The board meets the requirements for the MD1 "Low Profile" specification as defined by PCISIG in PCI 2.2 "Low Profile Addendum." We ship each adapter with both the low profile bracket and the standard profile PCI slot bracket, offering the customer versatility in installation. The COMM+8.LPCI also features Universal Bus (3.3 and 5.0V) operation. What is Included The COMM+8.LPCI is shipped with the following items. If any of these items is missing or damaged, contact the supplier. • COMM+8.LPCI Serial I/O Adapter • Standard PCI Height bracket • Micro MDB-68 to eight DB-25 ‘Spider Cable’ P/N CA199 • Sealevel Software CD Sealevel Systems COMM+8.LPCI Page 3 Card Setup Card Setup Address and IRQ selection The COMM+8.LPCI is automatically assigned I/O addresses and IRQs by your motherboard BIOS or by a ‘Plug- n-Play’ Operating System. Adding or removing other hardware or moving the adapter to another slot may change the assignment of I/O addresses and IRQs. Baud Rates and Oscillator value The following table shows some common data rates and the rates you should choose to achieve them when using the COMM+8.LPCI. If the O/S of choice is Windows 95/98/ME/2000/NT/XP, the oscillator value (7.3728 MHz) will be automatically entered into the ‘Advanced Tab’ on 95/98/Me/2000/XP Device Manager applet. When using Windows NT, the ‘Advanced Ports’ applet in the Control Panel should be launched and the oscillator value may be entered in the ‘Advanced’ tab. When using any other OS (i.e. Linux, or QNX) the following tables should be used. For this Data Rate Choose this Data Rate 1200 bps 300 bps 2400 bps 600 bps 4800 bps 1200 bps 9600 bps 2400 bps 19.2K bps 4800 bps 57.6 K bps 14.4K bps 115.2 K bps 28.8K bps 230.4K bps 57.6 K bps 460.8K bps 115.2 K bps If your communications package allows the use of Baud rate divisors, choose the appropriate divisor from the following table: For this Data Rate Choose this Divisor 1200 bps 384 2400 bps 192 4800 bps 96 9600 bps 48 19.2K bps 24 38.4K bps 12 57.6K bps 8 115.2K bps 4 230.4K bps 2 460.8K bps 1 Sealevel Systems COMM+8.LPCI Page 4 Installation Installation Operating System Installation Windows 95/98/ME/NT/2000/XP Do not install the Adapter in the machine until the software has been fully installed. 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. The IRQ is typically selected by the BIOS or operating system. Some BIOS setup software will allow changing the IRQ, but others do not. Another method of changing assigned resources is to try changing PCI slots. This will typically cause the BIOS or OS to reassign the resources. 4. Make sure the Sealevel Systems adapter is securely installed in a motherboard 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. You can use D:\software\seacom\Other\DOS\PCI\FindPCI.exe to determine resources that have been assigned to your adapter. Make sure that if available, the ‘Use Plug-n-Play” option is turned ‘OFF’ in your BIOS. Having this option set to ‘ON’ in DOS or Windows 3.x will cause erratic operations. 6. For Windows95/98/ME/NT/2000/XP, 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. Sealevel Systems COMM+8.LPCI Page 8 Appendix B - How To Get Assistance Appendix B - How To Get Assistance 1.

Sealevel Systems COMM+8.LPCI Page 9 Appendix C - Electrical Interface 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-C/D/E or EIA/TIA-232-C/D/E. It is defined as “Interface between Data Terminal Equipment and Data Circuit- Terminating Equipment Employing Serial Binary Data Interchange”. The mechanical implementation of RS-232 is on a 25-pin D sub connector. 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 has 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 20K bps / 50 ft. The absolute maximum data rate may vary due to line conditions and cable lengths. RS-232 often operates at 38.4K bps 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. Sealevel Systems COMM+8.LPCI Page 10 Appendix D - Asynchronous Communications Appendix D - Asynchronous Communications Serial data communications implies that individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character. Data rate, error checking, handshaking, and character framing (start/stop bits) are pre-defined and must correspond at both the transmitting and receiving ends. Asynchronous communications is the standard means of serial data communication for PC compatibles and PS/2 computers. The original PC was equipped with a communication or COM: port that was designed around an 8250 Universal Asynchronous Receiver Transmitter (UART). This device allows asynchronous serial data to be transferred through a simple and straightforward programming interface. A starting bit followed by a pre-defined number of data bits (5, 6, 7, or 8) defines character boundaries for asynchronous communications. The end of the character is defined by the transmission of a pre-defined number of stop bits (usually 1, 1.5 or 2). An extra bit used for error detection is often appended before the stop bits. Idle state of Odd, Even line or Remain Idle or 5 to 8 Data Bits Unused next start bit 1 P STOP BIT 0 1 1.5 2 Figure 1 - Asynchronous Communications Bit Diagram This special bit is called the parity bit. Parity is a simple method of determining if a data bit has been lost or corrupted during transmission. There are several methods for implementing a parity check to guard against data corruption. Common methods are called (E)ven Parity or (O)dd Parity. Sometimes parity is not used to detect errors on the data stream. This is refereed to as (N)o parity. Because each bit in asynchronous communications is sent consecutively, it is easy to generalize asynchronous communications by stating that each character is wrapped (framed) by pre-defined bits to mark the beginning and end of the serial transmission of the character. The data rate and communication parameters for asynchronous communications have to be the same at both the transmitting and receiving ends. The communication parameters are baud rate, parity, number of data bits per character, and stop bits (i.e. 9600,N,8,1).
