NTP250 Back

USB admin console

The Micro-B USB port on the back panel labled "CON" provides an out-of-band admin console for configuring the device or troubleshooting connectivity issues.

Using the console

The NTP200/NTP250 uses a WCH CH340 UART to USB chip. A serial console is presented over this USB port so you can use any terminal program and connect using 115200 baud N81 with no flow control. Press <ENTER> on the USB admin console for help.

Linux

Linux uses the ch341-uart kernel module to interface with the CH340, this driver is included in modern Linux systems.

Use a program such as minicom to connect:

$ minicom -D /dev/ttyUSB0 -b 115200

Windows

Windows does not generally include a driver for the CH340 so you will likely need to install this yourself.

Download the CH340 driver for Windows from WCH and install it.

Once installed use a program such as PuTTY as shown:
