Option 09: Ethernet interface

FunctionControl with external controller (except for power switch)Connector10base-T Disables the power switch on the front panel and automatically restores power after power failure.ON/OFF operation can be performed using the standby Functionswitch on the rear panel.

Option 17: I/Q balanced input ∗

Power switch on the front panel of this unit does not have alatching function. Therefore, if power is interrupted in the ON status, the standby status is kept even after power is restored.
