Before switching this device on again after switching it off, wait at least six seconds. ② AC IN (power inlet) jacks [A]/[B] Connect the included power cords here. Connect the power cord to this device, and then plug it into an AC outlet. Press the power plug latch when disconnecting the power cord. Caution • Be sure to switch off this device before connecting or disconnecting a power cord. ③ Exhaust vent The DME7 is equipped with a cooling fan. Since air is exhausted through here, be sure not to obstruct the exhaust vent. ④ [GPI] ports These are Euroblock connectors for GPI (General Purpose Interface), which input and output control signals. With GPI inputs and outputs, the DME7 can be remotely controlled from custom-made controllers and external devices. The DME7 has 15 analog/digital input terminals, 1 digital input terminal, and 8 output terminals. At [IN] terminals 1 to 15, voltages between 0 and 5 V are detected. Only at [IN] terminal 16, +24 V input is supported, and voltages between 2.5 V and 24 V are identified as high and voltages below 2.5 V as low. [OUT] terminals 1 to 8 are open collector outputs, which switch between open and ground. The output voltage of the +5 V DC terminal is 5 V. Use the included Euroblock plug for making connections (refer to "Connecting a Euroblock plug"). For detailed connection methods and usage examples, refer to "Connecting to the [GPI] ports".
