The Mod. A5818 is a PCI Express Gen 3 x8 card that can plug into x8 or x16 PCI Express slots, which allows the User to control up to 4 CONET2 independent networks (each network can be made of up to 8 CONET 2 slaves).

CONET2 is an optical link-based network with Daisy chain capabilities. Through the CONET2 it is possible to handle the VMEbus through the CAEN VMEbus Optical Link Bridges (such as the V3718, VX3718 or V4718, VX4718) or to control directly CAEN modules with built-in optical link (such as standard CAEN digitizers).

The communication path uses optical fiber cables as physical transmission line (AI2700 – Optical Fiber Series).
