DC2364A is a LTC2873 single-bus RS485/RS232 multiprotocol transceiver with switchable termination demonstration board. Demonstration circuit 2364A showcases the LTC®2873 RS232/RS485 multiprotocol transceiver with integrated termination. The DC2364A operates as a stand-alone evaluation platform or can be used as a shield with a Linduino® or Arduino microcontroller board for quick and versatile evaluation of the LTC2873. Control signals on the LTC2873 are accessible via test points for external monitoring or control or they can be set by jumpers or by the Linduino GPIO. Bus lines are routed to test points as well as a terminal block for convenient connections to a transmission line. The DC2364A operates from external supplies or directly from the Linduino’s regulated output supplies, configured to 3.3V or 5V with a jumper setting.
