Command line interface

The command line interface allows the user to configure a device using a set of simple text commands (ASCII). In order to send commands to the device, the device is connected to a PC via a serial connection (USB-to-serial cable). The commands are entered in a serial terminal program (e.g. putty) running on the PC.

See Command line and downlink command interface and https://www.decentlab.com/support for further information.

Electrical connection

The device can be connected to a PC using a commercially available USB-to-serial cable.

CAUTION: Use USB-to-serial cables with 3 V TTL logic levels (maximum 3.3 V)!

Recommended cable: “TTL-232R-RPi Debug Cable for Raspberry Pi” by FTDI chip. Connect 3 wires to the device connector (female pin header socket, 2.54 mm pitch) as shown in the following illustrations.
