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.
The CUD-TWIST is a peripheral slot card for CompactPCI® systems, 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 CUD-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 RJ45 front panel jacks, individually configurable for full-duplex operation (4+1 wire cable) or half-duplex (2+1 wire cable), either point-to-point or multipoint applications. Another four UART channels are wired to the CompactPCI® backplane connector J2 for rear I/O usage.

The CB3-TONE is a CompacPCI® peripheral card, equipped with a PCI Express® to USB 3.0 quad-port controller. Four USB 3.0 receptacles are available via the front panel for attachment of external USB 3.0 and USB 2.0 compliant devices. Electronic power switches are provided, for up to +5V/1.5A load at any USB connector. The USB controller supports all data transfer protocols on any connector, SuperSpeed (USB 3.0 xHCI) as well as high-speed, full-speed, and low-speed. The CB3-TONE is provided with a PCI® to PCI Express® bridge, as interface between the USB controller and the CompacPCI® backplane.
The CB3-TONE is equipped with the TI TUSB7340 single chip PCI Express® to USB 3.0 bridge. The xHCI (SuperSpeed) compliant host controller supports up to four downstream ports. Each downstream port may be independently enabled and has individual power control and overcurrent detection.

SuperSpeed USB 3.0 offers ten times the data speed of USB 2.0 (5 Gbit/s compared to 480 Mbit/s). The bandwidth of the xHCI controller is shared over all TUSB7340 downstream ports. Texas Instruments provides xHCI compliant Windows® drivers for download.

The ATC139 is a carrier for dual shelf managers (VadaTech’s VT011). The board allows the use of high-performance shelf managers in any AdvancedTCA system.
