Roland ME-US3 Overview
The CABLE-ASSY.ME-US3 is a USB to 25-pin RS-232C serial cable for Roland benchtop engravers and 3D Modela milling machines. Many older Roland machines only have a 25-pin serial port, while modern computers no longer have one. This cable bridges that gap so you can keep using your machine with a current PC. This is a genuine, original Roland part – not a copy or compatible replacement.
If your old serial cable or adapter is lost, unreliable, or not recognized by Windows, jobs may stop half-way, characters may be garbled, or the machine may not respond at all. The ME-US3 provides a stable connection and works with Windows 7, 8.1 and 10 in both 32-bit and 64-bit versions.
