Introduction and Card Setup Introduction Overview The Sealevel COMM+850.LPCI is a single channel PCI Bus serial I/O adapter. It provides one RS-232 serial port supporting data rates up to 460.8K bps. The board meets the requirements for the MD1 "Low Profile" specification as defined by PCISIG in PCI 2.2 "Low Profile Addendum." The COMM+850.LPCI also features Universal Bus (3.3 and 5.0V) operation. The COMM+850.LPCI ships with a Low Profile PCI bracket that will only work in a Low Profile PCI slot.
Introduction and Card Setup Card Setup Address and IRQ selection The COMM+850.LPCI is automatically assigned resources 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+850.LPCI 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 Header J1.

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.
Appendix B - How To Get Assistance Appendix B - How To Get Assistance Please refer to Troubleshooting Guide prior to calling Technical Support. 1. Begin by reading through the Trouble Shooting 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.
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 E - Silk-Screen Appendix E - Silk-Screen 2.536" 4.721" Sealevel Systems COMM+850.
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.
