Frame/Packet/Message Structure EthICMPdata ping EthIPUDPSNMPdata SNMP EthIPTCPFTPdata FTP Ethernet and IP protocols add information to data payloads to allow communications to occur in layers. Industrial Protocols like Modbus TCP/IP works the same way EthIPTCP MB hdrdata Modbus TCP/IP (Size in bytes)

SD4 and IP/Ethernet Data All IP connections terminate locally at the SD radio The transmitting SD extracts RTU data packet content and broadcasts it over-the-air The receiving SD regenerates the TCP/UDP data packet Makes efficient use of the channel, but has limitations SD radios dont route or bridge Ethernet data, it encapsulates industrial protocols in IP payloads
Latest Firmware Features
SD4 New Features New in the latest firmware revision for the SD series radios (release 4.1.5) –Extended Ethernet capability; supporting up to 3 simultaneous TCP/IP Client/Server connections to hosts and devices and ping over the air to remote devices bps –Extended Over The Air data speeds; now up to 19200bps on a simplex 12,5Khz channel. Double the previous rates. –Added maintenance functions e.g. reprogram remotes over the air, modem type, frequencies etc. –Simultaneous use of COM1, COM2 and ETH ports for data, acting like a full gateway for device connectivity. –WEB interface for easy programming with setup wizards –MAC network management with reduced overhead and guaranteed zero collisions over the air. –Store & Forward functionality for spectrum saving repeaters. –Terminal Server feature for Eth to Serial Conversion. –Full support for exception based protocols e.g. DNP3 & IEC /104.
