D2B
The DXM Configuration Software allows the user to adjust parameters that govern the operation of the DC latch outputs.
Most applications will not require any changes for correct operation. Software parameters include:
•
Enable H-Bridge
—Enable or disable the H-bridge output. Default Enabled.
•
Voltage
—The voltage applied to the output when the output is activated. Default 13 V dc.
•
Cap Warmup Time
—The amount of time given to charge the output capacitor. The more time given to charge the
output capacitor the more energy will be available to turn on the output. Default 80 ms
•
Switch Time
—The amount of time the output is turned on to be able to change the solenoid output. Default 40 ms
5.9.6 SDI-12 Interface for the B2 and S2 Models
The SDI-12 interface on the B2 Wireless Controllers can support up to five
devices with twelve 32-bit register values each. The SDI-12 interface can
be configured to increase the number of registers per device address for
devices with large register sets. The factory default enables one SDI-12
device using device address 1 with up to nine registers with a SDI-12
command of "M!".
Use the configuration software to adjust the SDI-12 parameters.

Basic SDI-12 Interface Parameters
Up to five devices/commands can be accessed using the SDI-12 interface. There are three parameters for each device/
command: Enable, Device Address, Device Command. For more information, refer to the SDI-12 Technical Notes.
Enable
. Instructs the DXM device to activate or deactivate the SDI-12 device. Write a 1 to enable, and write a 0 to disable.
The factory default for device 1 is enabled; devices 2 through 5 are disabled.
Device Address
. Each SDI-12 device must have a unique device address. This parameter is the ASCII code for the device
address. Valid device addresses are
0–9
and
a–z
that map to ASCII codes
48–57
and
97–122
, respectively. The factory
default addresses are:
•
SDI-12 Device 0 uses ASCII code 48
•
SDI-12 Device 1 uses ASCII code 49
•
SDI-12 Device 2 uses ASCII code 50
•
SDI-12 Device 3 uses ASCII code 51
•
SDI-12 Device 4 uses ASCII code 52
Device Command
The SDI-12 interface supports "M!" or "C!" commands. Use the Device Command parameter to define
which command to use for this device. The factory default is "M!" commands for all devices (value of 10 in the Modbus
register).
