11 START-UP AND CHECK
Once you have prepared the TRM-300 integration according to the previous sections, you can switch on the
computer and the radiomodem, according to section 9.3.3.
Programming Kit accessory, which includes the T2PRO_Programming Guide, is needed in order to configure
the terminal according to the TETRA network. The terminal will be operative when it has successfully
registered on the system. In case of detection of error mode, check that the terminal is properly programmed.
The TRM-300 has two indicator lights on the Main_PCB, one on each side and both showing the same
information. They indicate the Terminal status regarding TETRA operation, according to the following table:
In case of a TRM-300 configuration with GPS, a third indicator light is present on the GPS_PCB.
It indicates the Terminal status regarding to GPS operation, according to the following table:
PowerTrunk recommends its Maintenance Kit accessory, which allows to verify:
- The integration critical aspects (by means of the sensors located into the TRM-300):
o Operating temperature. See section 8.
o Operating supply voltage. See section 9.
A specific test allows measuring the voltage under the circumstance of standby mode
(maximum voltage) and the voltage under the circumstance of transmitting at full power
(minimum voltage), which is sufficient to verify if the power cable length and the power supply
are appropriate.
o TETRA Antenna RF impedance. See section 10.1.
Besides, the previous test provides an approximate value of reflected power under the
circumstance of transmitting at full power, which is sufficient to verify if an antenna of the
same frequency band as TRM-300 is connected.
- TETRA Antenna installation:
o Registration information.
o RF power in transmission.
o Frequency and RSSI in reception, together with neighbour cells information.
