Introduction
The Sealevel ACB-ULTRA.LPCIe (Item# 5104e) is a PCI Express 1.0a compliant interface adapter with a
single channel high-speed multi-protocol serial interface suitable for the most popular communication
protocols. This sync/async card provides an ideal solution for high-speed applications including LAN/WAN
connectivity. Utilizing the Zilog Z16C32 (IUSC™) on chip DMA controller eliminates bus bandwidth
constraints that are placed on typical interface adapters, allowing data rates to reach 10Mbps in burst
mode. By utilizing the Z16C32's 32 byte FIFO buffer coupled with 256KB of on board memory, higher data
rates are achieved.
The ACB-ULTRA.LPCIe ships with a Low Profile PCIe bracket that will only work in a Low Profile PCIe slot.
If you need a standard size PCIe bracket, please order Item# 5104eS.

Installation & Configuration
Software Installation
Windows Installation
This section contains helpful information pertaining to the installation of supported Sealevel Systems, Inc.
software packages. First, the process of acquiring the software is discussed. Next, the installation is
detailed in a step-by-step guide for Windows operating systems.
Where to Get Sealevel Software
The current versions of Sealevel software packages can be obtained from the Sealevel website (see
following instructions). If you already have the Sealevel software, proceed to the installation section.
Do not connect the hardware until the software has been successfully installed.
To install Sealevel software, you must log in as an administrator or have administrator privileges.
Only users running Windows 7 or newer should utilize these instructions for accessing and installing
the appropriate driver via Sealevel’s website. If you are utilizing an operating system prior to
Windows 7, please contact Sealevel by calling 864.843.4343 or emailing [e-mail] to
receive access to the proper driver download and installation instructions.
1. Begin by locating, selecting, and installing the correct software from the Sealevel software
driver database.
2. Type in or select the part number (#5104e) for the adapter from the listing.
3. Select ‘Download file’link for SeaMAC for Windows.
4. The setup files will automatically detect the operating environment and install the proper
components. Follow the information presented on the screens that follow.
5. A screen may appear with text similar to: “The publisher cannot be determined due to the
problems below: Authenticode signature not found.” Please click the ‘Yes’ button and
proceed with the installation. This declaration simply means that the operating system is
not aware of the driver being loaded. It will not cause any harm to your system.

6. During setup, the user may specify installation directories and other preferred
configurations. This program also adds entries to the system registry that are necessary
for specifying the operating parameters for each driver. An uninstall option is also included
to remove all registry/INI file entries from the system.
7. The software is now installed, and you can proceed with the hardware installation.
Upgrading to the current SeaMAC driver
1. Download the current driver using the instructions from the Where to Get Sealevel Software section
above. Please take note of the destination directory for download.
2. Follow the instructions in the subsequent section named Remove Hardware Using Device Manager.
3. Launch the SeaMAC installer executable from the directory where it was downloaded.
4. When the InstallShield Wizard’ window appears, click the ‘Next’ button to initiate the software
installation.
5. When the ‘License Agreement’ window appears, accept the terms, and click ‘Next’ to continue. You
can click the ‘Print’ button to print out a copy of the agreement for your records. If you do not accept
the terms of the agreement, the wizard will stop.
6. When the ‘Ready to Install the Program’ window appears, click the ‘Install’ button to install the
software onto the hard drive of your computer. Some versions of Windows will halt the installation
and provide you with a dialog box which will ask you for permission for the installer to make
changes to your computer. Click on the button to continue installation of your Sealevel software.
7. If prompted, reboot your computer for changes to take effect.
Hardware Installation
Do not install the PCI Express board until the software has been successfully installed.
Once you have installed the software, install the 5104e into an available PCI Express slot and boot the
computer. The drivers that were installed during the software installation process will automatically be
used to configure the adapter
Once the hardware installation completes, you may need to restart the computer to finalize the
installation process.

Technical Description
The Sealevel ACB-ULTRA.LPCIe (Item# 5104e) is a PCI Express 1.0a compliant interface adapter with a
single channel high-speed multi-protocol serial interface suitable for the most popular communication
protocols. This sync/async card provides an ideal solution for high-speed applications including LAN/WAN

constraints that are placed on typical interface adapters, allowing data rates to reach 10Mbps in burst
mode. By utilizing the Z16C32's 32 byte FIFO buffer coupled with 256KB of onboard memory, higher data
rates are achieved.
Z16C32 IUSC™
The ACB-ULTRA.LPCIe is based on a single Zilog Z16C32 IUSC (Integrated Universal Serial Controller). The
IUSC has a built-in DMA controller that allows high-speed data transfers directly to and from the 256KB
block of on-board memory. The IUSC’s built-in DMA controller supports 4 different modes of DMA transfer:
Single Buffer, Pipelined, Array, and Link List.
RAM
The ACB-ULTRA.LPCIe provides 256KB of onboard memory.
Interface Selection
The ACB-ULTRA.LPCIe supports a variety of electrical interfaces: RS-232, RS-422/449, EIA-530, V.35 and
RS-485. There is line termination on RXD, RXC, and TXC in the following modes: RS-530, RS-530A, RS-485T,
and V.35.
Clocking
The ACB-ULTRA.LPCIe has an on-board 20MHz oscillator that clocks the IUSC. Other oscillator frequencies
may be specified, via factory configuration: contact Sealevel for more information on this option.
OEM Security Feature (Option)
The ACB-ULTRA.LPCIe supports an OEM Security Feature, via factory configuration: contact Sealevel for
more information on this option.
25 Pin Connector Signal Layouts (DB-25 Male)
In all modes, Pin 1 has a 1K ohm resistor to GND and pin 25 has a 1K ohm resistor to +5V connection. This
is useful for RS-485 biasing. If this presents a problem in your implementation, please contact Sealevel for
aid in removing these or to inquire about an alternate factory configuration.

The RX+/- lines do not have pull up or pull down biasing. For high baud rates or long distances,
you may need to implement bias for the RX+/- lines. To do this, add connections of the RX+ pin to
pin 25, and the RX- pin to pin 1. Alternatively, add a 1K Ω resistor from the RX- pin to the GND pin,
and a 820 Ω resistor from the RX+ pin to the +5V pin of DTR. Do not toggle DTR or the bias will be
lost.
