* Default configuration. The default settings for D2 DIP switches 1, 3, and 4 are ON. This allows for forcing the device into client 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 acknowledgment/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 acknowledgment 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.
3.1.4. Transmit Power Levels/Frame Size
The 900 MHz data radios can be operated at 1 watt (30 dBm) or 0.250 watt (24 dBm). For most models, the default transmit power is 1 watt.
For 2.4 GHz radios, the transmit power is fixed at 0.065 watt (18 dBm) and DIP switch 5 is used to set the frame timing. The default position
(OFF) sets the frame timing to 60 milliseconds. To increase throughput, set the frame timing to 40 milliseconds. For battery-powered devices,
increasing the throughput decreases battery life.
: Prior to date code 15341 and radio firmware version 3.6, the frame timing was 40 ms (OFF) or 20 ms (ON).
