The VScom H-Series PCI controller offers a compact, low power, set of additional interfaces. All serial ports are built by 16950A-compatible UARTS with 128 byte FIFO. On some cards there are four speed modes available, from "x1 (Compatibility)" upto "x8 (Enhanced)".
The VScom n10H PCI cards (n=1,2,4) offer an additional parallel port. It supports SPP, NIBBLE, PS2 and EPP modes.
 

1. With some products of the H-series, there is one jumper for speed setting. It is located near the crystal, and named JP1.

You need to have administrator privileges to install any new drivers under Windows NT 4.0. To install the driver or update the configuration please log on to Windows NT 4.0 as "Administrator" or ask your system administrator to install the VScom H-series PCI card and driver. Please proceed with the following steps to install the driver:

1. Switch on the computer and start Windows NT 4.0.
2. Insert the supplied CD-ROM into the drive.
3. If your system is configured for Auto-start of CD-ROM, go to the products page, find your product and select driver. You'll find a link to the NT4 drivers directory.
4. Otherwise double click on "My Computer", and choose CD-ROM drive (D:)
5. Double Click "WinNT4".
6. Double Click "PCI_Driver".
7. Double click "install.exe".
8. Install.exe starts and requests confirmation of installation. You may change the target directory for the software. If there is a space in the name, please use the short name (e.g. PROGRA~1) instead.
9. Click Yes, and Reboot when requested.
10. Log on to NT as "Administrator" again. The "A new VScom Card was found." dialogue appears. Click "Configure".
11. The next panel shows the detected hardware. Click on "OK".

Checking installation
You can now verify the installation by looking at the "Administrative Tools" section of the "Windows NT Diagnostics (also called WinMSD" (Go there by Start - Setting - Windows NT Diagnostics - Administrative Tools - Resources). There you will find new device "vscnt" listed.
Double click on it, you will see the IRQ and I/O information.
Click on the right tab, you can see all the detailed information of IRQ, Input/Output & Memory Range used by PCI Ports.
Open "VScom PCI" in the control panel (Go there by Start - Setting - Control panel). Open "VS Cards" and double click on the detected controller to open the properties. In the "advanced" tab, click the button to verify the speed setting from the hardware installation.
You may also rename the serial and parallel ports here.

To Uninstall Driver
To remove installed files and Windows registry information

1. Go to the Control Panel.
2. Open the "Add/Remove programs" applet.
3. Select "Vscom drivers for ...".
4. Click "Remove".
5. "VScom install" requests to confirm the uninstall, Click "Yes".
6. Reboot the computer when requested.

1. The board is not found during or after installation
   

   -	The card is not seated properly in the PCI slot. Re-install the card in the PCI slot.

2. Made wrong selection of "Cancel" during installation. When re-install the driver Windows 95/98/2000 doesn't detect the card.
   

   -	The driver installation is not complete. Install the card in another PCI slot to initialize the installation again.

3. During installation, NT4.0 shows blue screen (white-text-on-blue-background)
   

   -	In most cases, there is an IRQ conflict. The IRQ assigned to the board is in conflict with other devices. The VScom PCI driver supports IRQ sharing. However, some devices like network card or SCSI controller don't share IRQ with other devices.
   -	Be sure that your system has a free IRQ for the card. Enter "BIOS setup - PCI configuration", and set all IRQs to "PCI/ISA PnP" except for those non-PnP ISA components. This will bring up the maximum number of free IRQs in the system.
   -	Try to install the card to another PCI slot. To install the VScom PCI card to a different PCI slot will get a different IRQ assignment. Or, you can exchange the PCI slot with another card.

4. In the Event Viewer, error message shows "Another driver on the system, which did not report its resources, has already claimed the interrupt used by LPTx"
   

   -	please refer to symptom (3) about the IRQ conflict problem, and the solution.

5. Printer works fine, but scanner does not work (VScom n10H PCI)

   -	Some scanners will not work if the printer port IRQ is other than IRQ5 or IRQ7. You can reserve the IRQ5 or IRQ7 from the BIOS setting to specific PCI slot, and install the PCI parallel card to that PCI slot to get the required IRQ.
   -	The VScom n10H PCI parallel port is compatible with most devices. However, some models of printers and scanners, e.g. HP5100C, only work with onboard parallel port LPT1 at address of 378h. Since these type of devices only talk to the onboard chip, you need to connect to the onboard LPT1 for these type of printes or scanners.

6. Cannot use ZIP drive in Windows 95/98
   

   -	The parallel port is not located at address 278h or 378h. Remap the address of the parallel port to 278h or 378h (recommended).

7. Sound card or Modem does not function after installation of the PCI parallel card.

   -	The address of 278h has a contention with ISA PnP bus enumeration. Enter the BIOS setup, and set the onboard parallel port to 278h. Install the PCI parallel port to get another printer port address to avoid conflict.
