SU4-SOPRANO

CompactPCI® Serial • 8-Port RS-232 & RS-485 Interface

The SU4-SOPRANO is a peripheral slot card for CompactPCI® Serial systems, equipped with a PCI Express® eight channel UART (Universal Asynchronous Receiver Transmitter). All ports are available through Micro-D front panel connectors, and can be user configured individually for either RS-232 or RS-485 by means of DIP-switches. The on-board transceivers allow for maximum bit rates up to 15Mbps when operated in RS-485 mode and up to 1Mbps in RS-232 mode.

Full- and half-duplex is supported for RS-485, with up to 256 nodes on a bus. The line termination can be switched on/off individually.

As an alternate, any particular port (TTL level) can be redirected to the optional backplane connectors P3 and P4, for rear I/O usage together with a suitable rear I/O module.

The SU4-SOPRANO fits into any CompactPCI® Serial peripheral slot that is PCIe enabled.
