CU3-TRIO

CompactPCI® Classic  •  Triple Isolated RS-485 Interface


The CU3-TRIO is a peripheral slot card for CompactPCI® systems, equipped with a PCI Express® to UART bridge. Three high speed RS-485 balanced line transceivers with internal 5kV isolation barrier provide for optimum noise and EMC immunity. The front bezel D-Sub connectors withstand up to 250VAC measured against shield.


The 950-style UARTs (aka COM ports) are compatible with any asynchronous serial application. Device drivers are available for Windows® and Linux. The 16Mbps EIA/TIA-485 transceivers can be configured for full-duplex operation (4+1 wire cable) or half-duplex (2+1 wire cable), either point-to-point or multipoint applications.
