pre-assembled hybrid DC + Ethernet cable manufactured by Martin Professional (Harman). It combines both power (DC) and data (Ethernet) transmission into a single, rugged cable assembly. This cable uses Martin’s DCE-to-DCE hybrid connector format, designed specifically to support power and data signals simultaneously for lighting fixtures and related devices that use the Martin DCE hybrid connection standard. It simplifies installation and reduces cable complexity in professional lighting systems, especially for installations where both power and data are needed over the same run
