Proven and reliable, RS-232 stays a popular point-to-point low power communication interface.
The CUE-BALLAD is a peripheral slot card for CompactPCI® systems, equipped with four front panel RS-232 ports, available through RJ45 jacks. 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 CUE-BALLAD is based on an octal PCI Express® to UART bridge. The 950-style UARTs are compatible with many asynchronous serial applications and protocols. While four ports are available via RJ45 front panel jacks across isolated transceivers conforming to TIA/EIA-232-E and ITU-T V.28 specifications, another four UART channels are wired to the CompactPCI® backplane connector J2, as TTL level signals for rear I/O usage up to 15Mbps data rate per port.
