Introduction Introduction Overview The Sealevel COMM+232.PCI is a two channel PCI Bus serial I/O adapter for the PC and compatibles. It provides two RS-232 serial ports supporting data rates up to 460.8K bps. The COMM+232.PCI works seamlessly with the standard operating system serial driver. UART upgrades are available providing 32. 64 and 128 byte FIFOs. What’s Included The COMM+232.PCI is shipped with the following items. If any of these items are missing or damaged, contact the supplier. • • COMM+232.
Card Setup Card Setup Address and IRQ selection The COMM+232.PCI is automatically assigned I/O addresses and IRQs by your motherboard BIOS. Only the I/O address may be modified by the user. Adding or removing other hardware may change the assignment of I/O addresses and IRQs. Clock Modes The COMM+232.PCI employs a unique clocking option that allows the end user to select from divide by 4 and divide by 1 clocking modes. These modes are selected at Headers E1 and E2.
E1 E2 DIV1 DIV4 DIV4 DIV1 Card Setup To select the maximum data rate (460.8K bps) place the jumper in the divide by 1 (silk-screen DIV1) position. Figure 2 - Clocking Mode 'Divide By 1’ Baud Rates and Divisors for the ‘DIV1’ mode The following table shows some common data rates and the rates you should choose if using the adapter in the ‘DIV1’ mode. For this Data Rate 1200 bps 2400 bps 4800 bps 9600 bps 19.2K bps 57.6 K bps 115.2 K bps 230.4K bps 460.
Installation Installation Operating System Installation For Windows Users Start by choosing Install Software at the beginning of the CD. Choose Asynchronous COM: Port Software, SeaCOM. Other Operating Systems Refer to the appropriate section of the Serial Utilities Software. System Installation The COMM+232.PCI can be installed in any of the PCI expansion slots and contains several jumper straps for each port that must be set for proper operation. 1. 2. 3. 4. 5. 6. 7. Turn off PC power.
Technical Description Technical Description The Sealevel Systems COMM+232.PCI provides a PCI interface adapter with 2 asynchronous serial ports providing a versatile interface for modems, printers and plotters. The COMM+232.PCI utilizes the 16550 UART. This chip features programmable baud rates, data format, interrupt control and a 16-byte input and output FIFO. A full array of advanced UARTS is also available for this card. Contact Sealevel Systems for more information.
Technical Description The ISP is at Base+7 on each port (Example: Base = 280 Hex, Status Port = 287, 28F… etc.). The COMM+232.PCI will allow any one of the available locations to be read to obtain the value in the status register. Both status ports on the COMM+232.PCI are identical, so any one can be read. Example: This indicates that Channel 2 has an interrupt pending.

Error! Reference source not found. Appendix A - Troubleshooting Serial Utility test software is supplied with the Sealevel Systems adapter and will be used in the troubleshooting procedures. By using this software and following these simple steps, most common problems can be eliminated 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.
Error! Reference source not found. PCI COM: Number Selection in Windows 95/98 When installing a multi-port PCI card in Windows 95 the default starting COM: number assigned to the first port will be COM:5 if no COM:5 exists. If there is a COM: 5, 6, etc., the next available COM: number will be assigned to the first port with all additional ports following in ascending order.
Appendix B - How To Get Assistance Appendix B - How To Get Assistance Please refer to Appendix A – Troubleshooting prior to calling Technical Support. 1. Read this manual thoroughly before attempting to install the adapter in your system. 2. When calling for technical assistance, please have your user manual and current adapter settings. If possible, please have the adapter installed in a computer ready to run diagnostics. 3. Sealevel Systems maintains a Home page on the Internet.
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 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.
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.

Appendix F - Compliance Notices Appendix F - Compliance Notices Federal Communications Commission Statement This equipment has been tested and found to comply with the limits for Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a residential installation.
Appendix F - Compliance Notices EMC Directive Statement Products bearing the CE Label fulfill the requirements of the EMC directive (89/336/EEC) and of the low-voltage directive (73/23/EEC) issued by the European Commission.
