Trigger And Remote Sensing Connections
A 4-pin connector and a quick-disconnect mating plug are provided on rear panel for
accessing input signals and remote sensing, all leads connected to the connector
should be twisted and shielded to maintain the instrument's specified performance.
Remote Sensing: sense ( + ) and sense ( - ) Used to connect the remote sensing
leads to the power source.
TRIG IN: TRIG (IN) A TTL-compatible input that responds to external edge trigger
signal. A trigger applied to this input can be used to change settings (voltage, current,
resistance, etc.), toggle between settings in transient-toggle mode, or generate a
pulse in transient-pulse mode.
TRIG GND: TRIG ( ) Provides the common connection for the trigger signals.
Computer Connections
The electronic load can be controlled through a PC serial port.
RS-232 Interface
The electronic loads have an serial port programming interface; all applicable
commands are available through serial port programming. It available to connect the
electronic load to any computer or terminal with the IT-E131 isolated communication
cable.
