Introduction

The ACB-MP+4.PCIe (Item# 5402e) is a four-port PCIe bus RS-232, RS-422, RS-485,EIA-530, EIA-530A, V.35

synchronous serial interface. Designed using the popular Zilog Z85230 Enhanced Serial Communication

Controller (ESCC), the board is an ideal solution for military, satellite, radar, banking, and other applications

that require robust synchronous communications.

For maximum flexibility, each of the serial ports can be individually configured for RS-232, RS-422, RS-

485,EIA-530, EIA-530A, V.35 communications. In RS-232 mode, all common modem control signals are

implemented for compatibility with a wide range of peripherals. A digital phase lock loop (DPLL) is included

on each port, and the board supports data rates up to 128K bps in burst mode. For easy implementation, a

fan-out cable is included that terminates the onboard 100-pin connector to four DB-25M connectors.

The ACB-MP+4.PCIe features a PCIe 1.1 interface and will operate on x1, x4, x8 or x16 PCIe Bus slots.

Software support, critical for successful synchronous communication development, is provided through

Sealevel’s SeaMAC driver. HDLC/SDLC protocols are supported as well as certain configurations of

Monosync, Bi-sync, and Raw modes.

The ACB-MP+4.PCIe also utilizes the Exar SP-506 multi-protocol electrical interface chip that allows the

ACB-MP+4.PCIe 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.

Features

•Compliant with RoHS and WEEE directives

•Each port individually configurable for RS-232, RS-422, RS-485, RS-530, RS-530A, or V.35

•Z85230 Enhanced Serial Communications Controller (ESCC)

•Data rates to 128K bps (Burst mode)

•Included fan-out cable terminates 100-pin SCSI-style connector on board to four DB-25M

connectors (Item# CA339)

Advisory Conventions

Warning

The highest level of importance used to stress a condition where damage could result to the

product, or the user could suffer serious injury.

Important

The middle level of importance used to highlight information that might not seem obvious or a

situation that could cause the product to fail.

Note

The lowest level of importance used to provide background information, additional tips, or other

non-critical facts that will not affect the use of the product.

Optional Items

Depending upon your application, you are likely to find one or more of the following items useful for

interfacing the ACB-MP+4.PCIe to real-world signals. All items can be purchased from our website

(http://www.sealevel.com) or by calling (864) 843-4343.

Cables and Converters

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

Microsoft Windows XP/Vista/Windows 7™ Operating Systems

Do not install the adapter until the software has been successfully installed.

1. Begin by locating, selecting, and installing the correct software from the Sealevel software driver

database.

2. Type in or select the part number (5402e) for the adapter from the listing. Select ‘Download Now’

for the correct version of SeaMAC software compatible with your system.

3. The setup files will automatically detect the operating environment and install the proper

components. Follow the information presented on the screens that follow.

4. 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.

5. 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.

6. The software is now installed, and you can proceed with the hardware installation.

Hardware Installation

The adapter can be installed in any x1, x4, x8 or x16 PCIe expansion slot.

Do not install the adapter until the software has been successfully installed.

1. Turn off power. Disconnect the power cord.

2. Remove the PC case cover.

3. Locate an available PCIe slot and remove the blank metal slot cover.

4. Gently insert the PCIe adapter into the slot. Make sure the adapter is seated properly.

5. Replace the screw (required for FCC Part 15 compliance).

6. Replace the cover.

7. Connect the power cord and power up the machine.

8. The ACB-MP+4.PCIe is to be installed when the system is booted.

Technical Description

The ACB-MP+4.PCIe utilizes the Zilog Z85230 Enhanced Serial Communications Controller (ESCC) and

includes a dedicated Z85230 per port. 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

85230 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. It should be noted that the Z85230 chip is manufactured in different speed ranges and installation of

a different oscillator may also require changing the Z85230.

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.
