  • Compact aluminum box 41x94x20 mm3 (WxLxH)

  • 80 MB/s transfer rate by the optical link

  • Up to 8 boards in Daisy Chain on the optical link

  • Suitable for Windows 10/11 and Linux (all kernels)

  • CAEN USB drivers required

  • Drivers available for Windows 10 OS or higher

  • Linux driver required only for not sudoers Users

  • USB powered

The CAEN Mod. A4818 is a CAEN USB 3.0 to CONET adapter, USB-powered. CONET is the CAEN proprietary protocol for the optical link, which is able to communicate with Digitzers and VME Controllers with direct connection or in daisy chain up to 8 boards simultaneously. The A4818 is compliant with the USB 3.1 Gen1 speed protocol and can be connected to any USB port of the PC running Windows or Linux.

The optical link maximum transfer rate is 80 MB/s, which is shared within the boards connected in daisy chain. The A4818 is compliant with optical fibers 50/125 µs OM2 and OM3, as well as with older 62.5/125 µs OM1.
