CUE-BALLAD

CompactPCI® Classic  •  Quad Isolated RS-232 Interface


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.

CUE-BALLAD (D-Sub Front I/O)

CUE-BALLAD • Option D-Sub Front I/O

The CUE-BALLAD is equipped with the Pericom PI7C9X7958 PCI Express® octal UART, which is suitable for asynchronous baud rates up to 15Mbps. Four UART channels are wired to RJ45 front panel jacks across RS-232 transceivers. Each port is comprised of the receive and transmit data signals (RXD, TXD), and in addition two hardware handshake signals (CTS, RTS) which may be used to control the data stream in order to avoid buffer overflow or underrun, as an alternate method to software control by X-ON/X-OFF characters.

Four ADM3252E transceivers are provided to meet the RS-232 physical layer specifications. The RS-232 signals of any particular RJ45 front panel jack are isolated from the board circuitry, and also isolated from each other port. Two pin assignments are available for the RJ45 jacks, a CUE-BALLAD native alignment which is optimized for low-cost Ethernet crossover patch cable usage as RS-232 connection between two CUE-BALLAD equipped systems, and a legacy CU4-SOPRANO layout.


As an alternate to the RJ45 jacks, four 2.54mm pitch pin headers PU1-4 can be optionally populated on-board, for attachment of classic D-Sub 9-pin connectors by means of micro ribbon flat cables, to be combined with a non-standard 8HP width front panel.

The CUE-BALLAD can be configured also for rear I/O usage. Four UART ports are wired as TTL level signals to the optional backplane connector J2, for use with a suitable RIO PHY module, typically configured as either RS-232 or RS-485. Hence, with both front and rear I/O capabilities utilised, the CUE-BALLAD is a true 8-port asynchronous serial interface solution.

As an alternate to J2 RIO, optional 2.0mm pitch shrouded headers PU5-8 can be provided for attachment of CU-series PHY modules.
