CompactPCI® Serial Quad Port Isolated RS-232 Interface

Proven and reliable, RS-232 stays a popular point-to-point low power communication interface.
The SU2-BALLAD is a peripheral slot card for CompactPCI® Serial systems, equipped with four front panel RS-232 ports. Isolation barrier transceivers are provided for optimum noise and EMC immunity up to 460kbps data rate, as required for industrial use and operation in harsh environments. The SU2-BALLAD is based on an octal PCI Express® to UART bridge. The 950-style UARTs are compatible with all typical asynchronous serial applications and protocols. While four RS-232 ports are available via Micro-D front panel connectors across isolated transceivers conforming to TIA/EIA-232-E specifications, another four UART channels are wired to the CompactPCI® backplane connector P4, for rear I/O usage by means of a suitable RIO module.
