Thuraya T2M-DUAL
4.7 GPIO PORT
The T2M-DUAL has 8 I/O ports that can connect with external sensors.
I/O Ports 1 to 4 are digital ports that can be set to input or output using the T2M-DUAL
management tool.
I/O ports 5 and 6 can be used as digital ports or analog ports. When used as digital
ports they can be set to input or output using the T2M-DUAL management tool. In case
they are used as analog ports they are can only be set to input using the T2M-DUAL
management tool.
The T2M-DUAL contains two serial (UART) ports. In case the UART ports are used, the
necessary UART protocol should be implemented.
The table below shows the I/O port summary.

4.8 OVER SPEED ALARM SETTING
Over speed alarm setting invokes the terminal to ring the buzzer continuously when the
vehicle exceeds the set speed limit.
4.9 SHOCK LIMIT SETTING
The impact value of the built-in impact sensor can be configured differently for each user.
IGN On and IGN Off time shock limit value can be set differently.
4.10 SPEED, RPM AND BRAKE COEFFICIENT SETTING
For vehicles that do not support CANbus, it is possible to measure the speed, rpm and
braking data of the vehicle using analog speed sensor and rpm sensor signals. This
signals are different for each vehicle manufacturer; the installer needs to adjust the
appropriate parameter coefficient.
