SERIAL TO ETHERNET CONVERTER WITH DUAL MASTERS

DCC211 is a Serial-to-Ethernet converter. It is an Industrial Terminal Server which functions as a gateway. It has two serial ports (RS232/RS485 slave, RS485 master) and an Ethernet port (master). It finds applications where a SCADA software, a PLC, an HMI or DCS need to communicate with a serial bus (RS232/RS485). Essentially, two masters can access data from slaves on one serial bus. For example, a SCADA software running on a PC is connected to the Ethernet port as master and an HMI is connected to the RS485 port as the second master. Both masters are able to access data from upto 32 devices on an RS485 bus, eg temperature scanners, connected to the RS485 port (slave) of the DCC211. DCC211 is an interface between an RS232 or RS485 bus and an Ethernet port. It converts between MODBUS TCP & MODBUS RTU. The web-based configuration utility allows the host IP address and serial settings to be changed. The DCC211 Converter 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 any PoE switch. If there is no PoE switch on site, the module will also accept power input from a DC adapter.
