Disable Serial
If the local serial connection is not needed, disable it 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 4 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.
Prior to date code 15341 and radio firmware version 3.6, the frame timing was 40 ms (OFF) or 20 ms (ON).
Wire Your Sure Cross

Device
Use the following wiring diagrams to first wire the sensors and then apply power to the Sure Cross devices.
Wiring for DX80...E Radios
Connecting power to the communication pins will cause permanent damage. The integrated battery DX80...E radios may also be powered by 10 V
dc to 30 V dc. The power for the sensors can be supplied by the radio's SPx terminals or from the 10 V dc to 30 V dc used to power the radio. The
BAT connection is a low voltage connection to the internal battery. Remove the internal battery if a low voltage source is connected to the BAT
terminal. When powering the device from the integrated battery, the BAT connection must remain open.

Wiring Diagrams for Discrete Inputs
Connecting power to the communication pins will cause permanent damage. For the DX8
x...C models, PWR in the wiring diagram refers to V+ on
the wiring board and GND in the wiring diagram refers to V- on the wiring board. To power the sensor using the switch power output (SPx), replace
the PWR with SPx in these wiring diagrams.
