FAQ

This cable follows the standard Schneider Electric Modbus pinout for RJ45 connectors. It is a straight-through cable designed specifically for their equipment. Always refer to the manuals of the connected devices to confirm compatibility.

While they use the same RJ45 connector, it is not recommended. Standard ethernet cables may have different pinouts (e.g., crossover) or lack the required shielding and impedance characteristics for robust RS485/Modbus communication, which can lead to data errors and connection issues.

No, this cable is specifically designed for Modbus serial link (RS485). Modbus TCP/IP runs over an Ethernet network and requires standard Category 5e or better Ethernet cables.
