SU1-TWIST, Quad RS-485 CompactPCI Serial Card

Hamm, Germany, 10 September 2018

Proven and reliable, RS-485 (EIA/TIA-485) stays a popular fieldbus communication interface, due to simple installation via low cost twisted pair copper cables, up to 1200m length.
EKF introduces the SU1-TWIST, a peripheral slot card for CompactPCI Serial systems, based on PCI Express. The board is equipped with four isolated front panel RS-485 ports. High speed RS-485 balanced line transceivers with internal 5kV isolation barrier provide for optimum noise and EMC immunity.
The SU1-TWIST is equipped with an octal PCI Express to UART bridge. The 950-style UARTs are
compatible with many asynchronous serial applications and protocols. Four isolated
EIA/TIA-485 transceivers are wired to Micro-D front panel connectors, individually configurable for fullor half-duplex operation, either point-to-point or multipoint (PartyLine) applications.
Another four UART channels are available via the CompactPCI Serial backplane connector P4 for versatile rear I/O usage.
