> Function | Signal name | IO | Signal form and level | Comment
> Emergency OFF | EMERGOFF | I | R I ≈ 100kOhm VLmax = 0.8V VLmin = -0.3V VHmin = 4.5V VHmax = 30V signal ___________|~~~~~~~~~~~~|__ | > 1s | > 1s | Rise time < 100ms | Emergency-off switches the power supply of the Terminal off. Data stored in the volatile memory will be lost, if used the emergency off. If unused keep pin open.
> Ignition | IGT_IN | I | R I ≈ 100kOhm, CI ≈ 100nF VLmax = 0.8V VLmin = -0.3V VHmin = 8V VHmax = 30V signal ___________|~~~~~~~~~~~~|__ | > 0.5s | > 0.5s | Rise time < 100ms | This signal switches the mobile ON. It is possible to connect IGT_IN directly to POWER. If unused keep pin open.
> | ONOFF | I | R I ≈ 30kΩ, CI ≈ 10nF VILmax = 0.5V at Imax = -150µA VOHmax = 4.2V ON OFF ~~~~|________|~~~~~~~~~~~~~|________|~~~ | > 0.4s | > 2s | > 1s | Rise time < 1ms | This signal switches the mobile ON and OFF. This line must be driven low by an open drain or open collector driver. If unused keep pin open.
> RS232 | DTR | I | V Imin = ±3V signal ~~~|________|~~~~~~~~~~~~~~~ | > 0.5s | > 0.5s | Rise time < 1ms | This signal switches the module ON with the low high transition.
