DFRobot FIT0772 Industrial Grade RS485 Repeater

Hi Team,

I unable to read data when we connected this repeater between master and slave device.

Master side's A & B cable connect to the input of A& B of repeater and Output of Repeater connect to slave's A & B.

When we check at master side then no any data will appear at master side.

Power given = 24V only.

Please help here.

Thank you
