2.14.2 Functions of the RJ11 Interface
The interface at the RJ11 6-pin connector of the GT863-PY Terminal has the following functions
and physical connections.
• Connection to General Purpose Inputs/Outputs 4, 5, 6, 7, which can be used to

relays. With a user defined PYTHON script element, it is possible within certain limits to
configure these GPIOs as I
2
C or SPI bus. See Chapter on PYTHON of this Product
Description.
• The GPIO6 can be set by AT commands as output for the ALARM (wake-up) signal,
generated by the Real Time Clock RTC.
