Introduction

Overview

Congratulations! You have now entered the world of mobile communications via the Sealevel Systems PC-SIO-232 Serial Interface.

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-SIO-232 continues the Sealevel Systems tradition of an easy to use, highly reliable, and technically advanced serial I/O solution.

What’s Included

The PC-SIO-232 is shipped with the following items. If any of these items are missing or damaged, contact the supplier.

Card Setup

Card and Socket Services must be loaded on the system prior to installing the PC-SIO-232 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/ME/2000/XP).

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-SIO-232, the generic Card Services driver supplied with the computer system should provide adequate support for most applications. A DOS ‘Enabler’ is also provided for older systems in which the Generic Enabler isn’t adequate. Please refer to Appendix C for information on the SEAPC enabler and the diagnostic tool SSEnable.

Connecting the PC-SIO-232 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-SIO-232 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-SIO-232 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.

Technical Description

The PC-SIO-232 provides one RS-232 serial port utilizing the 16550 UART (Universal Asynchronous Receiver Transmitter).

The PC-SIO-232 is addressable as any COM: port (e.g. COM1:, COM2:, etc.) The PC-SIO-232 provides for selectable IRQs (3,4,5,7,9,10,11,12,15). I/O address and IRQ combinations are very flexible, and information on selecting these combinations is available in the Card Services Documentation and the supplied software. Please refer to the software supplied with the PC-SIO-232 for any manual updates, corrections and software specific changes

Each COM: Port requires a minimum of one block of eight I/O addresses. For example, COM1: is usually hex address 3F8. 3F8 is the base address, and the COM: ports extend through 3FF. In most applications, each COM: port will utilize one IRQ.

Connector Pin Assignments for RS-232 (DB-25 and DB-9 Male)

Signal Name DB-25 DB-9* Mode

GND Ground 7 5 TD Transmit Data 2 3 Output RTS Request To Send 4 7 Output DTR Data Terminal Ready 20 4 Output RD Receive Data 3 2 Input CTS Clear To Send 5 8 Input DSR Data Set Ready 6 6 Input CD Carrier Detect 8 1 Input RI Ring Indicator 22 9 Input

* Note: These assignments meet EIA/TIA/ANSI-574 DTE for DB-9 type connectors. Technical Note: Please terminate any control signals that are not going to be used. The most common way to do this

is connect RTS to CTS and RI. Also, con nect DCD to DTR and DSR. Terminating these pins, if no t used, will help insure you get the best performance from your adapter.

Appendix A - Troubleshooting

Appendix A - T roubleshooting

Sealevel Software is supplied with the Sealevel Systems adapter and may be used in the troubleshooting procedures. Using this software and following these simple steps can eliminate most common problems without the need to call Technical Support.

1. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller

cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if any) should be identified.

2. Configure your Sealevel Systems adapter so that there is no conflict with currently installed adapters. No two

adapters can occupy the same I/O address.

3. Make sure the Sealevel Systems adapter is using a unique IRQ. While the Sealevel Systems adapter does allow

the sharing of IRQs, many other adapters (i.e. SCSI adapters & on-board serial ports) do not

4. Make sure the Sealevel Systems adapter is securely installed in the PC Card Slot.

5. When running DOS or Windows 3.x refer to the supplied Sealevel Software and this User Manual to verify that

the Sealevel Systems adapter is configured correctly. This software contains a diagnostic program ‘SSD’ (D:\software\seacom\Other\DOS\DIAG, where D: = the driver letter of your CDROM drive) will verify if an adapter is configured properly. This diagnostic program is written with the user in mind and is easy to use

6. For Windows95/98/ME/NT/2000, the diagnostic tool ‘WinSSD’ is installed in the SeaCOM folder on the Start

Menu during the setup process. First find the ports using the Device Manager, then use ‘WinSSD’ to verify that the ports are functional.

7. Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This will eliminate any

software issues from the equation.

Appendix C - Electrical Interface

RS-232

Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and revised several times and is often referred to as RS-232 or EIA/TIA-232. The IBM PC computer defined the RS-232 port on a 9 pin D sub connector and subsequently the EIA/TIA approved this implementation as the EIA/TIA-574 standard. This standard is defined as the 9-Position Non-Synchronous Interface between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange. Both implementations are in wide spread use and will be referred to as RS-232 in this document. RS-232 is capable of operating at data rates up to 20 Kbps at distances less than 50 ft. The absolute maximum data rate may vary due to line conditions and cable lengths. RS-232 often operates at 38.4 Kbps over very short distances. The voltage levels defined by RS-232 range from -12 to +12 volts. RS-232 is a single ended or unbalanced interface, meaning that a single electrical signal is compared to a common signal (ground) to determine binary logic states. A voltage of +12 volts (usually +3 to +10 volts) represents a binary 0 (space) and -12 volts (-3 to -10 volts) denote a binary 1 (mark). The RS-232 and the EIA/TIA-574 specification define two types of interface circuits, Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE). The Sealevel Systems adapter is a DTE interface.
