A leading radio broadcasting company required a reliable, small, cost-effective solution for monitoring and control at radio transmitter sites. In addition to the dense I/O requirements, the customer requested that the design allow for easy upgrade or replacement of the single board computer. Sealevel designed a custom Relio system providing a variety of serial, analog, and digital I/O that can be queried or send alerts via the internet or a standard telephone connection. The system supports Windows XP or Linux and the design includes 64 optically isolated inputs, 64 digital outputs, 24 14-bit analog inputs, voice modem with DTMF, serial, USB, and Ethernet functionality in a 1U rackmount enclosure.
