Wake-Up Mechanism - Ingenico iSelf Series Integration Manual

2.1.3 WAKE-UP MECHANISM

The iUP250LE and the terminal is designed to save power
thanks to a "stand-by and sleep mode".
If the stand-by mode is used, use the wake-up mechanism:
• W ith button connected on jack (optional)
• W ith Pin 2 of COM0 link & COM2 link
• B y pressing the "OK" key on keyboard
WAKE-UP WIRING
RECOMMENDED CIRCUIT IMPLEMENTATION – EXAMPLE OF iUP, iUR AND iUC
0 = ON mode
Hz = sleep mode
High level for wake-up
of external product
The wake-up pin must be high impedance. Do not connect
directly any voltage on this pin even if the devices are
10 V t olerant.
The wake-up pin is driven to "0" by the one asking the wake-up.
It could be driven by any iSelf Series module or any devices
designed to be compliant (Host device...).
Connector
COM0 or COM2
The voltage on this pin must not exceed 10 V in any case.
As the pin is high impedance in Stand-by mode, any leakage
current can wake-up the configuration.
