Introduction
The ACB-MP.LPCI adapter provides the PC with a single channel multi-protocol synchronous serial
interface utilizing the Zilog Z85230 (ESCC™), which supports the HDLC/SDLC protocol using the Sealevel
SeaMAC V4 device driver. SeaMAC V4 also supports certain configurations of monosync, bisync, external
sync, and raw modes. The ACB-MP.LPCI adapter is an ideal solution for applications including DDS (digital
data service), military applications, banking communications, and other specialized applications.
The ACB-MP.LPCI also utilizes the Sipex-506 multi-protocol electrical interface chip that allows the ACB-
MP.LPCI to be compliant with EIA/TIA-530/530A, EIA/TIA-232E, EIA/TIA-485, and ITU V.35. Optional cables
are available to connect RS-449, RS-530, RS-530A, V.35 and X.21 interfaces.
The ACB-MP.LPCI meets the PCISIG size requirements for an MD1 low profile adapter. This allows the ACB-
MP.LPCI to be used in a variety of modern systems, including low profile servers, network appliances and
‘All in One’ desktop computers. A standard height bracket is available for implementations in a standard
height PCI slot. The ACB-MP.LPCI is a ‘Universal Bus’ adapter, allowing for use in either +5V or +3.3V PCI
slots and provides compliance with the PCISIG PCI Bus Specification Revision 2.2/2.3, which requires ATX
power support for both 5V and 3.3V.

Optional Items
Depending upon your application, you are likely to find one or more of the following items useful for
interfacing the ACB-MP.LPCI to real-world signals. All items can be purchased from our website
(http://www.sealevel.com) or by calling 864-843-4343.
DB25 Female to DB25 Male Extension Cable, 72 inch Length (Item# CA104)
The CA104 is a standard DB25F to DB25M serial extension
cable. Extend a DB25 cable or locate a piece of hardware where
it is needed with this six foot (72 inch) cable. The connectors
are pinned one-to-one, so the cable is compatible with any
device or cable with DB25 connectors. The cable is fully
shielded against interference and the connectors are molded to
provide strain relief. Dual metal thumbscrews secure the cable
connections and prevent accidental disconnection.
Recommended for applications with data rates less than 1M
bps.
DB25 Female (RS-530) to DB37 Male (RS-449 DTE) Cable, 10 inch Length (Item# CA107)
DB25 Female (RS-530) to DB37 Male (RS-449 DTE) Cable, 10
inch Length. RS-530 was designed to replace the bulky DB37
RS-449 connector. The CA107 cable allows any Sealevel RS-530
adapter to be used in an RS-449 application.
DB25 Female (RS-530) to DB15 Male (X.21) Cable, 72 inch Length (Item# CA159)
DB25 Female (RS-530) to DB15 Male (X.21) Cable, 72 inch
Length. Converts the Standard DB25 implementation of RS-530
or RS-422 to the ITU-T X.21 standard pinout.
DB25 Female to DB25 Male (RS-530) Twisted Pair Serial Cable, 72 inch Length (Item#
CA174)
DB25 Female to DB25 Male Twisted Pair Serial Cable, 72 inch
Length. Twisted Pairs provide increased data integrity in high-
speed serial applications. Recommended for RS-530
applications with data rates greater than 1M bps.
DB25 Female (V.35) to ITU-T ISO-2593 Style Connector (V.35) Cable, 72 inch Length
(Item# CA178)
DB25 Female (V.35) to ITU-T ISO-2593 Style Connector (V.35)
Cable, 72 inch Length. The CA178 converts the Sealevel DB25
implementation of V.35 to the ITU-T V.35 mechanical
standard.

Installation & Configuration
Software Installation
Windows Installation
Do not install the Adapter in the machine until the software has been fully installed.
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
[email protected]om 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 (#5102) for the adapter from the listing.
3. Select “Download Now” 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.
For additional software support, please call Sealevel Systems’ Technical Support, [phone]. Our
technical support is free and available from 8:00 AM - 5:00 PM Eastern Time, Monday through Friday. For
email support contact: supp[email protected].

Technical Description
The ACB-MP.LPCI utilizes the Zilog 85230 Enhanced Serial Communications Controller (ESCC). This chip
features programmable baud rate, data format and interrupt control. Refer to the ESCC User Manual,
available from Zilog, for details on programming the Z85230 ESCC chip in the event you are writing your
own driver as opposed to using the SeaMAC driver.
Internal Baud Rate Generator
The baud rate of the ESCC is programmed under software control. The standard oscillator supplied with
the board is 7.3728 MHz. However, other oscillator values can be substituted to achieve different baud
rates.
Control and Status Registers Definition
The control and status registers occupy 16 consecutive I/O locations. The following tables provide a
functional description of the bit positions. This table is provided for users that desire to write their own
driver.
