6. Installation and Maintenance
Installation
Insert the module into the corresponding slot of the VME‑64 chassis and secure it with screws to complete mechanical installation. Connect the 24 V power supply and link the module to the host computer via the XVME bus.
Wiring
Connect sensors or actuators according to the output/input specifications, with attention to polarity and shielding requirements to ensure signal integrity.
Debugging
Use host software to perform channel mapping and calibration for optimal signal accuracy.
Maintenance
Hot-swapping support allows faulty modules to be replaced without system shutdown. Periodically inspect the power supply, heat sink, and connection terminals to maintain the IP65 protection rating and overall system reliability.
