Titan – Example Scenario 2.10: Accessing data from an electronic meter via a GSM data call (Iberdrola, Endesa, etc.) and via GPRS, giving priority to the GSM call made by the company. Also, obtaining remote access to a network analyzer using an Ethernet port via Modbus TCP

Details of the example scenario:

• We need to provide Internet access to a network analyzer with an Ethernet interface. We must be able to access it in the TCP502 port given that it is a Modbus TCP meter. The meter’s LAN IP address is 192.168.1.70
• On the other hand, we have an electricity meter with an RS232 port with the configuration 9600bps 8N1. The data from this meter should be accessed using a transparent GPRS-RS232
  gateway, for which we will use the TCP20010 port
• The energy provider (Iberdrola, Endesa, etc.) must also be able to access the electricity meter via a typical GSM (CSD) data call. When the operator access the data, the GPRS connection will be suspended until the call is terminated

Solution: MTX-Router-Titan mini

Configuration example ready for use:

We can easily load the example from the router’s web configuration environment from the menu “Other>Backup/Examples”.

Details:

1. After loading the configuration on our router, we can access the router’s configuration with the default username and password: “admin” and “admin” and the IP address “192.168.1.2”
2. Check the configuration in the menus “Wan>Basic Settings”, “LAN>Basic Settings”, “Firewall>NAT”, “Serial Settings>Serial Port 1”
3. Remember that the router can only be configured to accept CSD calls when the router is in fixed GPRS mode. It is not possible when in 3G mode
