A small but dedicated community has reverse-engineered the protocol. Using a Lattice ICE40 FPGA and an Arduino Due, they created a Protocol Translator Box that sits between a standard Modbus RTU driver and the 9780.z5’s physical interface. This allows you to replace the original host PC with a modern Raspberry Pi running LinuxCNC.

: Beyond just reading codes, it allows for deep clearing of stored historical faults that standard scanners might miss. Installation & Compatibility Supported Systems

The "9780.Z5" refers to the specific part number for the Actia interface. In the aftermarket, there are two primary versions: Full Chip Version:
