B626 2 CRC c eck code CRC c eck code for all data
T e recieved command means t e data of t e first analog input is “0769”,and it is equal to 1897 in decimal,t en substitute into
t e fomula: I=(DATA*20)/4095=(1897*20)/4095≈9.26mA.T e current in t e ot er c annel is 0mA.

618B 2 CRC c eck code CRC c eck code for all data
Converting reading data “05” to 2 exadecimal results “00000101”, last 4 numbers are active. From left to rig t, it represents
t e 4 digital input c annel status DI_04~ DI_01. Here it means DI_03
、
DI_01 ave input but ot ers no.

7E97 2 CRC c eck code CRC c eck code for all data
Receive: 01 0F 00 00 00 04 54 08
（
example/ exadecimal
）
Converting reading data “03” to 2 exadecimal results “0000 0011”, last 4 numbers are active. From left to rig t, it represents
t e 4 digital output c annel status DI_04 ~ DI_01. Here it means DO_02
、
DO_01 ave output but ot ers no. W en module
receives correct command, it will make corresponding actions and send response back to t e master. T is is successful
communication.
