Basic Operation
The rear panel of this series of instrument provides an optional interface card in-
tegrating the RS-232 and analog quantity function. The interface card provides
the following capability:
• Remote control of setting values in different modes.
• Remove switching of CC/CV/CR/CW modes.
• Remote monitoring of input voltage/current measurement.
• RS-232 communication interface, please refer to2.5.5 RS–232 Interface
(Optional) for detailed description about the interface.
• Before connecting the hardware device that controls the analog inter-
face, make sure that the hardware device does not output a voltage high-
er than 20% of the specified value to the pin, otherwise the instrument
will be damaged. For example, when setting the voltage or current, the
input voltage can’t exceed 12V, otherwise the instrument will be
damaged.
• In analog quantity remote control mode, the analog quantity input pins
should be used in combination, and cannot be partially connected and
partially left floating.
• Safe electrical isolation is set between this analog interface and input
electrode. Do not connect any ground wire of the analog interface to the
positive and negative terminals of the input interface.
Analog Card Interface Introduction
The analog function interface is located on the optional IT-E167. The pins de-
scription is as below.
