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.
