DCC203 is an interface between RS232, RS485 or RS422 bus and an Ethernet port. It converts between MODBUS TCP & MODBUS RTU. It has multiple master access on a single Ethernet port. This allows upto 12 masters to access the same devices on the serial bus. It can be configured as TCP Server or TCP Client. The browser based configuration utility allows the host IP address and serial settings to be changed.

The DCC203 module offers true IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) functionality using a standard category 6 Ethernet cable to receive power from a PoE switch such as the FS108Pv3. If there is no PoE switch on site, the module will also accept power input from a DC adapter.
