3.2.3 Power Supply
Power supply: 12..24 V DC (5% ripple)
Power consumption standby (logged in): . max. approx. 500 mW
Power consumption data connection (connect): max. approx. 2 W
Power consumption power down: max. approx. 200 mW
Power input sleep: max. approx. 300 mW

24 V DC 20 mA 80 mA 8 mA 13 mA
This values have been established for a signal field strength of 20 (AT+CSQ). The current
consumption and therefore the power consumption may increase for poor network
conditions.
These are average values for estimating the current consumption. The used power
supply unit should be able to supply up to 10 W at short notice (pulse duration 577 µs for
period 4.67 ms) to ensure proper operation.
3.2.4 Reset Terminal
Terminal open/unwired: Normal state
Terminal connected to GND (terminal 2): Reset
Reset duration: minimum 300 ms
When the GND potential is removed once more, the device is in initial state.
ATTENTION! All settings that have not been stored will be lost during a reset.
The reset terminal is also used to bring the INSYS GSM small from the power down state
into normal state.
The reset terminal is to be considered as replacement for the combination of the pins
PD_IN and IGT for the Siemens Cellular Engines TC35i or TC35i terminal, respectively.
