Located at the bottom of the annunciator LED panel is the system
master reset button. Depressing this button will cause a warm reboot
that will restart Windows CE ® and reset the ILR card without
interrupting the power supply.
9 External Power Supply Requirements
Operation of the i-PORT requires an AC or DC power supply.
IDENTEC strongly recommends the use of a linear (transformer) power
supply with or without built-in rectifier. Suitable industrial transformers
are widely available, or can be ordered from IDENTEC.
The use of a switching power supply is not recommended because it
may not be able to provide a sufficient initial inrush current for power
up. The i-PORT consumes about 6 watts under normal use,
consumption increases by 5 watts for the optional LCD heater and by
another 3 to 5 watts when charging the backup battery.
9.1.1 The Power Supply Basic Requirements
For a DC power supply the output voltage must be between 8V and
30V DC. The recommended power range is 12V to 24V DC. Output
power rating should be no less than 12W DC.
