S43-RS485

S43-RS485 is an add-on module for the 4.3" SGD 43-A PanelPilotACE display, providing a three-wire RS485 interface with an optional 120Ω termination resistor. The board mounts directly to the rear of the SGD 43-A for a compact, integrated installation. Connections are made via A (Data+), B (Data–) and GND pins, supporting half-duplex communication. The PanelPilotACE software currently supports ASCII-based serial communication and MODBUS RTU, with additional protocol support under development.
