BT348 is a small and cost-effective terminal for the serial remote control of motrona devices and controllers or drives of such manufacturers using the same serial transmission protocol. The device allows the cyclic reading and display of a given parameter as well as the change of the parameter value via the front-panel keys in the simplest way. The communication protocol is often used in drives and other devices in automation. All the details of the protocol are described in detail in our documentation “SERPRO”.
