Page 45: Can Bus Communication (Remote 1)
LAMBDA Laboratory Instruments PERISTALTIC PUMPS Manual 12/2025 13 CAN BUS COMMUNICATION (REMOTE 1) The peristaltic pump implements the CAN Specification 2.0B (Controller Area Network) interface. This asynchronous serial data communication protocol provides reliable communication in an electrically noisy environment. For internal purposes, the auxiliary bits in the extended identifier are used for the 1x master/n-slave communication model. - Page 46 LAMBDA Laboratory Instruments PERISTALTIC PUMPS Manual 12/2025 extended data frames. The IDE bit indicates the data frame type. IDE is 1 for the extended data frame. The extended data frame Control field consists of seven bits. The first bit is the RTR. For the extended data frame, RTR is 0. The next two bits, RB1 and RB0, are reserved bits in the dominant state (logic level ‘0’).
