2.2.11 Input and output functions (external control interfaces)
(1) GP-IB interface
All items that are operated on the panel can be GP-IB controlled.
Measured results comprising 5-digit exponential measured values, comparison
results and check of measured state are sent in one line of data strings.
Responses in 4-digit fixed decimal points or 5-digit integers are sent to query
commands.
(2) Specification of RS-232 interface function
All items that are operated on the panel can be RS-232C controlled.
Measured results comprising 5-digit exponential measured values, comparison
results and check of measured state are sent in one line of data strings.
Responses in 4-digit fixed decimal points or 5-digit integers are sent to query
commands.
(3) Specification of handler interface function
The interface for measurement by directly operating the meter using the handler
used in measurement.
The communication items and electrical specification are as follows.
• Communication items
Opening and closing of shielding box, key lock of front panel keys, contact
start, measurement start, contact check start, contact check result
measuring voltage on and off, decision results, analog measurement end
measurement computing end, troubles that have occurred.
• Electrical specification
Contact input and output by a photocoupler
Connector product No. is 57LE-40360-7700
4) Specification of interface function for control of dedicated power supply unit
PSU - 8541
Using the dedicated power supply unit PSU - 8541, insulation resistance can be
measured operating the DSM8542. Voltage and current can be set and voltage
ON/OFF can be selected. The control items are as follows.
Voltage setting
Current limiter for measurement and current value setting (Common for all channels)
Current limiter for charging and current value setting (Common for all channels)
Voltage output
ON/OFF
Voltage generator filter ON/OFF
