Proven and reliable, RS-232 stays a popular point-to-point interface for industrial communication (IOT, Edge Computing). EKF presents the SU2-BALLAD, 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 921.6kbps 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. Up to four RS-232 ports are available via Micro-D or D-SUB front panel connectors. Another four UART channels are wired to the backplane, for rear I/O usage by means of a suitable RIO transition module, either RS-232 or RS-485, with galvanic isolation. As an alternate, mezzanine modules are available for a common 8-port 8HP front panel assembly.
