MightyZAP USB to Half Duplex TTL/RS-485 Converter

The MightyZap IR-USB03 is a USB interface board that serves as a USB-to-RS-485 and half-duplex TTL converter. It enables the connection between a PC and MightyZap linear actuators. Using this interface, actuators can be configured, monitored, and tested with the Total Manager software.

The board replaces the older IR-USB02 model and offers several improvements, including a USB-C connector, an integrated termination resistor, and an enhanced electrical protection circuit.

The PC software supports the following functions, among others:

• Setting of operating and system parameters
• Configuration of memory and device parameters
• Execution of motion and functional tests
• Real-time monitoring of key operating data
• Display of error messages
• System initialization and firmware updates
