Hardware Installation

Installing the CB Series module is easy. Before inserting the module into the PC/104-Plus slot,
you must first configure the I/O base address, interrupt vector, IRQ, and serial interface (for select
models).

ATTENTION

Safety First!
To prevent damage to your system or board, make sure your embedded PC’s power is turned off
before installing your CB Series module.

Step 1: Shut off power to your embedded PC and to any peripheral devices. After shutting off

power, remove the cover of your embedded PC.

Step 2: Use the DIP switches on the module to select the serial interface. Details for each model

are provided later in this chapter.

Step 3: Insert the module firmly into the embedded PC’s PC/104-Plus slot.

Step 4: Screw the control board in place.

Step 5: Connect the cables.

Step 6: Power on the embedded PC. The BIOS will automatically set the IRQ and I/O address

Step 7: Proceed with the software installation. Please refer to Chapter 3.

Rotary Switch

A rotary switch on the board makes it easy to set the appropriate signals, particularly when
installing multiple PC/104-Plus modules in the same unit. The rotary switch, which looks like a
clock, provides a bi-directional path with no signal pr o pagat i on del a y . The first module on the
stack should be set to CLK0, the second to CLK1, etc., to eliminate clock skew between modules.

Termination Resistor

Onboard termination resistors can be activated individually for each serial port using jumpers JP1
through JP4. JP1 corresponds to serial port 1. Short the jumper pins to activate the termination
resistor; leave the jumper pins open to bypass the termination resistor.

The following topics are covered in this chapter:

 Windows NT
 Windows 95/98/ME
 Windows Vista (32-bit and 64-bit)
 Windows XP, 2003 (32-bit and 64-bit)

CB Series PC104 Plus User’s Manual Software Installation

Windows NT

Installing the Driver

You will need to plug the board in an available PCI or PCI-X slot first, before installing the driver.
Note that these instructions use the CB-114 as an example. The procedure for installing all models

is the same.

1. Log into Windows NT as Administr ator.

2. Locate the appropriate folder for your board’s dr ivers on the Document & Software CD. The

NT drivers will be located under the product folder in the \Software\WinNT directory (e.g.,
under \CB-114 Series\Software). Copy this folder to the PC’s hard disk and remember its
location.

3. In the Control Panel, open Network applet. On the Adapters tab, click Add. When

prompted to select a product, click Have Disk….

You will be prompted to enter the path to the driver. Enter the location of the drivers that you
copied from the Document & Software CD (C:\Windows.nt in this example) and then click OK.

3-2

CB Series PC104 Plus User’s Manual Software Installation

4. When prompted, select your board model (Smartio/Industio Family multiport board in this

example) and click OK.

5. After the files have been installed, a configuration panel will open. This is where boards are

installed, configured, and removed. If another board has already been installed on the system,
it will already be listed. Windows NT does not automatically detect Moxa UPCI boards, so
you will need to click Add for a newly installed board.

6. Under Board Type, select the UPCI board that is being installed. The window will show the

COM settings for the serial ports on the board. You can modify the COM settings for any port
at this time by selecting a port and clicking Port Setting. If you are satisfied with the COM
settings, click OK to return to the configuration panel.

3-3

CB Series PC104 Plus User’s Manual Software Installation

7. The board will now appear in the configuration panel (CB-114 Series in this example). Click

OK to return to the Network applet. After that, click OK again to exit the Network applet

8. Restart the PC. After you have logged back into Windows NT, you may check the event log

issued by the Moxa driver to see if the board’s ports have been initialized successfully. In the
Administrative group, open Event Viewer and select Log and System. For each newly
installed or configured Moxa UPCI board, check for a message stating that the board has been
enabled (e.g., “MoxaCB-114 board, wit h first serial port COM3, has been enabled”).

3-4

CB Series PC104 Plus User’s Manual Software Installation

Configuring the Ports

1. In Windows Control Panel, open the Network applet. In the Adapters tab, UPCI boards will

appear as a type of Moxa adap ter (MOXA Smartio/Industio Family Adapter in this
example). Select the Moxa adapter and click Properties….

2. The configuration panel will open with a list of installed boards. Select your board and click

Property. Up to 4 Moxa UPCI boards can be installed at a time.

3-5

CB Series PC104 Plus User’s Manual Software Installation

3. Select a port to configure and click Port Setting.

Under Port Number, select a COM number to assign to the serial port. Select Auto Enumerating
COM Number to map subsequent ports in numerical order. For example, if COM 3 is assigned to
Port 1, then COM 4 will be automatically assigned to Port 2.

4. Select an Rx FIFO Trigger and Tx FIFO Size. The default Rx FIFO Trigger is 120 bytes

(high level). The default Tx FIFO Size is 128 bytes (high level). Select Set the change to all
ports to use this setting for all serial ports on the board.

TxFIFO RxFIFO
High 128 120
Middle 64 60
Low 1 1

CB Series PC104 Plus User’s Manual Software Installation

5. Click OK to approve the settings for the selected port. Continu e in the same way to configure

the other ports. When you have finished setting up the ports, click OK to close the Properties
window and apply the new port settings. Click OK again to exit the Network applet.

Removing the Board

To remove a board, shut of your PC and physically remove the board from the PCI slot. The next
time you start up the PC, Windows NT will automatically remove the configuration. You do not
need to go through the Windows control panel.

Updating the Driver

1. In Windows Control Panel, open the Network applet. In the Adapters tab, UPCI boards will

appear as a type of Moxa adap ter (MOXA Smartio/Industio Family Adapter in this
example). Select the Moxa adapter and click Remove.

3-7
