1-Wire
The 1-Wire bus is available on the 12 pin connector. All 1-Wire communication goes
through this single pin and all 1-Wire devices connected to this pin retrieves its power
directly from the bus (called parasitic power). By this only two wires are needed – the 1-
wire signal and the ground reference – allowing minimal cable installations. For 1-Wire ID-
Button readers, which include a built-in LED, a dedicated output is available for this
purpose. Please consult the M2M Control IDE online help for further information.

DC-Out
A 3.3V DC output is available on the 12 pin connector. It is possible to control the output in
order to save power. The output is short circuit- (to ground), ESD- and transient protected.
The output is also available on the 6 pin serial port 1 connector. Make sure not exceed the
current specification of the output and be aware of inrush currents of the external
equipment may exceed the specifications. It is recommended to install a fuse to protect the
output.
This output must be enabled from the application. Please consult the M2M Control IDE
online manual for more information.
