Diver-NETZ Static FAQ

Below is a list of frequently asked questions for the Diver-NETZ Static. If you have a question that is not listed here please contact our technical support team.


Can I use my own FTP server?

Yes, you can use any FTP server. In the Diver-Gate(S) you can configure the address of your own FTP server. Van Essen Instruments can provide you with information regarding the requirements and steps to undertake this.

What are the requirements for a FTP server?

The FTP server must be a standard none secured FTP server.

What GSM frequency bands are used by the Diver-Gate(S)?

The GSM module of the Diver-Gate(S) makes use of the following frequency bands 850/900/1800/1900 MHz (Quad band).Frequency band 900 and 1800 MHz are used in most parts of the world: Europe, Middle East, Africa, Australia, Oceania (and most of Asia). In North America, GSM operates on the primary mobile communication bands 850 MHz and 1900 MHz. In South and Central America some countries use 850 and 1800 MHz.

Which mobile data services are supported by the Diver-Gate(S)?

The GSM module of the Diver-Gate(S) makes use of GPRS services (2.5G). GPRS is a wireless data transfer protocol that is used to connect mobile devices to the internet. It operates through the cellular network. To successfully use the Diver-Gate(S) device the telecom provider needs to support GPRS services.

Which SIM cards can be used?

By default Van Essen Instruments makes use of universal SIM cards. Universal SIM cards grant GSM services in nearly every country in the world generally at lower costs than other SIM cards. Van Essen Instruments can provide a list of GSM providers supported by the universal SIM cards in a specific country. Please be aware that the GSM provider still needs to support GPRS to successfully deploy Diver-NETZ Static. See also previous question.

Can I use my own local SIM card?

Yes, this is possible. Van Essen Instruments can provide you with information regarding the requirements and needed steps to configure the Diver-Gate(S) with local SIM cards.

Can I start/stop/reprogram a Diver with Diver-NETZ?

Yes, this can be done remotely. Van Essen Instruments can provide you additional information.

I do not have a radio connection between the Diver-Gate(S) and the Diver-DXTs?

Please follow the next steps:

  • From 07:00 PM to 23:00 PM the radio of the Diver-DXT will be in sleep mode to save battery capacity. Making a connection can therefore take more time (longer than 5 minutes).
  • Make sure you use the correct Network ID. For selecting the correct Network ID see the Diver-Mobile Manual.
  • The radio connection can be distorted by Wifi signals transmitting at the same radio band of Diver-NETZ
  • Check if the Radio LED on the Diver-Gate(S) is blinking during scanning and continuously on during data transfer. If not, the problem could be the Diver-Gate(S).

How can I power my Diver-Gate(S)?

The Diver-Gate(S) needs to be connected to an external power supply. This can be a lithium battery pack or a 12 V solar panel with a rechargeable battery.

No data is being transmitted by GPRS from the Diver-Gate(S) to the FTP server?

Please run the Diver-Gate(S) diagnostic tool (paragraph 7.4 of the manual).

The issue could be related to the following:

  • Lack of power. Make sure the external power is connected correctly to the Diver-Gate(S) and LED indicators start blinking when waking up the Diver-Gate(S).
  • SIM card not properly fitted. In this case the Diver-Gate(S) can not make a connection with the GSM network. Make sure the SIM card is properly fitted into the SIM card holder. The SIM card needs to be locked by sliding the SIM card holder into the fitting.
  • Configuration settings incorrect. Make sure the Diver-Gate(S) is properly configured (FTP settings, SIM card settings, network ID, wakeup time etc). The configuration of the Diver-Gate(S) can be checked in the overview LOG file created by the Diver-Gate(S) Configuration tool.
  • No GPRS coverage due to a lack of GPRS signal or due to a lack of data subscription with your own local SIM card. Please check the strength of the GPRS signal. This information can be retrieved from a communications log of the Diver-Gate(S). Please contact Van Essen Instruments for more information.
