Introduction

The ACB-ULTRA.LPCI adapter provides the PC 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 10M bps in burst mode. By utilizing the Z16C32's 32 byte FIFO buffer coupled

with 256K of on board memory, higher data rates are achieved.

The ACB-ULTRA.LPCI meets the PCISIG size requirements for an MD1 Low Profile adapter. This allows the

ACB-ULTRA.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-ULTRA.LPCI is a ‘Universal Bus’ adapter, allowing for use in either

+5 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.

Description

CA-178

6’ shielded cable with a DB-25F connector to an ITU-T ISO-2593 style connector (V.35) and converts

the Sealevel DB-25 implementation to the ITU-T V.35 mechanical standard.

CA-104

6’ extension cable with one DB-25M connector and one DB25Fconnector, pinned one-to-one, for use

with RS-232 and RS-530.

CA-107

10” shielded cabling adapter with a DB-25F (RS-530) to a DB-37M (RS-449 DTE). RS-530 is replacing

RS-449 in Telecom applications, but there is still a very large installed base of equipment that still

uses the RS-449 pin-out. Both standards use RS-422 to define the electrical specifications and are

interchangeable via this adapter cable.

CA-159

6’ shielded cable with a DB-25F (RS-530) to a DB-15M (X.21) and converts the standard DB-25

implementation of RS-530 or RS-422 to the ITU-T X.21 standard.

Software Installation

Windows 2000/XP Installation

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. Select the Part Number (5104) for your adapter from the listing. Select ‘Download Now’ for the

version of SeaMAC software (Route56 for Linux v2.0.10).

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

components. Next (depending on the OS version) select the ‘Run this program from its current

location’ or ‘Open’ option. Follow the information presented on the screens that follow.

4. A screen may appear with the declaration: “The publisher cannot be determined due to the

problems below: Authenticode signature not found.” Please select 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.

Hardware Installation

The adapter can be installed in any PCI (5V or 3.3 V) expansion slot.

Do not install the Adapter in the machine until the software has been fully installed.

1. Turn off power. Disconnect the power cord.

2. Remove the PC case cover.

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

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

5. Replace the screw. (This is required to ensure FCC Part 15 compliance.)

6. Replace the cover.

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

The ACB-ULTRA.LPCI is now ready for use.

Technical Description

The ACB-ULTRA.LPCI adapter was designed for seamless integration into any PCI based system. The ACB-

ULTRA.LPCI adapter requires a PCI slot, one IRQ, an 8 byte block of I/O address and a 16K block or 256K

block of memory address and additionally, the IUSC requires a 256 byte block of memory. The memory

range of this adapter can be configured to reside in the lower 1 Megabyte memory only or anywhere in

upper memory. Low memory (not available on PCI 2.2 or higher systems) must be configured as 16 X 16K

blocks of page memory. High memory can be configured as a 256K linear block or 16K paged memory.

Features

•Single channel high speed sync/async wide area network (WAN) interface

•RS-232, RS-422/449, EIA-530, V.35 and RS-485 serial interface capability with versatile cabling

options

•Multi-protocol capable including PPP (point-to-point protocol), Frame Relay, X.25, high-speed

Async, Bi-Sync, Mono-Sync, HDLC, SDLC, etc.

•Ideal for T1, Fractional T1, E1, and ISDN and other WAN applications

•On-board Z16C32 (IUSC™) with built in DMA controller and 32 byte FIFO buffer

•Up to 10 Mbps burst mode

•256K of on-board RAM

•Link list DMA supported

•32-bit data path

•OEM Security feature available as an option

Z16C32 IUSC™

The ACB-ULTRA.LPCI 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 256K 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. An on-board 20MHz oscillator clocks the IUSC.

Technical Description, Continued

RAM

The memory window is located by BIOS PCI setup or the Set PCI function. The window size is a 16K paged

or 256K linear block. In paged mode the registers are located in the I/O registers.

•Low Memory options: 16 pages of 16K memory blocks totaling 256K (not available on PCI 2.2 or

later systems).

•High Memory options: 16 pages of 16K memory blocks totaling 256K or one linear block of 256K

memory.

Interface Selection

The ACB-ULTRA.LPCI supports a variety of electrical interfaces. Reference the Control and Status Registers

Defined section of this manual for this bit description. There is line termination on RXD, RXC, and TXC in

the following modes: RS-530, RS-530A, RS-485T, and V.35.

Reset Circuit

Writing any value to base+3 will reset the Z16C32. Only one write is required. This starts a reset sequence,

which lasts about 320 ns. During the reset sequence base+3 bit D4 will read 0. When the reset is complete,

base+3 bit D4 will read 1.

The Z16C32 should not be accessed until the reset sequence is complete.

TSET Clock Select

Port5 of Z16C32 is used to select TSET clock source.

•0 selects 16C32 TXC as source

•1 selects received TXC as source
