SUA-RIO

CompactPCI® Serial • Quad Port Isolated RS-485 Interface

Rear I/O Transition Module • Mezzanine Expansion Module

Proven and reliable, RS-232 stays a popular point-to-point low power communication interface.

The SUA-RIO is basically a rear I/O transition module for CompactPCI© Serial systems. The board is equipped with four isolated rear panel RS-232 ports. Isolation barrier transceivers are provided for optimum noise and EMC immunity up to 920kbps data rate, as required for industrial use and operation in harsh environments.

In addition, the SUA-RIO can be configured as a mezzanine expansion module, suitable e.g. for the CompactPCI© Serial cards SU1-TWIST (isolated RS-485), SU2-BALLAD (isolated RS-232), SUB-RIO (isolated RS-485), and the SUA-RIO itself. When used as mezzanine board in addition to a carrier card, the SUA-RIO doubles the number of ports available from four to eight, and allows also mixed configurations RS-232 and RS-485.

When used as a rear I/O transition module, the SUA-RIO is equipped with the CompactPCI© Serial backplane connector rJ4, sourced from either the SU1-TWIST or SU2-BALLAD octal UART cards via P4 RIO.

When used as a mezzanine expansion module, the backplane connector rJ4 is not populated. Instead, TTL-level UART ports are passed via on-board stacking connectors M51 to M84, for either top or bottom mount assemblies, with a common 8HP rear (or front) panel.

The isolated RS-232 ports are wired to Micro-D rear (front) panel connectors. Micro-D to Micro-D cable assemblies are available, as well as Micro-D to D-Sub, and pigtail Micro-D cables in addition. As an alternate, the SUA-RIO can be equipped with classic D-SUB 9-pin connectors, attached by means of flat cable assemblies (on-board headers PU5 to PU8).
