Industrial Modbus TCP to 2 port Serial (232,422,485) RTU/ASCII Gateway 

Antaira Technologies’ STM-602C is an industrial MODBUS gateway that allows legacy MODBUS RTU/ASCII devices to operate on a MODBUS TCP network. It can be configured for either MODBUS serial master or slave to communicate with MODBUS TCP’s slave or master. The STM-602C features two independent Ethernet ports and MAC addresses to provide redundancy and reliability. These devices provide an economical way of connecting MODBUS RTU/ASCII devices to networks accessible anywhere in the world.
