Introduction Introduction Overview The Sealevel Systems ULTRA-COMM+2.LPCI is a two channel Low Profile PCI serial I/O adapter for the PC and compatibles. It provides two field selectable RS-232/422/485 serial ports supporting data rates up to 921.6K bps. Configure both ports as RS-232 for standard serial COM: port requirements. Choose the RS-422 mode for long distance device connections up to 4000ft. where noise immunity and high data integrity are essential.
Installation Card Setup In all cases J1x refers to settings for the first port and J2x refer to settings for the second port. RS-485 Enable Modes RS-485 is ideal for multi-drop or network environments. RS-485 requires a tri-state driver that will allow the electrical presence of the driver to be removed from the line. The driver is in a tri-state or high impedance condition when this occurs. Only one driver may be active at a time and the other driver(s) must be tri-stated.

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.
Installation Line Termination Typically, each end of the RS-485 bus must have line terminating resistors (RS-422 terminates at the receive end only). A 120-ohm resistor is across each RS-422/485 input in addition to a 1K ohm pull-up/pull-down combination that biases the receiver inputs. Headers J1A and J2A allow the user to customize this interface to their specific requirements. Each jumper position corresponds to a specific portion of the interface. If multiple ULTRA COMM+2.

This is selectable via four 24 pin DIP-shunts at E1-E4. Please use the following illustration to aid in the configuration of your electrical interface.
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. Insert the Sealevel Systems CD in to your CD drive. 3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch. Otherwise, point your browser to the ‘Index.htm’ on the root directory of the CD 4. Select ‘Install Software’. 5. Select the Part Number for your adapter from the listing.
Installation Physical Installation The adapter can be installed in any PCI expansion slot and contains several jumper straps for each port that must be set for proper. Do not install the Adapter in the machine until the software has been fully installed. 1. Turn off PC power. Disconnect the power cord. 2. Remove the PC case cover. 3. Locate an available PCI slot and remove the blank metal slot cover. 4. Gently insert the PCI adapter into the slot. Make sure that the adapter is seated properly. 5.
Technical Description Technical Description The Sealevel Systems ULTRA COMM+2.LPCI provides a Low Profile PCI interface adapter with 2 asynchronous serial ports providing a versatile interface, field selectable as RS-232 for modems, printers and plotters, as well as RS-422/485 for industrial automation and control applications. The ULTRA COMM+2.LPCI utilizes the 16850 UART. This chip features programmable baud rates, data format, interrupt control and a 128-byte input and output FIFO. The ULTRA COMM+2.

Appendix A - Troubleshooting Appendix A - Troubleshooting A Serial Utility Diskette is supplied with the Sealevel Systems adapter and will be used in the troubleshooting procedures. By using this diskette 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.
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 ULTRA COMM+2.
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.
