USB to DB25 Serial Cable for a CNC machine

This USB cable allows a computer or Raspberry Pi to connect directly to an industrial CNC controller.  The circuit inside mimics a RS232 serial port, so the computer software can utilize a standard COM port.   Standard off the shelf serial cables will generally not work with industrial CNC machines because there are pins that need to be connected together on the DB25 connector.  Custom cables can be purchased, or you can make your own.  This USB to serial cable makes it easy to add the connections using internal switches that can be configured to your CNC controllers settings, rather than soldering wires together.  Specifications: Length: 1 meter (~3ft, 4 inches) End 1: USB-A male, USB2.0 End 2: DB25 male, RS232 with full HW handshaking (RTS, CTS) Max Speed: > 1M bps (Most CNC Machines are <115200bps) Power Consumption: 5.2mA @ 5.0VDC Indicators:  TX and RX LEDs Drivers: FTDI drivers are usually already part of Linux and Windows If a longer cable is needed, it can be extended u
