Introduction Introduction Overview The Sealevel Systems VERSA COMM+4.LPCI provides the PC with four RS-232 asynchronous ports. The VERSA COMM+4.LPCI allows for connection to any device utilizing the RS-232 electrical interface, such as modems, data-entry terminals, and plotters. The VERSA COMM+4.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# 7406S. What is Included The VERSA COMM+4.
Card Setup Card Setup Clock Modes The VERSA COMM+4.LPCI employs a unique clocking option that allows the end user to select from divide by 4, and divide by 1 clocking modes. This mode is selected at E1. 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). D1 D4 Figure 1 - Clocking Mode ‘Divide By 4’ To select the maximum data rate (460.
Card Setup Baud Rates and Divisors for the ‘Div1’ mode The following table shows some common data rates and the rates you should choose to match them 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 460.8K bps Choose this Data Rate 300 bps 600 bps 1200 bps 2400 bps 4800 bps 9600 bps 19.2K bps 57.6 K bps 115.
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 3.3 or 5V 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.
Technical Description Technical Description The VERSA COMM+4.LPCI utilizes the 16C854 UART. This chip features programmable baud rate, data format, interrupt control and a 128-byte input and output FIFO, and is functionally 4 16C850 UARTs.

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-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 Appendix E - Silk-Screen 2.536" 4.721" Sealevel Systems VERSA COMM+4.
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.
