ENQ: Request for sending
When request for sending is sent to the amplifier, response data changes depending on the status of amplifier.
Response data is returned in the priority order below:
・
Initial request response is answered to the initial data request for sending after the amplifier is powered on.
・
When the amplifier ID is 80h (128), request for sending to the amplifier is ignored.
1. When the amplifier is powered on
①
Host
→
Amplifier (Request for sending)
Amplifier ID Host ID
②
Amplifier
→
Host (Request of data)
Host ID Amplifier ID Command Data number Reading data
③
Host
→
Amplifier (Response of result)
Amplifier ID Host ID
④
Amplifier
→
Host (Communication completion response)
Host ID Amplifier ID
・
When initial response is confirmed, write parameters as necessary.
2. When receiving data reading / parameter reading
See “$R: Data reading/Parameter reading command” on page before.
3. When the status of amplifier changes
①
Host
→
Amplifier (Request for sending)
Amplifier ID Host ID
②
Amplifier
→
Host (Request of data)
Host ID Amplifier ID Command Data number Reading data
③
Host
→
Amplifier (Response of result)
Amplifier ID Host ID
④
Amplifier
→
Host (Communication completion response)
Host ID Amplifier ID
・
The amplifier saves the status when executing request for sending, and emits the above response when the
status in receiving the next request for sending has changed. Read data is the same as in reading data number 8103h.
・
When the amplifier is powered on, in the case where request for sending is sent continuously, data update
request response is answered after initial request response is made.
4. Cases other than the above
①
Host
→
Amplifier (Request for sending)
Amplifier ID Host ID
②
Amplifier
→
Host (Communication completion response)
Host ID Amplifier ID
・
The amplifier makes communication completion response because data is not requested from the host,
and the status of amplifier has not changed.
1
When amplifier is powered on
Initial request response is answered.
2
When receiving data reading / parameter reading
Refer to data reading command processing.
3
When the status of amplifier changes
Data update request is answered.
4
Other cases than the above
Communication completion response is answered.
