If an error repeats a number of times (three times or more for this Instrument), either the sending device or the receiving device sends an RJC to terminate the session. A session ends after the sending device transfers the volume of data determined by the number of parameter sets being transferred, and sends EOD and EOS in response to an ACK from the sending device. Data Receiver Data Sender Operation HBR > Send Request (Optional) < HBS Data Send ACK > Acknowledge < HBS Data Send ACK > Acknowledge : : ACK > Acknowledge < EOD End of Data : Other subsessions : < EOS End of Session 34 The packed with the same packet number is resent when a checksum mismatch or incompatible data format error is detected. Data Receiver Data Sender HBR > < HBS ACK > < HBS ERR > < HBS ERR > < HBS ACK > : : ACK > < EOD : Other subsessions : < EOS Session terminates if ERR is detected a number of times.

Data Receiver Data Sender Operation HBR > Send Request (Optional) < HBS Data Send : (Fixed amount of time elapses) RJC < Timeout error The session can be canceled for any reason by sending an RJC. RJC can be sent by the sending device or the receiving device. The bulk dump session is terminated immediately upon receipt of an RJC. Data Receiver Data Sender Operation HBR > Send Request (Optional) < HBS Data Send ACK > Acknowledge < HBS Data Send : : (Terminate operation) RJC > Data Receive Canceled Data Receiver Data Sender Operation HBR > Send Request (Optional) ACK > Acknowledge < HBS Data Send ACK > Acknowledge < HBS Data Send : : (Terminate operation) < RJC Data Send Canceled BSY is returned to the external device when OBS, OBR, HBS, or HBR is sent while the Instrument mode is not suitable to perform bulk dump, etc. After BSY is received, the external device should wait until the Instrument enters a mode in which the session is enabled.

The bit field position is shown as a decimal format number. • Size field Shows the parameter bit width as a decimal format value. • Array field Shows the parameter array size as a hexadecimal value. • Min-Def-Max field Shows the minimum value, default value, and maximum value for parameter acquisition as a hexadecimal value. • Description field Explains the meaning of parameter values. Unless otherwise specified, setting values are all indicated in decimal format. 23 System Parameters These parameters make it possible for an external device to check the status of the Instrument and for an external device to command some operation of the Instrument. 23.1 System Information Parameter This parameter is a container for system information.
