Welcome to Sealevel Systems' monthly newsletter. The goal is to help our valued customers easily receive timely updates on the latest Sealevel developments. We appreciate your business and continue striving to be the best communications and I/O solutions provider in the market.

In This Issue:

Adding to our support for mobile applications, Sealevel has introduced five new serial products offering a convenient way to add RS-232, RS-422, or RS-485 communications to PDAs, laptops, and other portable devices not normally equipped with serial ports. Target applications include medical, point-of-sale (POS), data acquisition, and control.

We are also proud to introduce a new book co-written by well-known technical author Jon Titus and Sealevel President and CEO, Tom O'Hanlan. The Digital I/O Handbook is intended as a training guide and pocket reference for students, plant personnel, and control integrators. This book is offered free with the purchase of qualifying Sealevel digital I/O products.
