１１．Remote Ｉ/Ｏ
Overview of the test depending on remote I/O
The control of start/stop of the test is possible with sequencer etc. depending on the remote I/O
connector ⑤ of rear panel.
・ Depending on the input on/off of the address number of the test conditions by registering the test
conditions using memory operation “7. Memory Operation”, it is possible to test by memory contents
reading from outside. Test by panel setting mode is also possible.
・ The control by the sequencer etc. Becomes easy because of the output of READY of test conditions,
during test, end of the test and also judgment result with an open collector.
・ Interlock setting for the safety and guarantee and the signal corresponding to each condition of 8505
outputs through open collector.
・ Input and output signals are insulated from internal circuit by photo coupler. As it has a power supply
of DC24V 0.1A, it can be used as a power supply for the external control.
! Caution
It does not start the test from the START signal of remote I/O connector in case there is a setting
to start from START command of RS-232C.USB interface. Change the settings. See below for
the reference.

During operation of interlock function, there is a display of ERR LOCK in test voltage indicator, output
of 8505 is shut off and all the key operations are disabled.
To release the interlock, INTER-LOCK of remote I/O connector and COM is short circuited and STOP
switch is pressed with “L” level.
After ERR LOCK is off and READY lamp turned on, the test is possible.
Note: The supplied remote I/O plug (36P) has short circuited INTER-LOCK and COM.
In case there is no remote I/O plug, release is possible reintroducing the power, with the help of
setting operation of interlock of “10. Other functions”.
As shown in the connection diagram example given below, allow the adequate interlock processing
where safety is considered like linking with an external device etc.

１．Command
Delimiter
Parameter

５．００kV
Command to control 8505
Upper case and lower case does not matter during command.
It means there is a break in transmitted data.
２．Delimiter
３．Command, parameter and delimiter use JIS8 bit code.
４．In case there is no parameter, transmit the delimiter following the command.
[Example] START 
５．Even if the unit of the parameter is not included, 8505 responses.
Caution during command transmission
Transmit setting command（○○○○=）when 8505 is in READY state.
When setting command is transmitted by the host during the test, 8505 transmits to host the “TEST”
for the test period.
Structure of response
In 8505, when command is transmitted to the host, it performs the analysis and processing and returns
the response.
When the received data is incompatible, 8505 returns an error code to the host.
Refer to the tips of the error code and solution for detail.
[When setting and operation command is valid]
○ For valid setting and operation command, ERROR=0 is always returned to the host.
Example
Valid command ：In case of START
Response ：ERROR=0
[When setting and operation command is invalid]
○ For invalid setting and operation command, ERROR=error code is always returned to the host.
Example Invalid command ：STAT･･･when there is a mistake in spelling during test interruption
Response ：ERROR=1
Response time
As the response time of command list of next page is the reference value, it changes depend
ing on the condition of use.

ERROR=2
ERROR=3
TEST
ERROR=6
ERROR=8
ERROR=９
Error contents and countermeasures
Command format cannot be recognized and the characters are also wrong.
Example）STAART、STAT
Correct the character string to START
Parameter is outside the valid range.
Example）ITIMER=9999
Put it in between 0.2～99.9
Trying to set the parameter in the condition where setting is not possible.
Example）When there is Err E-30 or Err E-31 on the front panel, it is a problem of the tester 8505 side and not
of the transmission.
Refer 「１３．Error message」of the Instruction manual of this tester.
During test or judgment output, the operation other than STOP is performed.
During REMOTE=OFF, When START command is received.
Perform after REMOTE=ON setting.
Command transmission is performed during test conditions setting.
Example）Command transmission is not possible during setting by the front panel operation.
Let the setting end and the light on the READY lamp is in turned on condition.
Command is not appropriate.
Example)
・Even when the previous measurement is the test of PROGRAM operation, DATA? command is received.
・When the previous measurement is the test result other than the test of PROGRAM operation, PROGDATA?
command is received.
・Even when it is not yet measured, DATA? Or PROGDATA? command is received.
・Even when FAIL mode is ON, try to cancel NG and PROTECTION with STOP command.
Regarding protection function operation time（During interlock, error display）
PROTECTION state
ERR CHRG
Countermeasures
When the capacity of the test specimen is large, discharge is not possible and there is a case where
high voltage remains. When DATA? is received at this state, IJUDGE=PROTECT is returned to
the host. Besides, if STOP command is received then ERROR=3 is returned to the host.
Countermeasure
Leave it alone for some time and continue the discharge. When the discharge is completed, it is
possible that the STOP command or error display in STOP switch is released.
Even when command is sent in INTERLOCK state, ERROR=3 is returned to the host.
ERR LOCK
Countermeasure
Release the INTER LOCK and make STOP command or press STOP switch.
ERR E-11
ERR E-21
Cancel the momentary movements.
Refer the error contents in 「１３．Error message 」of the instruction manual of this tester.
ERR E-30
It occurs during withstand voltage test, when the internal components are in the overheated state.
When DATA? is received at this state, WJUDGE=PROTECT is returned to the host. Besides, if
STOP command is received then ERROR=3 is returned to the host.
Countermeasure
There is a possibility of internal components getting overheated during the test for a long time. Wait
for a while at the power on state till the heat is dissipated. When the heat dissipation is completed, it
is possible that the STOP command or error display in STOP switch is released.
