Check sum

Command 1

Command 1, along with command 2, is a number used to distinguish each command.

In the case of ACK, when the lower order 4 bits is FH (as in 3FH and 7FH), this indicates that the commands and data of the supported equipment have been received. When the lower order 4 bits is BH (as in 3BH and 7BH), this indicates that unsupported commands and data have been received.

Unit ID 1 and Unit ID 2

Unit ID 1 and unit ID 2 are numbers used to identify the equipment that is to be connected.

60H is used for the plasma monitor and 80H is used for external control equipment such as a personal computer.

1)Unit ID 1: Indicates the equipment sending the signal

2)Unit ID 2: Indicates the equipment receiving the signal

Command 2

Command 2, along with command 1, is a number used to distinguish each command.

Check Sum (CKS), Error Processing, and ACK

1)The check sum described below and RS-232C odd parity are used together for a check of the received data. The check sum is the lower order 8 bits of one frame of sent or received data comprising the sum total of Command 1, Unit ID 1 and 2, Command 2, Data Length, and Data.

2)Error Processing

When the communication interval is vacant for more than 4 ms, thereafter a received Command 1 will be recognized. If, at this time, meaningful data cannot be recognized, that data will not be recognized (as valid data).

An ACK will not be returned unless the receive data error, the check sum error, and the receive data are all taken in.

Running Sense

Running Sense

Running Sense

The plasma monitor regularly transmits a Running Sense command at an interval of approximately 1 second. (Running Sense command: 1FH 60H E0H 88H 00H E7H) This command is used to recognize optional equipment. The return of an ACK is not required when external equip- ment such as a personal computer has been connected. Note that destruction of this data is recommended when it is taken in.

When various commands are to be sent from external equip- ment such as a personal computer, the plasma monitor is always receive enabled.

Note that when an ACK has not been returned from the plasma monitor in 1.5 seconds, a resending of the com- mand is recommended.
