RS485-Ethernet TCP/IP Converters

ModbusTCP

When Modbus electricity meters are read directly from the Teltonika manufacturer's LAN or 4G router, a Protoss-PE11 type RS485-Ethernet converter is used.

Since Modbus communication primarily occurs over an IP/TCP network, this is referred to as ModbusTCP, unlike Modbus RTU which simply uses an RS485 bus.

The RS485-Ethernet converter can also be connected to the Climkit gateway. Multiple converters can be used depending on the project configuration.

By default, the device is delivered pre-configured and ready to use with the Climkit router.

Default parameters:

Static IP address: 192.168.2.10

RS485 bus settings:

  • Baudrate: 9600
  • Parity: None
  • Data Size: 8
  • Stop Bits: 1

If the device has been factory reset, it reverts to DHCP mode, meaning the router assigns it a random new IP address. Refer to the router's configuration to find this address.

The converter is configurable via its internal web portal, accessible directly through a browser using its IP address. Login admin/admin.

The default configuration used by Climkit is as follows:

Mbus via TCP

The converter can also be used to read MBus devices via an RS485-MBus converter.

The parameters are the same as above, with the exception of:

  • Baudrate: 2400
  • Parity: EVEN
  • Protocol: None

If both Modbus and MBus devices need to be read via TCP, two RS485-Ethernet converters must be used: one for Modbus and one for MBus.
