Ethernet Cables: Straight-Through vs Crossover

The information below details the proper types of data cables to use when connecting Melco machines to computers.  If you are encountering problems with machine detection, refer instead to the instructions for solving communications issues with AMAYA OS, or with Melco OS and Bravo OS.


  • If a Melco embroidery machine is connected directly to the Ethernet port (network port) of a computer, a Crossover Ethernet Cable must be used.  (Note that some USB-to-Ethernet adapters don't work with a Crossover Cable, and a Straight-Through Ethernet Cable should be used instead.)


  • If multiple Melco embroidery machines are connected through a hub or ethernet switch; Straight-Through Ethernet Cables must be used from the computer to the ethernet switch, and from the hub/switch to the Melco machines.


This image shows the difference between a Straight-Through Ethernet Cable and a Crossover Ethernet cable.  Compare the wires in the connectors at both ends of the Ethernet Cable:
