Fracarro SIG7120 Instrucciones De Uso página 21

To correctly install and configure the (SIG7120 or SIG7121) module, follow the operations listed below:
1. Install the module on the 19" sub-rack (SIG7901 or SIG7902) as explained before;
2. Use the supplied rigid jumper to connect the signal to other compatible New HeadLine modules (if present);
3. Connect the power supply to the 19" sub-rack;
4. Wait for the initialization of the module (the green LED flashes rapidly and the red LED is on);
5. Connect the TPE to the interconnection module of the 19" sub-rack and carry out the programming opera-
tions as specified in Chapter 5. PROGRAMMING INSTRUCTIONS.
IMPORTANT: The module needs about 30 seconds to complete the initial start-up phase and configure
the system; therefore, wait for the phase to be completed before starting any programming by means of
the TPE. Otherwise, the module might not be seen by the programmer and a new scanning of the head-
end could be necessary before being able to start programming it.
