The older version of the MTB200 whose IMEI code is between
35946403600001X (ignore the last one parity bit X) and 35946403607338X
do not s pport the o tp t f nction, before sing the o tp t f nction, yo
sho ld check if the MTB200 is a newer hardware version.
The PIN9 on Mini-USB connector is a negative trigger o tp t in newer
hardware version, it is named as OUT PIN.
The o tp t is Open-Drain type with no internal p ll- p resistor which also
can be sed to control a relay. It means that the ser has to connect a p ll-
p resistor or a relay coil between the o tp t PIN and any positive voltage
(32V max.) to generate a correct o tp t. It can drive a maxim contin o s
c rrent of 0.15A.
For negative trigger o tp t the electrical conditions are:
Logical State Electrical State
Enable <0.4V, max. c rrent is 0.15A
Disable Open or the p ll- p voltage (max. 32V)
