Introduction
Introduction
Overview
In the last few years, the portable and notebook market has grown by leaps and bounds. Most early laptops and
notebooks handled I/O expansion through proprietary expansion slots. These slots provided limited expansion for
specific peripherals such as modems and FAX peripherals. Mass storage peripherals were factory installed and
could not be easily changed. Interconnectivity through local area networks offered limited performance through
slow parallel port network interfaces.
During this time period two standards organizations, JEIDA and PCMCIA, were working on the standardization of
memory IC cards. These cards were designed as strictly non-volatile silicon storage. JEIDA was the first to propose
the 68-pin connector standard for memory cards. In 1989, PCMCIA adopted the JEIDA 68 pin standard and worked
with JEIDA on further developments.
As the notebook market grew, the need for a standard I/O bus was seen. The PCMCIA groups saw an opportunity to
meet this need with an expanded version of the 68-pin interface. Further development occurred and within one year,
release 2.0 of the standard was completed. Release 2.0 was a major update to Release 1.0 and included full
hardware support for I/O devices. Release 2.0 coincided with JEIDA’s 4.1 release and is identical.
The PC-ACB.MP adapter provides your portable PC with a single channel multi-protocol serial interface utilizing
the Zilog Z85233 (ESCC™), which is suitable for the most popular communication protocols including
HDLC/SDLC, X.25, Bi-Sync, Mono-Sync, and asynchronous.
The PC-ACB.MP utilizes the Sipex-505 multi-protocol electrical interface chip that allows the PC-ACB.MP to be
compliant with EIA/TIA-530/530A, EIA/TIA-232E, EIA/TIA-485, and ITU V.35.
What’s Included
The PC-ACB.MP is shipped with the following items. If any of these items are missing or damaged, contact the
supplier.
• PC-ACB.MP PCMCIA Serial Interface Adapter
• DB-25 cable assembly
• Loopback Plug
• Impact Resistant Carrying Case (Jewel Case)
• Sealevel Software

Installation
Installation
Card and Socket Services must be loaded on the system prior to installing the PC-ACB.MP card. Card and Socket
Services are supplied by the PCMCIA slot provider (i.e. the computer manufacturer or the PC adapter
manufacturer). These may be in the form of a third party add-on Card and Socket service (e.g. CardSoft’s
CardWizard) or with your current operating system (e.g. Windows 95/98/NT/2000).
Socket Services are the lowest level of the PCMCIA Software hierarchy. Socket Services provide a standard
interface to the higher-level drivers and isolate the socket controller’s specific hardware details. Socket Services
provide the ‘BIOS’ interface to the socket controller hardware. Socket Services are typically hidden under Card
Services and are rarely directly accessible by application software.
Card Services provide the interface to application software and drivers. Card Services are responsible for allocating
card resources and ensuring that card resources do not interfere with other existing system resources. Card Services
are typically implemented as a driver. Almost all PCMCIA type cards require some sort of software driver. In the
case of the PC-ACB.MP, the generic Card Services driver supplied with the computer system should provide
adequate support for most applications.
Connecting the PC-ACB.MP to the computer requires no special technical skills. In fact it is usually done in as
simple as two steps:
1. Follow the directions given for your operating system found on the supplied software.
2. Simply slide the card into a PCMCIA Type II compliant slot on the personal computer. The PCMCIA slot
is keyed so that the PC-ACB.MP cannot be installed backwards or upside down. The card should install
with a minimal amount of pressure. Do not force the card into the slot. Forcing the card can result in
damage to the PC-ACB.MP or to the PCMCIA slot. After the card has been installed into the PCMCIA
slot, the I/O cable should be connected to the card. The cable is also keyed to prevent it from being
installed incorrectly.
3. For Windows users that are using Sealevel’s SeaMAC software please note that there is a different install
for this card than the normal SeaMAC software. When choosing to install the software from the CD scrool
down to the SeaMAC drivers. You should see:* Note: If you are installing Part# 3612 or 5102, click
here to install the Windows 2000 interrupt mode HDLC/SDLC driver. To install the Windows NT
interrupt mode Async driver and for all other ACB products, click the "install SeaMAC" button
below. Please be sure to follow these steps for a successful installation.
Installation is complete.
The PC-ACB.MP has a number of cabling options available. These options include:
• CA-103 - This cable provides a high quality shielded cable with th e V.35 mechanical specification met on one
end and a DB-25S (female) on the other end. V.35 has a mechanical specification that is impossible to place on
a PC bracket and requires this adapter cable.
• CA-104 - This cable provides a 6’ extension for use with RS-232, and RS-530/530A.
• CA-107 - RS-530 (DB-25P) to RS-449 (DB-37P) cabling adapter. RS-530 is replacing RS-449 in Telecom
applications, but there is still a very large base of installed equipment that uses the RS-449 pin-out. Both
standards use RS-422 to define the electrical specifications and are interchangeable via this adapter cable.

Technical Description
Technical Description
The PC-ACB.MP utilizes the Zilog 85233 Enhanced Serial Communications Controller (ESCC). This chip features
programmable baud rate, data format and interrupt control. Refer to the ESCC Users Manual for details on
programming the 85233 ESCC chip.
Features
• One channel of synchronous or asynchronous communications using the Zilog Z85233 chip
• Programmable electrical interface selection EIA/TIA-232/530/530A/485 and ITU V.35
• Programmable options for Transmit clock as input or output
• Software programmable baud rate
Internal Baud Rate Generator
The baud rate of the ESCC is programmed under software control.
Control and Status Registers Definition
The control and status registers occupy 16 consecutive locations. The following tables provide a functional
