Power and Signal Connections
The USB-C connector on top of the device provides a serial interface to
CODA KM-Series mass flow meters. Meters can be powered via the USB-C,
DB-15, or M12 connector. The USB-C connector is not available on IP67-
rated devices. By default, CODA instruments have a male DB-15 connector.
