Page 9: Hardware Commands
GC864-QUAD-C2/PY-C2 Hardware User Guide 1vv0300744 Rev.1 - 24/10/06 4 Hardware Commands 4.1 Turning ON the GC864-C2 To turn on the GC864-C2 the ON# line must be tied low for at least 1 second and then released. The maximum current that can be drained from the ON# line is 0,1 mA. - Page 10 GC864-QUAD-C2/PY-C2 Hardware User Guide 1vv0300744 Rev.1 - 24/10/06 For example: 1- Let's assume you need to drive the ON# line with a totem pole output of a +3/5 V microcontroller (uP_OUT1): 2- Let's assume you need to drive directly the ON# line inserting the forecast ON/OFF button PL101: Reproduction forbidden without Telit Communications S.p.A.

Page 11: Turning Off The Gc864-C2
1vv0300744 Rev.1 - 24/10/06 4.2 Turning OFF the GC864-C2 The turning off of the device can be done in three ways: • by software command (refer to 1vv0300745 Rev1 GC864-QUAD-C2 / PY-C2 Software User Guide) • by hardware shutdown • by Hardware Unconditional Restart When the device is shut down by software command or by hardware shutdown, it issues to the network a detach request that informs the network that the device will not be reachable any more. - Page 12 GC864-QUAD-C2/PY-C2 Hardware User Guide 1vv0300744 Rev.1 - 24/10/06 NOTE: don't use any pull up resistor on the RESET# line nor any totem pole digital output. Using pull up resistor may bring to latch up problems on the GC864-C2 power regulator and improper functioning of the module. The RESET# line must be connected only in open collector configuration.
