A.1 Accessories
There are accessories, which can enhance the
usefulness of the controller.
External Battery Temperature Sensor
(DT or DTB)
The DT is a plastic-cased unit for direct attachment
to the battery case. The DTB has a bolt-on lug for
attaching to the battery terminal (either terminal).
The unit connects to the T+ and T- inputs on
the green plug in terminal block under the wiring
cover. See Section 7.4.3 for further details about
this unit.
The following accessories plug into the serial port
socket which is under the wiring cover.
External Shunt Adaptor (DSA)
Up to four external shunts can be added to the
Dingo to allow it to measure larger currents than it
is capable of measuring directly. The shunt adaptor
measures the current in a shunt (eg SH200), converts
it to digital information and sends that information
back to the Dingo. The connection to the shunt is
DC isolated from the Dingo so the shunt can be
placed in any part of the circuit. Currents up to
+/-250A can be read in 0.1A steps. See the DSA
instruction sheet for more information.
Computer Serial Interface (DUSB)
A serial interface is available which allows the Dingo
to communicate with a computer. It connects to
the computer’s USB port. The computer side is DC
isolated from the Dingo side.
This is a quick way to load settings into the Dingo or
extract performance data. All of the data is remotely
accessible, and all settings can be adjusted. Software
is available for IBM compatibles to make this easy.
Data can then be loaded into a spreadsheet or other
applications.
Modem Serial Interface (D232)
The serial interface is also available in a version
designed for remote access via a modem. This uses
an RS232 interface configured as a DTE device.
A
Remote Control (DRC)
The Dingo can be accessed remotely with the
remote control. All of the functions work in the
same way as on the actual controller. Includes
built-in audible alarm and display backlighting.
This unit is still under development at this time.
