Introduction Introduction Overview The COMM+8.LPCI provides eight RS-232 ports from a single PCI slot. The board meets the requirements for the MD1 "Low Profile" specification as defined by PCISIG in PCI 2.2 "Low Profile Addendum." The COMM+8.LPCI also features Universal Bus (3.3 and 5.0V) operation. The COMM+8.LPCI ships with a Low Profile PCI bracket that will only work in a Low Profile PCI slot. If you need a standard size PCI bracket, please order Item# 7803S. What is Included The COMM+8.
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-nPlay’ 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.
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. Start Windows. 2.

Appendix A - Troubleshooting Appendix A - Troubleshooting 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.
Appendix B - How To Get Assistance Appendix B - How To Get Assistance 1. Begin by reading through the Troubleshooting Guide in Appendix A. If assistance is still needed please see below. 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 provides an FAQ section on its web site. Please refer to this for many commonly asked questions.
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.
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 E - Silk-Screen 2.536" 4.721" Appendix E - Silk-Screen Sealevel Systems COMM+8.
Appendix F - Compliance Notices Appendix F - Compliance Notices Federal Communications Commission Statement FCC - This equipment has been tested and found to comply with the limits for Class A 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 commercial environment.
