35x3 Set Preset Value. Writing this value to 1 signals the data radio to preset the counter with the value stored in Modbus registers
43504 and 43505. When the task is complete, the value is written to 0.
35x4 and 35x5 Counter Preset Value. Registers 43504 (high word) and 43505 (low word) contain the 32-bit value for presetting the
counter. Write the ‘Counter Preset Value’ registers first, then use the ‘Set Preset Value’ register to execute the counter preset.
43600s H-Bridge Output Parameters
The Power Output Configuration parameters provide the basic operation for each power output. These parameters are not associated to
specific inputs. Parameters for H-bridge 1 start at 43604 through 43609. Parameters for H-bridge 2 start at 43624 through 43629. Each
following switch power is offset from the previous one by 20 registers.

36x4 Enable H-Bridge. Enable (1) or disable (0) the h-bridge inputs as needed. Disable the h-bridge inputs when using SDI-12 devices.
36x5 H-Bridge Warm Up Cap Time. Similar to the switch power warm up time, the h-bridge capacitor warm up time is the time allotted,
in 40 millisecond increments, to charge the capacitor used to activate the h-bridge and latching solenoid.
36x6 H-Bridge Active Current Time. Set how long, in 40 millisecond increments, the capacitor is switched into and supplying power to
the solenoid circuit.
36x7-36x8 H-Bridge Switches. Use these two parameters as a bit mask to set the ON and OFF conditions of the h-bridge switch.

36x9 H-Bridge Booster Enabled When Active. To use this parameter, contact the applications engineers at Banner Engineering Corp.
This parameter leaves the boost voltage on while the capacitor discharges into the solenoid. While this can supply more power to the
solenoid circuit, it may also brown-out the radio device.
43600s Switch Power Output Parameters
Efficient power management technology enables some FlexPower devices to include an internal power supply, called switch power (SP),
that briefly steps up to power sensors requiring 5, 10, or 15V power (ideally, 4–20 mA loop-powered sensors). When the switch power
output cycles on, the voltage is boosted to the voltage needed to power the sensor for a specific warmup time. This warmup timedenotes
how long the sensor must be powered before a reliable reading can be taken. After the warmup time has passed, the input reads the
sensor, then the switch power shuts off to prolong battery life. The switch power voltage, warm-up time, and sample interval are configu-
rable parameters.
The Power Output Configuration parameters provide the basic operation for each power output. These parameters are not associated to
specific inputs. Parameters for SP 1 start at 43601 through 43603. Parameters for SP 2 start at 43621 through 43623. Each following
switch power is offset from the previous one by 20 registers.
