The CRC segment is the frame that examines the frame transmission error, consisting of 15-bit 

CRC sequences and 1-bit CRC delimiter (the bit used for separation). 

CRC sequence is the CRC value generated by the polynomial, and the calculation range of CRC 

includes frame start, arbitration segment, control segment and data segment. The receiver calculates 

the CRC with the same algorithm and

 

makes comparisons. If any inconsistencies, it will notify the 

error. 

7.2.2.7 ACK segment 

The ACK segment is used to confirm that the reception is normal, consisting of two bits that 

are an ACK slot (ACK Slot) and an ACK delimiter. 

An ACK is sent in the unit(the sending unit does not send an ACK) which can receive the normal 

message and belongs to one of all receiving units that are neither in the bus shutdown nor in 

hibernation. A normal message means a message that does not contain a stuff error, a formal error 

or a CRC error. 

7.2.2.8 Frame end 

The frame end is a segment representing the end of the frame, consisting of 7 recessive bits. 

7.2.3 Communication application 

In communication, a data frame can be divided into multiple segments with different functions. 

Except for the data segment, the meaning of the other segments has been explained in the previous 

section, so this section will not explain in detail, and only describes the information of data 

segment. 

The data bits of the example given in this section are hexadecimal. Data segment takes the format 

of the command (function code) + data. 

7.2.3.1 Startup command 

01

 

01 

Description: When the AIM-M300 series insulation monitoring device monitors the insulation 

faults in the isolated power system, it will issue a startup command to initiate the AIL150-4/8 

fault locator. After receiving this command, the AIL150-4/8 fault locator begins the insulation 

fault locating. 

 

7.2.3.2 Fault location results return command 

04 01 

Description: After the AIL150-4 insulation fault locating is completed, the locating results 

are sent to the AIM-M300 series medical intelligent insulation monitoring device. 

Other commands will not be repeated here.
