The equipment response
The equipment, after detected the frame (detection of the blank state more than 24 bit time), runs that frame as the command
message. In the case the frame message is for the own station, the equipment send the response message back; it takes about
1 to 30 ms for this operation. (How long it takes is depends on the contents of the command message.) Therefore, the master,
after sending the command message, should follow the rules shown below
After sending the command message, the master will be in the receiving standby mode within 24 bit time.
