Page 4: Introduction
Master/logger/data recorder and at least one slave (ModbusLink-S). Each Slave unit can be connected to one Modbus sensor via either a RS232 or RS485 port. If the ModbusLink-M is unable to reach a Modbus sensor directly, it will try to discover a route to the destination via intermediate ModbusLink-S modules. -
Page 5: Unpacking
Unpacking Unpacking Remove the ModbusLink-M and ModbusLink-S units from the shipping container and visually inspect the unit for signs of damage during shipment. Report any such damage to the factory immediately to ensure a prompt response and resolution. Retain one shipping container in the event a factory return is necessary. -
Page 6: Hardware Description
Hardware Description Connectors The ModbusLink-M/S modules support the Modbus protocol (RTU mode) over RS-232(default) or RS-485, selectable via a simple command. The external IP6 rated DB9 connector should be used for communication with Modbus loggers/Sensors using RS-232. For interfacing with a modbus logger/sensor over RS-485, a 5- terminal connector is provided. -

ModbusLink-S module with the same address in the network. If the destination node is not within radio range of the ModbusLink-M module, it will try to discover a route via intermediate ModbusLink-S modules. If multiple routes are possible to the destination, the most efficient route will be selected. - Page 9 If an intermediate node cannot deliver a message to the next hop, it informs the sender, which starts a new route discovery.
