It is not advertised as universally compatible with every Rnet device, controller, or control system.Please compare your controller and service-port connection with the listing photographs before purchasing. If you are uncertain about compatibility, contact the seller through Messages before ordering.This cable functions as a physical communication interface only. It does not provide proprietary software, programming authorization, passwords, licenses, firmware, or access to secured equipment. Successful communication also depends on the controller, computer, drivers, software, permissions, and correct configuration.IMPORTANT 5-PIN CONNECTION WARNINGThe LGR250 Rnet connection uses one straight row of five pins.Carefully align all five pins with all five connector openings before inserting the plug. Every pin must enter its corresponding opening.Do not:• Install the plug off-center
• Leave any pin outside the connector
• Skip a pin position
• Bend the connector while inserting it
• Force the connectionIf the plug does not enter straight with light pressure, remove it and realign it. Incorrect or forced installation may bend the controller pins or damage the connector. Damage caused by misalignment or forced installation is not considered a cable defect.CONDITION AND TESTINGEach cable is custom-assembled, visually inspected, and communication-tested before shipment.
