Here are some diagnostic activities that must be carried out “on site”, or in telephone contact with technical personnel in the field who can inform about the status of the Rilheva peripheral.
- There is no LED on to indicate the presence of electricity: check for the presence of power at the ends of the terminals “supply”. The supply voltage (DC or AC) must be between 11V and 26V.
- Does the led “GSM NET” NOT flash briefly? Is it off or on fixed? Under normal conditions of attachment to the GSM network, the led gsm net must make short interspersed bursts continuously. If this does not happen, it means that the peripheral cannot register to the GSM network. Verify the validity of the SIM by inserting it into a mobile phone, verify the correct insertion of the SIM into the “sled” with the gold contacts facing down, verify the antenna connection (that it is screwed in tightly and in a free field), verify that there is a GSM field of that operator. To test the GSM field set dip switch 2 to ON and all others to OFF and the led sequence will indicate at “bar graph” the GSM field strength. In case of insufficient GSM field, it will be necessary to change the position of the antenna (it must be positioned outside free from obstacles, in a vertical position, with a metal ground base and must not have the cable bent or severed) or connect a GSM antenna with a higher gain. In case of a directive antenna (e.g. YAGI) it will be advisable to polarize it vertically and point it towards the nearest BTS cell or at least perform a retry pointing. At startup, the peripheral will perform a series of operations distinguished by a specific flashing LED. When the operation is successful, the LED becomes fixed and the next LED flashes.
- The peripheral has the first LED on flashing: this means that the hardware initialization phase of the device is underway.
- The peripheral has the second LED on flashing and the first on fixed: this means that the registration phase to the GSM network is underway.
- The peripheral has the third LED on flashing and the first ones on fixed: this means that the connection phase to the GPRS network is underway. If it fails to pass this stage, check GPRS coverage, verify that your SIM is enabled for GPRS traffic by entering it into a GPRS mobile phone and trying to connect to the internet (email or browser). In the case of some telephone operators, it is also necessary to use the fields “user” and password” possibly configured during the Rilheva activation phase to access internet services. Consult your telephone operator for more information on activating your SIM’s GPRS service.
- The peripheral has the fourth LED on flashing and the first ones on fixed: this means that the connection phase to the Xeo4 server is underway. If it fails to pass this stage, you must wait for the DNS to align and the server to accept a connection.
- The peripheral has the fifth LED on flashing and the first ones on fixed: this means that the authentication phase to the Xeo4 server is underway. If it fails to pass this stage, it means that the peripheral has not been registered at the server level. Contact Technical Support or the authorized distributor. Once finished, all 5 LEDs will be turned on fixed together with the LED “SERVER CONNECT” turned on fixed and the LED “GSM NET” turned on flashing, indicating the correct connection status to the Xeo4 server.
