3.3. Power Supply Control of the Module TC65.

In addition to the regular methods of power supply control of the GSM module TC65

(power-off by the command AT^SMSO, emergency power-off , thermal shutdown etc.), the

Terminal is equipped with some supplementary power supply control functions:

3.3.1. Automatic power-on upon voltage supply.

The module is automatically activated with supply voltage feeding. Exception is

only the case where both SIM mount “trays” are not clicked while the power supply

feeding. In this case the Controller will transmit the initiating command to the

module after clicking of at least one “tray”.

3.3.2. The module starting upon activation of the external DTR signal of the

interface “Serial 1” (ASC0).

Enabling or disabling of this function, as well as the time of retention of the active

DTR status before the start is defined by the Controller setting (I2C command

TC65_DTR_ON see Table 5).

3.3.3. Disabling of the module upon deactivating of the external DTR signal of the

interface “Serial 1” (ASC0).

Enabling or disabling of this function, as well as the time of retention of the passive

DTR status before disconnecting is defined by the Controller setting

(I2Ccommand TC65_DTR_OFF see Table 5).

3.3.4. Disabling of restarting of the module through transmission of I2C

commands. (TC65_off and TC65_reset see Table 3.1 ).
