Introduction Introduction Overview The Sealevel Systems SeaLINK+232 equips the PC with 1 USB to RS-232 Asynchronous serial port providing a versatile interface for common RS-232 needs (i.e. modem, mouse and plotter). The advantage of this product over more traditional approaches is that it doesn’t require opening the computer case, nor does it require resources such as I/O ports or IRQs. It does require a system that supports USB both in terms of hardware and operating system.
Installation Installation Windows 98/ME/2000/XP Installation 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 of the CD 4. Select ‘Install Software’. 5. Select the part number for your adapter from the listing. 6.
Technical Description Technical Description The SeaLINK+232 utilizes a USB UART. This chip features programmable baud rate, data format, 128 byte Dual Port TX Buffer, and 384 byte Dual Port RX Buffer. The RS-232 transceiver supports data rates up to 460.8K baud. Refer to Appendix C for cable length limitations. Features • Hot-Pluggable device that doesn’t require opening the case • No system resources are required (i.e.
Specifications Specifications Specification Temperature Range Humidity Range Operating 0º to 70º C (32º to 158º F) 10 to 90% R.H. Non-Condensing Storage -50º to 105º C (-58º to 221º F) 10 to 90% R.H. Non-Condensing Manufacturing All Sealevel Systems Printed Circuit boards are built to UL 94V0 rating and are 100% electrically tested. These printed circuit boards are solder mask over bare copper or solder mask over tin nickel.
Appendix A – Troubleshooting Appendix A - Troubleshooting Serial Utility test software is supplied with the Sealevel Systems adapter and will be used in the troubleshooting procedures. Using this software and following these simple steps, most common problems can be eliminated without the need to call Technical Support. 1. If your adapter isn’t working, first check to make sure that USB support is enabled in the System BIOS and it is functioning properly in the operating system.
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 - Compliance Notices Appendix E - 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.
