The VERSA COMM+4.PCI allows for connection to any device utilizing the RS-232 electrical interface, such as modems, data-entry terminals, and plotters. What’s Included The VERSA COMM+4.PCI is shipped with the following items. If any of these items are missing or damaged, contact the supplier. • VERSA COMM+4.PCI Serial I/O Adapter • Cable consisting of either (1) DB-37 Female to (4) DB-25 Males (7401) or (1) DB-37 Female to (4) DB-9 Males (7401-DB9). • Serial Utility Software CD Sealevel Systems VERSA COMM+4.PCI Page 1 Card Setup Card Setup Clock Modes The VERSA COMM+4.PCI employs a unique clocking option that allows the end user to select from divide by 4, divide by 2 and divide by 1 clocking modes. This mode is selected at J2. To select the Baud rates commonly associated with COM: ports (i.e. 2400, 4800, 9600, 19.2, … 115.2K Bps), place the jumper in the divide by 4 mode (silk-screen DIV4). DIV1 DIV2 DIV4 Figure 1 - Clocking Mode ‘Divide By 4’ To double these rates up to a maximum rate for 230.4K bps, place the jumper in the divide by 2 (silk-screen DIV2) position. DIV1 DIV2 DIV4 Figure 2 - Clocking Mode ‘Divide By 2’ To select the maximum data rate (460.8K bps), place the jumper in the divide by 1 (silk-screen DIV1) position.

Sealevel Systems VERSA COMM+4.PCI Page 5 Technical Description Technical Description The VERSA COMM+4.PCI utilizes the 16C554 UART. This chip features programmable baud rate, data format, interrupt control and a 16-byte input and output FIFO, and is functionally 4 16C550 UARTs. The 16C854 UART is also available on this card, which has a 128-byte FIFO as opposed to the 16-byte FIFO available in the 16C554.

Sealevel Systems VERSA COMM+4.PCI Page 7 Appendix A - Troubleshooting Appendix A - Troubleshooting 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. 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, 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.

Return Authorization Must Be Obtained From Sealevel Systems Before Returned Merchandise Will Be Accepted. Authorization Can Be Obtained By Calling Sealevel Systems And Requesting A Return Merchandise Authorization (RMA) Number. Sealevel Systems VERSA COMM+4.PCI 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 VERSA COMM+4.PCI 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 4 - 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).
