The recieved command means the data of the first analog input is "0769",and it is equal to 1897 in decimal,then substitute into
the fomula: I=(DATA*20)/4095=(1897*20)/4095≈9.26mA.The current in the other channel is 0mA.

Converting reading data "05" to 2 hexadecimal results "00000101", last 4 numbers are active. From left to right, it represents
the 4 digital input channel status DI_04~ DI_01. Here it means DI_03 、 D I_01 have input but others no.
5.4 、 C ommand for digital output (several controls) ：

Converting reading data "03" to 2 hexadecimal results "0000 0011", last 4 numbers are active. From left to right, it represents
the 4 digital output channel status DI_04 ~ DI_01. Here it means DO_02 、 D O_01 have output but others no. When module
receives correct command, it will make corresponding actions and send response back to the master. This is successful
communication.
