WAKE-UP WIRING
RECOMMENDED CIRCUIT IMPLEMENTATION – EXAMPLE OF iUP, iUR AND iUC
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:
• With button connected on jack (optional)
• With Pin 2 of COM0 link & COM2 link
• By pressing the “OK” key on keyboard
The wake-up pin must be high impedance. Do not connect
directly any voltage on this pin even if the devices are
10 V tolerant.
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…).
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.
0 = ON mode
Hz = sleep mode
