2.7. External Output Interface
The older hardware version of the GL200 whose IMEI code is between 35946403600001X(ignore
the last one parity bit X) and 35946403607338X do not support the output function ,before using
the output function ,you should check if the GL200 is a newer hardware version.
The Pin 9 on Mini-USB connector is a negative trigger output in newer hardware version, It is
named as OUT pin.
The output is Open-Drain type with no internal pull-up resistor which also can be used to
control a relay. It means that the user has to connect a pull-up resistor or a relay coil between the
Output pin and any positive voltage (32V max.) to generate a correct output.. It can drive a
maxim continuous current of 0.15A.
For negative trigger output the electrical conditions are:
Logical State Electrical State
Enable <0.4V, max current is 0.15A
Disable Open or the pull-up voltage (max 32V)
The output examples are shown as following figures:
