The older version of the MTB200 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 MTB200 is a newer hardware version.
The PIN9 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)
