OPERATING PRINCIPLES

of Interface converter ZET 7177

ZET 7177 CAN→GSM interface converter can be used under conditions when there is no access to regular connection over Ethernet, or when you need to provide a redundant channel in case of Ethernet fouling.

For work, you need SIM card (MicroSIM) with Internet access, and Internet server (PC with external IP-address, accessible for connection over Internet). ZETLAB software must be run on Internet server; which is to accept incoming connections from Interface converter ZET 7177.

Interface converter ZET 7177 collects data from transducers connected to CAN bus, and transmits them to Internet server over 3G network. Data transmittance is conducted in real time mode. ZETLAB software is provided with functionality, which allows collecting, displaying and analyzing the data received.

ZET 7177 interface converter uses 3G network only for Internet connection. Voice calls, SMS and MMS messaging are not involved.

DATA TRANSMISSION FLOW

Several ZET 7177 modules can be connected at a time in single CAN network. This enables enhancing reliability of data transmission in case of troubles with mobile connection quality or with access to Internet server. For instance, you can arrange several parallel connections to various Internet servers or with SIM-cards of various operators.

SETUP PROCEDURES

for Interface converter ZET 7177

Adjusting SIM-card

SIM-card is not a part of module supply package, so you have to purchase it separately, or use the one you already have.

The module can work with SIM-card of any Russian cellular operator. Module uses the card for Internet access only; it involves no other services (voice calls, SMS or MMS messaging).

Each operator has his own parameters for Internet access: name of access point (APN), user name and password. You can enquire these parameters from the operator, by telephone or at the company website.

Requirements to prepaid traffic per month depend on total time of module connection to Internet server, and sum frequency of data output for all transducers. For instance, with module full-time connection and 200 Hz sum frequency, traffic is not more than 3 GB a month, and with 500 Hz sum frequency — 8 GB maximum.

Adjusting Internet server

Any IPv4 external address PC operating under Windows Vista OS or higher can be used Internet server.

As the PC must be accessible for connection over Internet, it is recommended to preliminary configure network display (firewall) to protect PC against external network attacks. The module is connected to Internet server using TCP/IPv4 protocol, so to run module you just have to permit incoming connections to TCP port with number 7176.

Also, ZETLAB software must be installed on PC, ZETKey must be inserted in USB slot, it is supplied with module to activate Internet server function in ZETLAB software.

Only one module can be connected to one Internet server at a time. Several servers can be used as a standby.

Adjusting module

Module and measuring transducers are adjusted only locally, using CAN wizard. Remote configuration of settings over Internet server is prohibited for safety purposes.

The following data must be input in module parameters:

  • Internet server connection mode: permit or prohibit;
  • Internet access parameters for the SIM-card used: name of access point (APN), user  name and password (if any);
  • TCP port number for connection to Internet server: 7176;
  • Internet servers’ parameters: one or more IPv4 addresses.

When more than one IPv4 address is specified in parameters, module will try connecting each of defined addresses in turn, until connection is set over one of them.

Features

Parameters of ZET 7177 interface converter (APN of cellular operator, Internet server IP address and so on) are configured locally, using ZET 7174 or ZET 7176 interface converter.
