AML LDX10 - Troubleshoot Manual

To Next Page

The LDX10, TDX20 and M7225 mobile computers, can all be configured to communicate with a

computer using its USB connection in one of two ways:

• Serial over USB

• WMDC (Windows Mobile Device Connectivity)

First, let’s determine the device’s current communications method. Exit out of DCSuite on the device by

tapping on Settings and then Exit. Double tap on the ‘My Device’ icon on the desktop and navigate to the

‘\Windows\Startup’ folder. If “DCSuite” is the only shortcut listed in that folder, continue following the

steps below. If the only shortcut listed is “SuiteCommunications”, jump to the section titled

“SuiteCommunications is listed in the Startup folder” on page 3.

DCSuite is the only shortcut listed in the Startup folder:

This will indicate the device is using WMDC as its communications method. On the computer, press the

Windows key and type in “Device Manager” and select the app once its displayed. In Device Manager,

check and see if the device is listed as a ‘Microsoft USB Sync’ device under a section labeled “Mobile

devices”.

1.) My device is displayed as above, but the DC app does not show it as being connected:

With this being the case, then there would be some Windows services needing their properties

modified. Press the Windows key, type in ‘Services’ and select the app when its displayed. Look

for the following two services:

For each of these two services, set their Log On properties as displayed below:

Once that is set on both services, stop the Mobile-2003 service if it is running. Then stop and start

the Windows-mobile-based device connectivity service. Once that service is running, Start the

Mobile-2003 service. Disconnect the device from the computer. Run the DC App being used on

the computer and select the Sync tab at the top. At the bottom, set the USB Port mode as seen

here and then connect the device to the computer. It should be shown as connected.

Troubleshooting the LDX10/TDX20/M7225

Do you have a question about the AML LDX10 and is the answer not in the manual?

The AML LDX10/TDX20/M7225 mobile computers are versatile devices designed for communication with a computer via a USB connection, supporting both Serial over USB and Windows Mobile Device Connectivity (WMDC) methods. This document outlines comprehensive troubleshooting steps to address connectivity issues, ensuring seamless operation and data transfer.

Function Description:

These mobile computers are primarily designed to facilitate data collection and processing in various environments. Their core function involves capturing information and transmitting it to a host computer for further analysis or integration into larger systems. The choice between Serial over USB and WMDC communication methods offers flexibility, catering to different system configurations and user preferences. Serial over USB provides a direct, low-level communication channel, often preferred for its simplicity and robustness in certain industrial applications. WMDC, on the other hand, offers a more integrated and feature-rich environment for managing the device, including file synchronization, application deployment, and remote debugging, leveraging the Windows Mobile platform's capabilities. The device's ability to run DCSuite, a dedicated application, further enhances its functionality by providing a specialized interface for specific tasks, streamlining workflows and improving operational efficiency. The internal software architecture allows for the installation and management of various applications, making the device adaptable to a wide range of business needs, from inventory management to field service operations.

Usage Features:

The user experience with the LDX10/TDX20/M7225 is designed for ease of use and efficient operation. When connecting to a computer, the device's communication method is a key factor. If the device is configured for WMDC, it will typically be recognized as a 'Microsoft USB Sync' device under 'Mobile devices' in the computer's Device Manager. This allows for straightforward synchronization and data exchange through the Windows Mobile Device Center. For users preferring Serial over USB, the device will appear under 'Ports (COM & LPT)' with an assigned COM port number, enabling communication through serial port emulation. The DC App on the computer plays a crucial role in managing these connections, allowing users to select the appropriate USB mode (WMDC Legacy or AML Serial USB) from its Sync tab. This flexibility ensures compatibility with different host systems and software configurations.

Navigating the device itself is intuitive. Users can access settings and applications by tapping on the 'My Device' icon on the desktop. The presence of 'DCSuite' or 'SuiteCommunications' shortcuts in the '\Windows\Startup' folder indicates the device's primary communication setup, guiding users through the appropriate troubleshooting paths. For instance, if 'DCSuite' is the sole shortcut, it signifies WMDC usage, prompting checks of WMDC services and drivers. If 'SuiteCommunications' is present, it points to Serial over USB, directing users to verify COM port assignments. The ability to manually convert the device's communication method from WMDC to Serial over USB, by deploying a 'SuiteCommunication.CAB' file, provides an advanced option for users who require a specific communication protocol or encounter persistent WMDC issues. This process involves copying the CAB file to the device's \Temp folder, installing it, and then configuring the DC App on the computer to use 'AML Serial USB' mode. This level of control empowers users to tailor the device's connectivity to their exact requirements.

Maintenance Features:

Maintaining optimal connectivity and performance for the LDX10/TDX20/M7225 involves several key maintenance features and troubleshooting steps. When WMDC connectivity issues arise, a primary focus is on the Windows services related to mobile device connectivity. Specifically, the 'Windows Mobile-2003-based device connectivity' and 'Windows Mobile-based device connectivity' services need to be correctly configured. This includes setting their 'Log On' properties to 'Local System account' and ensuring 'Allow service to interact with desktop' is checked. The ability to stop and restart these services, particularly the Mobile-2003 service, is a critical maintenance action that can resolve many common connectivity glitches. This ensures that the underlying communication infrastructure is functioning correctly.

Driver management is another vital aspect of maintenance. If the device is displayed as an "unknown device" in Device Manager, it often indicates missing or corrupted drivers. The troubleshooting guide directs users to check for updates via Windows Update, specifically looking for 'Microsoft USB Sync' drivers. Installing these drivers is essential for the computer to correctly recognize and communicate with the mobile computer. Furthermore, if all software-based troubleshooting fails, the option to reload the device's firmware is provided, with instructions and firmware files available on the AML website. This is a more advanced maintenance procedure that can resolve deep-seated communication problems by restoring the device's core operating system.

For persistent Serial over USB issues, particularly when the device is seen as "unknown" in Device Manager, a physical reset mechanism is available. The device features a small reset button, accessible with a paper clip, which can help re-establish communication. After a reset, momentarily connecting and disconnecting the USB cable can prompt the computer to re-detect the device. The guide also suggests trying different USB cables and ports, or even an externally powered USB hub, to rule out hardware-related issues. These practical maintenance steps ensure that users have a comprehensive toolkit to diagnose and resolve connectivity problems, minimizing downtime and maximizing the operational lifespan of their AML mobile computers.
