Communication method for command
Host
8527
Command is sent from the host.
When the 8527 received an effective command, it makes the corresponding transaction.
After completion of transaction, a response is transmitted to the host.
The host transmits the next command after confirming the response.
Example of sequence (
*
means the normal data of characters.)

(Command)
8527
side
(Response)
Test
condition
[RESPONSE=ON]
Transmits the response when the
command is effective.
READY
Transmits
[ERROR=0]
OK
[REMOTE=ON]
START command by RS-232C is possible.
Transmits
[ERROR=0]
OK
[SET:MODE=*,
WMARK=*, ・・・・
・・・・・, ILOW=*]
Setting in the lump of test mode and
parameter.
Transmits
[ERROR=0]
OK
[START]
Starts the test.
Transmits
[ERROR=0]
OK
[STATUS?]
Reads out the status data.
Transmits the status data
[STATUS=****].
Note
: The command which can
be used during the test is
RESET or STATUS only.
In test
DATA?
Read-out in the lump of test result.
JUDGE=*, WJUDGE=*, VOLT=*,
CURRENT=*
,
・・・
Transmission in the lump
of test result.

Configuration of command
Command + Parameter + Delimiter
Example
WMARK= 5.00kV
1. Command
The command to control 8527.
It does not a matter whether the command is in capital or small letter.
2. Delimiter
It means the division of transmission data.
3. JIS 8 bit code is used for the command, parameter and delimiter.
4. Command and parameter is divided by “=”.
5. In case that there is no parameter, transmit the delimiter following the command.
Example:
RESET
6. 8527 responses even if a unit is not included in the parameter.
Caution at the transmission of command
Transmit the set command (
○○○○
=) when the 8527 is in READY status.
When the set command is transmitted from the host during the test, 8527 transmits an error
to the host.
