Hi Prashant, To configure the AD2428WD1BZ as slave board, Please refer the Jumpers settings section in the EVAL-AD2428WD1BZ Evaluation board manual. The link is below. www.analog.com/.../EVAL-AD2428WD1BZ_Manual.pdf In addition, please note that by default A2B transceivers are slave mode. You need to set the A2B_CONTROL.MSTR bit to change the transceiver to the Master mode. Also please ensure two checkpoints that power (Either bus or local)and Bus link(from the master) to the Slave Board before configuring the slave board. An A2B system is brought up by the A2B host. Once power is properly established, each node in the system must be discovered and configured in order, starting with the master node. Further, All slave nodes are discovered sequentially from slave 0 to the last available slave in the system with the software flow shown in the Simple Discovery Flow figure given in the AD242x TRM. In this figure, the stages show commands as issued over the I2C interface between the host and the master-enabled transceiver. Regards, Dinesh

Yes, We don't need to set the A2B_CONTROL.MSTR bit for the slave nodes(in your case AD2428WD1BZ) when discovering and initializing. But to discover the slave nodes we need the A2B master enabled transceiver.
