4.1.3 Status Indicator Lights
Four LED status indicators are located directly above the mains circuit breaker. These LED’s
correspond to the following conditions:
REMOTE
The REMOTE LED indicates that the unit is in remote control
mode. If the IEEE-488 interface is used, this indicator will be lit
whenever the REM line (REMOTE ENABLE) line is asserted by
the IEEE controller. If the RS232, USB or LAN interface is used,
the REMOTE state can be enabled by the controller using the
SYST:REM command. Any time the REMOTE LED is lit, the
front panel of the MX Series unit is disabled. There is no
LOCAL button that allows the user to regain control of the front
panel. This prevents accidental change of settings in ATE
applications.
