This document applies to newer Melco EMT16 and Bravo embroidery machines running Melco OS v11, Bravo OS v11, and AMAYA OS v10.01.001 (specifically). If you encounter detection issues with Melco AMAYA XT or XTS machines running earlier AMAYA OS software, refer to this document instead.
If an EMT16 or Bravo is not being detected by Melco OS or Bravo OS, make sure of the following:
- Look at the LED on the control panel on the right-hand side of the embroidery machine. If it's RED, that typically indicates that the Emergency Stop Button is engaged. Turn the button to the right, in the direction of the arrows, and it will disengage/release and the LED will turn GREEN. The machine should then be detected.
- Make sure that the computer's Ethernet Adapter is listed and selected/highlighted within Melco OS or Bravo OS. Choose: Tools - Options - Ethernet and select your Ethernet Adapter from the list. If there are no network adapters listed in the box, review the options below and then reinstall the software included with your Melco machine.
- Disable any Anti-Virus Network Firewalls. Numerous security programs block unrecognized data transfers through the computer's Ethernet port.
- Verify that IPv6 network protocols are enabled. Without IPv6 functioning, new Melco embroidery machines will not be able to communicate with the computer.
Microsoft Knowledgebase Article 929852 provides specific details on enabling/disabling IPv6 protocols. Microsoft specifically notes that "Internet Protocol version 6 (IPv6) is a mandatory part of Windows Vista and later versions of Windows. We do not recommend that you disable IPv6 or its components. If you do, some Windows components may not function."
Here are the steps to check for, and enable IPv6 if it has been disabled on your Ethernet Adapter:
Open Windows' Network and Sharing Center. Click on "Change Adapter Settings":
Right-click on the Ethernet adapter that your Melco embroidery machine is connected to. Make sure that the IPv6 protocol is checked:
If IPv6 was unchecked, checking that box can resolve the detection issue. A computer restart may be required after checking that box.
If IPv6 is already checked, Right-click on the Ethernet adapter again and choose "Status":
Click on the "Details" button:
Observe the "Link-local IPv6 Address" line below. If there is no information listed on that line, follow the Microsoft Knowledgebase Article 929582 instructions to enable that protocol.
Here is Microsoft's overview of the Internet Protocol version 6 (IPv6) technology.
