CPAT FLEX
Operation Manual (IRXP)
CPAT FLEX
Operation Manual (IRXP)
In some portions of the network, the coaxial cable is electrified and powers the active
devices located on that segment. In order to avoid electrical signal reflections, it is strongly
recommended to isolate the IRXP from the network using a test probe. The model illustrated
below operates in the 5 MHz to 1 GHz range, and introduces a - 20 dB attenuation.
The maximum RF level entry is 35dBmV in the RF input. This is however the total RF level
between 5~45 MHz.
If you want to combine nodes on the same RF entry, be aware that the IRXP sensitivity
performance might be affected: since the IRXP tries to detect ingress, the incoming digital
ingress signal is not always at the same level
CAUTION:
Levels over this limit can distort the signal or damage the receiver’s RF front-
end. Contact the CPAT technical support for more information.
5.2 Ingress frequency
IRXP supports three ingress frequencies: 6.78MHz, 27.12MHz and 40.68MHz. The frequency
is selected through the CPAT Web interface. IRXP checks for a new configuration only once
after booting.
5.3 Electrical
The AC/DC adapter is supplied with the equipment. It is compatible 110V/220V voltages and
50/60Hz.
6. System Operation
6.1 Power On
To power on the unit, press the ON/OFF button on the front panel. You should see the button
LED on the front panel turns yellow solid.
6.2 LED Information
The button LED indicates the status of the unit.
Power ON:
• When YELLOW solid, the system is booting (takes about 15 seconds to boot).
• When GREEN LED flashes three times per second, the FPGA is programming.
• When GREEN LED flashes twice per second, the cellular modem attempts to
connect to network.
• When GREEN LED flashes once per second, the system is ready to detect ingress.
Warning:
• When YELLOW LED flashed once per second, temperature is too cold (<-10°C) or
too hot (>55°C).
• When YELLOW LED flashed twice per second, battery is too low (<15% of charge).
• When YELLOW LED flashed three times per second, there are problems with files
transfer (SFTP).
Error:
• When RED LED flashes once per second, SIM card is missing.
• When RED LED flashes twice per second, battery voltage is lower than 6.95V and
IRXP is in shutdown process.
• When RED LED flashes three times per second, FPGA is not responding.
