* Default configuration
The default settings for D2 DIP switches 1, 3, and 4 are ON. This allows for forcing the device into Master mode and DXM
menu control for the radio power settings.
3.1.1 Application Mode
The MultiHop radio operates in either Modbus mode or transparent mode. Use the internal DIP switches to select the mode
of operation. All MultiHop radios within a wireless network must be in the same mode.
Modbus mode uses the Modbus protocol for routing packets. In Modbus mode, a routing table is stored in each parent
device to optimize the radio traffic. This allows for point to point communication in a multiple data radio network and
acknowledgement/retry of radio packets. To access a radio's I/O, the radios must be running in Modbus mode.
In transparent application mode, all incoming packets are stored, then broadcast to all connected data radios. The data
communication is packet based and not specific to any protocol. The application layer is responsible for data integrity. For
one to one data radios it is possible to enable broadcast acknowledgement of the data packets to provide better
throughput. In transparent mode, there is no access to the radio's I/O.
3.1.2 Baud Rate and Parity
The baud rate (bits per second) is the data transmission rate between the device and whatever it is physically wired to. Set
the parity to match the parity of the device you are wired to.
3.1.3 Disable Serial
Disable an unused local serial connection to reduce the power consumption of a data radio powered from the solar
assembly or from batteries. All radio communications remain operational.
