4. Communication Protocol 

1.

  All communications between the CONTROLLER and the DEVICE will be under the direct 

supervision of the CONTROLLER. 

When the DEVICE (HDR-40/50) receives the COMMAND from CONTROLLER, the following 
COMMAND is returned. 

 

ACK:   

 

In case that the DEVICE receives a COMMAND not requiring data 

 

DATA: 

In case that the DEVICE receives a COMMAND requiring data 

 

NAK+ERROR DATA:  In case that a communication error is detected or an undefined  
  

 

COMMAND is received 

2.

  The CONTROLLER must not transmit additional COMMAND blocks to a DEVICE (HDR-40/50) prior 

to response to a previous COMMAND block. 

3.

  The CONTROLLER must transmit of bytes in a COMMAND block for with intervals less than 10 

milliseconds. If a DEVICE (HDR-40/50) detects an interruption of a byte in a COMMAND block that 
exceeds 10 milliseconds, it executes a TIME-OUT error sequence, voids the receiving COMMAND 
block, and transmit a NAK (TIME OUT). 

4.

  When a DEVICE (HDR-40/50) receives a COMMAND block from the CONTROLLER, the DEVICE 

must transmit a response within 9 milliseconds. Therefore if the CONTROLLER cannot receive the 
appropriate response from the DEVICE within 10 milliseconds after transmitting the COMMAND 
block the CONTROLLER detects a communication error, and must execute an appropriate process. 

5.

  When a DEVICE (HDR-40/50) detects a communication error, it must immediately transmit a NAK to 

the CONTROLLER. (The content of an error is shown on the COMMAND tables.)  When the 
CONTROLLER receives a NAK, if must immediately stop transmission of the block. The DEVICE 
must not accept a subsequent command within 10 milliseconds after that (except NAK-UNDEFINED 
command) and must execute a necessary process.
