Communicating Via Modbus
Sealevel SeaI/O and SeaDAC modules are designed to integrate seamlessly into
existing Modbus networks. The supported command set will vary depending on the
SeaI/O model number used. Specialized diagnostic commands and other RTU
specific codes are not supported. An overview of the Modbus specification for both
RTU and TCP connections is covered in detail in the interactive documentation
located on the Sealevel website at:

The official Modbus specification can be found at:

NOTE:
SeaDAC Lite modules do not currently support Modbus commands.
