1.0 Introduction
----------------
Service Pack 2 for the DHX Driver Suite 4.30 installs the 
latest updates to all currently installed DHX driver products
version 4.30.00 and 4.30.01 (SP1). Since SP2 includes all SP1
updates, there is no need to install SP1 prior to installing SP2.

2.0 What’s in Service Pack 2?
-----------------------------
The following sections list all SP2 updates to the individual DHX
driver products.

2.1 DHX Driver - Windows 9x
---------------------------
*  Some components have been updated to ensure consistency among
   all DHX driver products.

2.2 DHX Driver - Windows NT/2000
--------------------------------
*  Support for the new 5136-SD-PCI adapter card from SST has been
   added.

*  Dual interface mode support for all 5136-SD cards from SST
   (ISA and PCI versions) has been added. The dual interface mode
   allows the DHX Driver to run concurrently with RSLinx (or other
   third-party device drivers) on a single 5136-SD card (see the
   1784-KT Emulation in the help file).

*  Help file (including the PDF version) has been updated to cover
   the above additions.

*  Some components have been updated to ensure consistency among
   all DHX driver products.

2.3 Ethernet DHX Driver - Windows NT/2000
-----------------------------------------
*  Some components have been updated to ensure consistency among
   all DHX driver products.

2.4 Serial DHX Driver - Windows NT/2000

   all DHX driver products.

2.5 Remote DHX Driver - Windows 9x/NT/2000
------------------------------------------
*  Some components have been updated to ensure consistency among
   all DHX driver products.

2.6 Virtual DHX Driver - Windows 9x/NT/2000
-------------------------------------------
*  The "SLC-500 Advanced Programming Software" communication error,
   identified by the "MESSAGE TIMEOUTS - LOSS OF COMMUNICATIONS"
   message, has been corrected.

*  Some components have been updated to ensure consistency among
   all DHX driver products.

3.0 Who should install Service Pack 2?
--------------------------------------
Service Pack 2 installs the latest updates to all currently
installed DHX driver products version 4.30. Therefore, we strongly
recommend installing this service pack.

However, the SP2 updates to some of the DHX products are very minor
and may not warrant an upgrade. To help you decide whether you
should install this service pack, we assembled the following
product list. If you are using a product that is on this list, we
strongly recommend installing the service pack.

3.1 Systems with SP1 installed
------------------------------

    DHX Driver (Windows NT/2000)
    Virtual DHX Driver (Windows 9x/NT/2000)

3.2 Systems without SP1 installed
---------------------------------

    DHX Driver (NT/2000)
    Ethernet DHX Driver (Windows NT/2000)
    Virtual DHX Driver (Windows 9x/NT/2000)

4.0 Installing Service Pack 2
-----------------------------
To have the latest updates, install this service pack whenever a
DHX Driver product is installed or re-installed from the original
DHX Driver Suite 4.30.00 CD. For proper operation, all DHX Driver
products should always be at the same version level.

To install SP2, run Setup.exe from the base directory.

The installation program will automatically locate all DHX Driver
products version 4.30.xx on your system and apply the updates.

5.0 Re-installing Service Pack 2
--------------------------------
This service pack can be re-installed even if it has already been
installed.

To have the latest updates, re-install this service pack whenever
a DHX driver product is installed or re-installed from the
original DHX Driver Suite 4.30.00 CD. For proper operation, all
DHX driver products should always be at the same version level.

6.0 Removing Service Pack 2
---------------------------
There is no uninstall option for this service pack. In order to
revert back to the original version 4.30.00, all DHX Driver
products must be re-installed from the original DHX Driver Suite CD.

4.30.01>
4.30.01>1.1 Windows NT/9x

4.30.01>Under Windows NT 4.0 and Windows 95/98, SP1 adds the latest updates
4.30.01>to the DHX driver products. However, SP1 does not add new features
4.30.01>or functionality.
4.30.01>
4.30.01>
4.30.01>1.2 Windows 2000
4.30.01>----------------
4.30.01>Under Windows 2000, in addition to installing regular updates, SP1
4.30.01>adds Plug-and-Play (PnP) support to the DHX Driver. Specifically,
4.30.01>support for the 1784-PCMK, 1784-PCMK Series B (PCMCIA), 1784-PKTX/A,
4.30.01>1784-PKTXD/A (PCI) cards has been added.
4.30.01>
4.30.01>2.0 What’s in Service Pack 1?
4.30.01>-----------------------------
4.30.01>The following sections list all SP1 updates to the individual DHX
4.30.01>driver products.
4.30.01>
4.30.01>2.1 DHX Driver - Windows NT/9x
4.30.01>------------------------------
4.30.01>*  No functional changes. Some components have been updated to
4.30.01>   ensure consistency among all DHX driver products.
4.30.01>
4.30.01>2.2 DHX Driver - Windows 2000
4.30.01>-----------------------------
4.30.01>Windows 2000 introduced a number of architectural changes compared
4.30.01>to its predecessor, Windows NT 4.0. One of the major changes is the
4.30.01>introduction of the Windows Driver Model (WDM) for kernel mode
4.30.01>device drivers. This new model, based on the original Windows NT
4.30.01>driver model, introduces a number of new features, like Plug and
4.30.01>Play and Power Management support, which Windows NT 4.0 drivers
4.30.01>do not support.
4.30.01>
4.30.01>The DHX Driver 4.30.00 was designed for Windows NT 4.0. However,
4.30.01>since Windows 2000 provides backward compatibility for Windows NT
4.30.01>drivers, the DHX Driver, in most cases, operates fine on a Windows
4.30.01>2000 system. Specifically, all ISA bus adapter cards (like 1784-KT)
4.30.01>operate correctly. Unfortunately, Windows NT 4.0 support for the
4.30.01>PCMCIA cards is incompatible with Windows 2000. Therefore, all
4.30.01>PCMCIA cards (1784-PCMK, 1784-PCMK Series B) would not operate in
4.30.01>a Windows 2000 system. To remedy the situation, SP1 adds PnP
4.30.01>support for the PCMCIA cards. It also upgrades support for the PCI
4.30.01>cards (1784-PKTX/A and 1784-PKTXD/A) to the full Windows 2000 WDM
4.30.01>compliance.
4.30.01>
4.30.01>The following lists all SP1 updates to the DHX Driver under
4.30.01>Windows 2000:
4.30.01>
4.30.01>*  Plug-and-Play support for 1784-PCMK, 1784-PCMK Series B (PCMCIA),
4.30.01>   1784-PKTX/A and 1784-PKTXD (PCI) cards under Windows 2000 has
4.30.01>   been added.
4.30.01>
4.30.01>*  The help file (including the PDF version) has been updated to
4.30.01>   cover the new Plug-and-Play support under Windows 2000.
4.30.01>
4.30.01>*  Some cosmetic changes (improved messages) in the configuration
4.30.01>   editors.
4.30.01>
4.30.01>2.3 Ethernet DHX Driver - Windows NT/2000
4.30.01>-----------------------------------------
4.30.01>*  Added support for large PLC5 typed-write unsolicited messages.
4.30.01>
4.30.01>*  Fixed a problem with the handling of PLC5 typed-write unsolicited
4.30.01>   messages sending ASCII data.
4.30.01>
4.30.01>*  Some components have been updated to ensure consistency among all
4.30.01>   DHX driver products.
4.30.01>
4.30.01>2.4 Remote DHX Driver - Windows 9x/NT/2000
4.30.01>------------------------------------------
4.30.01>*  No functional changes. Some components have been updated to
4.30.01>   ensure consistency among all DHX driver products.
4.30.01>
4.30.01>2.5 Virtual DHX Driver - Windows 9x/NT/2000
4.30.01>-------------------------------------------
4.30.01>*  No functional changes. Some components have been updated to
4.30.01>   ensure consistency among all DHX driver products.
4.30.01>
4.30.01>3.0 Who should install Service Pack 1?
4.30.01>--------------------------------------
4.30.01>Service Pack 1 installs the latest updates to all currently
4.30.01>installed DHX driver products version 4.30. Therefore, we strongly
4.30.01>recommend installing this service pack.
4.30.01>
4.30.01>Some of the SP1 updates to some of the DHX products are strictly
4.30.01>cosmetic and may not warrant an upgrade. However, if you are using
4.30.01>or planning on using PnP cards (PCMCIA and PCI) under Windows 2000,
4.30.01>we strongly recommend installing the service pack. Also, if you are
4.30.01>using the Ethernet DHX Driver, you should install the service pack.
4.30.01>
