-232  
configuration utility program called “Edgeport” that  
allows you to manage various resources of your USB  
Director RS-232. You can check the mapping of each  
physical communications port to your Windows COM  
port numbers. You can reassign the physical ports on  
your USB Director RS-232 to any available Windows  
COM port number from 1 to 255, or give your USB  
Director RS-232 a user-friendly Device Name. This  
capability is particularly helpful if you have more than  
one USB Director RS-232. You can also check the  
version numbers and get other information about the  
USB Director RS-232 drivers.  
Advanced USB Director RS-232 options are:  
1. Clicking the Uninstall button will remove the USB  
Director RS-232 device drivers and utilities.  
23  
USB DIRECTORS RS-232  
2. Allows you to configure how COM ports will be  
assigned.  
The driver supports COM-port number assignment in  
two ways:  
1. Assigning COM ports based on units’ serial  
numbers. This is the default setting. In this mode,  
the driver uses the serial number of each unit to  
uniquely identify it, and the COM-port  
assignments for a given unit are based on its serial  
number. No matter which physical USB port a unit  
is plugged into, it will maintain its assigned COM-  
port numbers.  
2. Assigning COM ports based on physical USB port.  
In this mode, the driver identifies a unit based on  
the physical USB port it is plugged into. This  
effectively assigns COM-port numbers to physical  
USB ports. No matter which unit is plugged into a  
given USB port, it will use the COM-port numbers  
assigned to that USB port. This permits one unit  
to be replaced with another, and, although the new  
unit has a different serial number, it will receive the  
same COM port assignments as the old unit because  
they were both plugged into the same USB port.  
24  
CHAPTER 4: Operation  
When using this mode, units are identified not  
by their serial number, but by a 2- to 7- digit  
number that identifies which USB port they are  
plugged into.  
After changing this setting, you will need to reboot  
before the change takes effect.  
4.2.2 FOR WINDOWS NT  
From the Start menu, select Programs, then Edgeport  
Utilities, then Edgeport Configuration Utility. The USB  
Director RS-232 Properties dialog box contains the same  
functions described in Section 4.2.1. Note, however, that  
you must have administrative privileges in order to  
change the COM-port settings.  
4.3 Using the USB Status Utility (Viewer) for Windows NT  
If you’re running Windows NT, the USB Status Utility  
can be accessed by clicking the USB icon in your system  
tray or by clicking on Start, then Programs, then Black  
Box Utilities, then USB Status Utility. This utility lists all  
the USB devices installed on your PC and provides other  
relevant information for each device. You may also use  
this utility to create a log file.  
25  
USB DIRECTORS RS-232  
5. Troubleshooting  
5.1 Using USB with Windows 95  
If you’re having difficulty installing or operating your  
USB Director RS-232 in a Windows 95 system, check the  
revision level of your copy of Windows 95. If you are  
using Windows 95 OSR2.1 or above, take the steps  
described in Sections 5.1.1 through 5.1.4. If not, you will  
need to upgrade to a more recent version of Windows.  
5.1.1 CHECKING FOR USB HARDWARE  
To verify that the necessary USB host controller is  
installed in your system, make sure that your PC has  
USB connectors. If it doesn’t, your PC will not support  
USB regardless of which Windows version it’s running.  
You will need to purchase a PCI USB controller card.  
If your PC has USB connectors, verify that the USB  
hardware is enabled in your system BIOS configuration.  
In some cases your manufacturer may have elected to  
ship your PC without the USB-support drivers installed.  
If the two USB-hardware listings that should be there  
(“root hub” and “host controller”—see Section 5.1.3)  
are absent in your Device Manager, you will need to  
upgrade to a more recent version of Windows.  
26  
CHAPTER 5: Troubleshooting  
After installing USB Support from your Microsoft  
Windows 95 OEM system disk, check your Device  
Manager again. If the two devices are not present or  
Windows Plug & Play does not autodetect the USB  
Director RS-232, try the following:  
1. If only the host controller is listed in the Device  
Manager, delete it from the Device Manager and  
reboot.  
2. If other USB devices are listed in the Device  
Manager, open the System Properties window  
from the Control Panel and select “Check for a  
device labeled ?UNKNOWN.” If the root hub and  
host controller are listed, then delete them from  
the Device Manager and reboot.  
If, after rebooting, the Add Hardware Wizard finds the  
USB devices and requires new drivers, such as  
UHCD.SYS, the drivers should be available in the  
C:\WINDOWS\SYSTEM directory. If, after following  
these procedures, you are still having installation  
problems, please call Black Box Technical Support as  
described in Section 5.2.  
27  
USB DIRECTORS RS-232  
5.1.2 DETERMINING THE LEVEL OF USB SUPPORT  
If you have an earlier version of Windows 95 than  
OSR2.1, you will need to upgrade to a more recent  
version of Windows. Otherwise, to determine if your  
system supports USB, take the following steps:  
1. Insert the Black Box driver CD into your CD-ROM  
drive.  
2. In the START menu, select RUN.  
3. Type “X:\Win95\usbready” (where “X” is the drive  
letter of your CD-ROM drive).  
One of two USB System Checker dialog boxes will  
appear. If your system does not support USB, the text in  
the dialog box will read, “This system DOES NOT  
currently support USB!” If you see this, take the steps  
described in Section 5.1.4. If your system does support  
USB, the text in the dialog box will read, “This system  
DOES have support for USB,” and you may continue  
with the Windows 95 installation instructions for your  
USB Director RS-232.

CHAPTER 5: Troubleshooting  
5.1.3 CHECKING FOR FULL USB SUPPORT IN THE DEVICE  
MANAGER  
To determine whether the Windows 95 Device Manager  
fully supports USB, take the following steps:  
1. From the main desktop area of Windows, right-  
click on the My Computer icon and choose  
Properties to open the System Properties window.  
2. Click once on the Device Manager tab to view a  
listing of installed hardware devices.  
3. In the Device Manager tab, your hardware devices  
are in alphabetical order and should include a  
Universal Serial Bus controller toward the bottom  
of the list. Double click on this device to open it.  
In order for the USB Director RS-232 and other USB  
devices to work properly, at least two devices must be  
listed under Universal Serial Bus controller in the  
Device Manager tab. Although the exact name of each  
manufacturer’s device listing can vary, the names of  
these two required USB devices should include the  
following descriptive words:  
• USB Root Hub  
• USB Host Controller  
29  
USB DIRECTORS RS-232  
If you do not see one or both of these devices, go on to  
Section 5.1.4.  
5.1.4 DETERMINING WHY SUPPORT  
IS  
NOT PRESENT  
The DETAILS button in the USBREADY program (see  
Section 5.1.2) can help you determine what is  
preventing USB support. Click on the DETAILS button  
and wait for the results. If the USB Class Host Controller  
window reads, “No USB Host Controller Found,” then  
the necessary hardware, a USB Host Controller, has not  
been detected. If your PC doesn’t have USB connectors,  
then it won’t support USB regardless of which Windows  
version it’s running. You will need to purchase a PCI  
USB controller card. If your PC does have USB  
connectors, verify that the USB hardware is enabled in  
your system BIOS configuration. If the USB Class Host  
Controller window displays any other message, such as  
“Standard,” “Intel,” “Universal,” or “Open” Host  
Controller, then hardware support is present, but an  
incompatible version of Windows is currently installed.  
If the Test Results Details dialog box shows  
Windows 95 version 4.0.1111, which is Windows 95  
OSR.2, you will need to upgrade to a more recent  
version of Windows.  
30  
CHAPTER 5: Troubleshooting  
If the Test Results Details dialog box shows  
Windows 95 version 4.0.950 or 4.0.950a, these  
Windows 95 versions do not support the upgrade path to  
USB. Unfortunately, Microsoft has not provided an  
upgrade path to OSR2 from earlier of these versions of  
Windows. OSR2 must be preinstalled by your PC vendor.  
Contact your PC vendor for more information.
