The Relio R2 Sync Server combines powerful processing with robust synchronous communications. Choose from powerful Intel i7 or i3 dual core processor models, each offering a wealth of standard I/O. Perfect for radar, satellite, and other military applications, the R2 Sync Server provides 4 synchronous ports using the popular Zilog Z85230 ESCC. Each synchronous channel is individually configurable for RS-232, RS-422, RS-485, RS-530/530A or V.35.

Relio systems are designed using COM Express architecture, require low power consumption, operate fanless over a wide 0-50°C temperature range, and are compliant with MIL-STD-810 shock and vibration specifications. The systems provide a long product life cycle and can be easily customized to match specific customer I/O requirements.

Data rates up to 128K bps are supported on each synchronous serial port. A digital phase lock loop (DPLL) circuit is included for reliable communication when using NRZI or FM encoding. Sealevel's SeaMAC synchronous serial driver provides HDLC/SDLC protocols as well as certain configurations of monosync, bi-sync and raw modes for critical communication development and support. Software utilities are provided to speed application development and to assist in field installation.

The R2 Sync Server runs from ultra-reliable mSATA solid-state disk (SSD) that can be preloaded with Microsoft Windows or Linux operating systems. Included brackets allow mounting to panels, under counters and onto other surfaces. The system is available immediately from stock with pricing from $3695.
