CompactPCI® Serial  •  Dual-Port Isolated RS-485 Interface

The CU5-HUM is a dual-port isolated RS-485 Interface for PICMG® CompactPCI® Serial systems. It is an assembly unit, comprised of the CK2-SESSION XMC module carrier card, and the DU1-MUSTANG RS-485 XMC mezzanine module.

Both D-Sub front panel connectors are isolated against the board circuitry and withstand up to 250VAC. The 16Mbps EIA/TIA-485 transceivers can be configured for full- or half-duplex operation, either point-to-point or multipoint applications.
