Mode Current Consumption

5.5. IO200 Output Voltage

IO200 can supply DC voltage to accessories.

Option_V+ line (Main Connector, pin #14) can drive 100mA @ 2.775VDC. Using this source for external RS232 transceiver

ensures proper communication at correct voltage levels.

5.6. Turning the Unit On

IO200 is powered from a single power supply in the range of 3.2 to 4.2 VDC.

The unit will not power up automatically by connecting the power. To turn the unit ON, apply 4V to ON/OFF pin (Main connector,

pin 5).

To verify that the unit is On or Off, check the OPTION_V+ line (pin #14). If it is high, the unit is on; if it is low, the unit is off.
