CONNECTIONS
The MMk-736 has a group of communication ports that provide remote access to various types of
devices, allowing for it to be monitored and controlled (for more information regarding how to access
these ports, refer to the
M2M Communication Manual
).
The available connectors and their
pinouts
are indicated below.
4.1.
Power supply
1.9mm DC connector. 12V DC max input.
It is recommended to use the provided power supply with the
equipment.
4.2.
FXS (telephone line output)
Terminal block (pitch 5.08mm).
A maximum of four pieces of equipment can be connected
simultaneously.
4.3.
GPOs
Terminal block (pitch 3.5mm).
NPM open collector transistor
output. Maximum current in NPN
150mA pins per pin. Maximum
300mA.
These outputs can be activated or deactivated remotely via CSD and/or GPRS connections.
Furthermore, once the equipment is registered in the GSM network, it regularly checks the level
of coverage received. If, at any moment, insufficient coverage levels are detected lasting longer
than one minute, which is blocking a phone call from being made, the
OMSL NPN Collector - Out of
Mobile Signal
output will automatically activate. That way, the output can be used to notify the
lift's control panel that the emergency equipment is inoperative.

MMk-736 -
