Application 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.
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.
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.
Receiver Slots
The number of receiver slots indicates the number of times out of 128 slots/frames the radio can transmit to its parent radio. Setting a slave’s
receiver slots to four reduces the total power consumption by establishing that the slave can only transmit to its parent four times per 128 slots.
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. Note that increasing the throughput
decreases the battery life.
Important: Prior to date code 15341 and radio firmware version 3.6, the frame timing was 40 ms (OFF) or 20 ms (ON).
