Send Response
<Explanation>
The response to a command is transmitted upon completion of the operation. If a command is sent before receiving the
response to the previous command, the operation cannot be guaranteed.
Host
MX61/61L
2) In case the response for a command is not returned (Unsuccessful communication)
All of the commands sent from the host are ignored in the following cases.
Case 1: During initialization of the MX61/61L
Power ON
CTS: OFF
Start of initialization
Send Command
Command
Received command is ignored.
End of initialization (Command receive ready)
CTS: ON
CTS is fixed at ON.
Host
MX61/61L
<Explanation>
The microscope cannot receive any command in the period after power ON until the completion of initialization.
When the MX61/61L is turned ON, CTS (Clear To Send, RS-232C pin 8) is set to OFF, and all commands received from the
host while CTS is OFF are ignored. When initialization completes, CTS goes ON and the MX61/61L is ready for receiving
commands from the host.
Once CTS is turned ON, it does not go OFF until the MX61/61L is turned OFF. The host can identify the completion of
initialization (command receive ready status) by monitoring CTS.
Case 2: While the microscope is in local mode
Local
Send Request Command
Command
<Explanation>
When the MX61/61L is in local mode, it cannot receive any request command except for 1LOG IN.
}The microscope can receive query commands even when it is in local mode.
Host
MX61/61L
Case 3: When the microscope receives a character string other than MX61/61L commands
Send Command
Command
<Explanation>
When the string received by the MX61/61L is not a MX61/61L command (described later), the MX61/61L does not send
a response for it.
Host
