> 3.5.1 | Switch on TC65 Terminal

> There are several ways to turn on the TC65 Terminal:

> • | Switch on via ON/OFF push button or via ONOFF signal line on IO interface connector: The major approach is to switch on the TC65 Terminal by pressing the ON/OFF key. The ONOFF pin of the IO connector is connected in parallel to the ON/OFF key and makes possible to control the TC65 Terminal from a remote unit.

> • | Switch on via IGT_IN line (power supply connector) or DTR line (serial connector). The rising edge of the IGT_IN line or the DTR line voltage generates an ignition signal (impulse) so that it is possible to switch on the TC65 Terminal from the host or by remote control.

> • | Switch on via recommended power supply unit: By connecting the TC65 Terminal with the recommended power supply unit the TC65 Terminal starts to work. See Chapter 7 for ordering information the power supply unit.

> Switch on condition: When the TC65 Terminal is off the ON/OFF push button or the ON/OFF signal line must be asserted for at least 400 ms and then released.
