1. What is Included and Where to Start
The ADU208/ADU218 ships complete with a 10' USB cable, and this User Manual.
A complete Windows SDK including DLL, programming language examples (MatLab, LabView, Visual C, Visual Basic,
.NET, Linux, Python, OSX etc.), and our AduHidtest software is available at:
www.ontrak.net/programming.htm
First time users should first review the ASCII command set for the ADU208/ADU218 and then use AduHidTest USB
test software to become familiar with the operation of the various features of the product.
Note: The AduHid DLL requires one of the following Windows operating systems, Windows XP, Windows 7, 8, 10 or
higher. The programming section of the web site also contains examples for use with various other operating
systems, and provides details that allow use of the ADU208/ADU218 without using the Windows based AduHid DLL

3. The ADU208/ADU218 STATUS LED
The ADU208/ADU218 STATUS LED is a bi-colour (Red/Green) led indicator used to identify the status of the
ADU208/ADU218 USB connection.
The LED modes are;
RED -ADU208/ADU218 powered but not enumerated.
GREEN -ADU208/ADU218 powered and enumerated by host computer.
OFF -ADU208/ADU218 disconnected from USB bus.
The ADU208/ADU218 can be connected to the USB bus via the enclosed 10' A-B USB cable. The cable provides
both power and communications connections to the ADU208/ADU218. When first connected, the STATUS led will
turn RED indicating power is applied. For Windows operating systems, a message may flash on the screen
indicating;
New hardware Found
ADU208/ADU218 USB Solid-State Relay I/O Interface
Depending on the version of Windows, the host may prompt to search for a driver. Select,
Let Windows Search for a Driver
and click next.
After several seconds, the STATUS led will turn green indicating enumeration is complete. The enumeration
process is completely transparent to the application program as the ADU208/ADU218 is a low-speed USB HID class
device. Enumeration is completed by the Windows (or other) operating system using standard USB HID drivers.
The ADU208/ADU218 can be connected directly to the host hub or externally powered hubs.
Caution: (Use of System Sleep): If the operating system allows the host computer to
enter sleep mode, attached USB devices will be set to suspend mode. In suspend mode
the ADU208/ADU218 relay outputs remain in their last state. Ensure system power
settings are set such that the host computer does not enter sleep mode during normal
operation.
Caution: If the operating system USB Selective Suspend is enabled, after the
ADU208/ADU218 is physically connected and enumerated (LED Green), the host may
suspend the connection if no handle is opened to the ADU208/ADU218. In suspend
mode the ADU208/ADU218 relay outputs remain in their last state.

4. AduHidTest USB Device Test Program
AduHidTest is a Windows based USB device test program used to test the connection of ADU data acquisition
devices to a USB port. The program is also a useful tool to allow programmers to become familiar with the
ADU208/ADU218 command set before programming in other languages. AduHidTest software can be
downloaded from the Ontrak website at: www.ontrak.net/programming.htm . Note that the program requires
the AduHid.dll to operate and it should be copied to the same directory as the AduHidTest.exe file.
There are three steps in using a USB device in any application software. The three steps are;
1. Obtain a handle for the USB device.
2. Send commands to the USB device.
3. Receive data from the USB device.
STEP 1: Obtain a handle for the ADU208/ADU218
A handle is a unique code that application software uses to identify a USB device for the purpose of reading and
writing to the device. A USB bus can have up to 128 devices connected to a single host and there are three
criteria that can be used to open a handle. The three criteria are, Vendor ID, Product ID and Serial Number. If a
single device is connected to the bus, any of the three criteria may be used. If multiple devices are connected, we
recommend using the Serial Number to open the handle.
(All ADU devices have their unique serial number printed on the top label.)
Figure1 shows the AduHidTest software opening window.
Figure 1: AduHidTest Software Window

Page 7 of 18 ADU208/ADU218 User Manual
The Open/Close section of the window is where the handle is determined. Click on the Show List button to view
the devices connected to the USB bus. (Note: Only ADU devices will be listed ) Figure 2 is the window that appears
when the Show List Button is clicked.
Figure 2: ShowList Window
The window indicates that there is one ADU208 connected with serial number C31784. Select the device by double
clicking on the text “ADU208 serial number = C31784”. The AduHidTest main window will now display the product
ID and Serial number. Click the By Serial # radio button and then click Open to open the handle to the selected
ADU208. Figure 3 shows the AduHidTest window with the handle open to the ADU208.

STEP 2: Sending Commands to the ADU208/ADU218
Once connected, you may now send commands to the available "pipes" on the ADU208/ADU218 device. Pipes are
the individual connections to functional sections of the ADU208/ADU218. The Device Pipe is used to send standard
ASCII ADU commands to control the peripherals built into the ADU208/ADU218. The ADU208/ADU218 does not
use the RS232 or Stream pipes. Type "SK0" (set relay K0) into the device pipe send window and click Send ADU.
An OK will appear beside the Send ADU button if successful, as shown in Figure 4, and the ADU208/ADU218 relay
K0 will close. Note that ADU commands are not case sensitive.
Figure 4: Sending "SK0" Command

STEP 3: Receiving Data from the ADU208/ADU218
Some commands cause a response to be sent from the ADU208/ADU218 back to the host computer. For example,
if an "RE3" (read event counter on PA3) command is sent, the ADU208/ADU218 will send back the value of the
event counter. To read responsive commands, simply click the Receive ADU button and the data will be displayed.
Figure 5: Sending "RE3" Command
Figure 6: Receiving Data
The received data indicates Event counter 3 is at 62 counts. These procedures can be repeated using the various
commands available on the ADU208/ADU218. The AduHidTest software is an invaluable tool to allow
programmers to become familiar with ADU commands before programming in various other languages and/or
operating systems.
