AT Modem Emulator, User Module allows B+B SmartWorx Powered by Advantech routers to emulate telephone modem behavior. The modem can receive a dial-up request via the serial port and convert it to a TCP/IP connection. A device connected to the router’s serial interface sees the router as a HAYES-compatible modem. The serial device can use standard AT commands to establish the connection, configure the parameters and terminate the connection. A router connection can be established with another B+B SmartWorx router or any TCP/IP management platform located at the Master end.
This means that legacy dial-up equipment that was designed only for modem access can now communicate transparently to its corresponding software application across a cellular or Ethernet interface. Further the B+B SmartWorx router enables the migration of the legacy equipment to an all IP solution at a later date without any hardware changes.

Protocol MODBUS-TCP2RTU – converts MODBUS TCP protocol to MODBUS RTU protocol
This user module converts the MODBUS TCP protocol to the MODBUS RTU protocol, which is typically run through the serial port.The router can use either PORT1 or PORT2 as a serial expansion port for RS-232 or RS-422/485.
DNP3 Outstation – implementation of DNP3 protocol
The DNP3 Outstation module allows the router to use DNP3 protocol (Distributed Network Protocol v3), which is intended for reading data from the router. The primary purpose of this protocol is the mutual communication between devices in a network.
