Interface and Communication Configuration

No external wiring terminals, double-row gold-plated pins directly inserted into the dedicated key slot on the D136 main control side edge, relying on the internal E-BUS bus of the main control to complete authorization identification, power-on automatic hardware serial number verification, key and main control are bound and cannot be mixed used across controllers. Core function

Hardware encryption unlocks all software functions of the MSC main control. Without this key, the main control retains only the basic local E-BUS IO and disables all field buses, multi-axis extensions, and simulation functions.

The hardware SN of the binding controller is bound, and the program runs based on the key. After the key is removed, the engineering program is locked and cannot be run.

Real-time self-checking. When there is poor contact, the bus indicator light on the main control panel gives an error, and the MACS software pops up a window indicating a lack of authorization.

The full-featured MACS programming menu is open, including advanced algorithm libraries, waveform generators, remote configuration, and simulation connection modules. Applicable scenarios

Aircraft multi-channel actuator integrated test bench, turbine EH hydraulic speed control system, vehicle component multi-channel fatigue testing machine, large-scale hydraulic servo simulation platform, multi-axis electro-hydraulic coordinated loading equipment.

Operation and maintenance instructions

Must be unplugged and powered off for insertion and removal. Do not perform hot insertion and removal. To prevent gold-plated pins from breaking and burning out;

Clean the oil stains and dust on the pins every six months to avoid poor contact and loss of authorization;

Keep away from hydraulic oil, corrosive water vapor, and high-power frequency converter power cables;

If the key is lost, only the original factory can customize the same encoded model. It is impossible to crack the software to activate full functionality permissions.
