1519 Target Utility Setup

Windows® Hardware Installation (USB Port)

The first time that you connect a target or the Radio Transceiver to a USB port on the computer, Windows identifies the device and automatically creates a virtual COM port. Connect the USB cable to the target or Radio Transceiver and then to any available USB port on the computer. The Windows Found New Hardware Wizard (see Figure 1 and Figure 2) displays a number of times.

Each time the Wizard displays, select:

  •  Install software automatically
  • Click Next
  • Wait for the next step to complete
  • Click Finish (see Figure 3)

Installing and Using the A-1519/1520 Type II Configuration Utility

The Configuration Utility is not required for normal operation. Hamar Laser pre-configures the targets with operating parameters that are suitable for most applications. The Configuration Utility is used for the following functions:

  • Firmware (Microprocessor program) Updates
  • Calibration Data Table Uploading (normally done by Hamar Laser. A Calibration Station is required)
  • Configuration of Internal Dampening Mode (Averaging)
  • Configuration of Background Light Periodicity Sync Frequency (50Hz/60Hz AC power line frequency)
  • Checking Firmware/Memory Status
  • Diagnostic Readout


  1. Click the Setup icon to install the utility.
  2. Follow the screen prompts and select the defaults. If prompted to replace existing files, always keep the newest files.
  3. After Setup completes, click Start>Program Files>Hamar Laser Utilities. Click A-1519 Type II Configuration Utility to start the program.

Users Database
The Configuration Utility uses a Users Database to assign permission levels to multiple users. Users must log in with a user name and password to configure the target, update firmware, etc. The person designated as the Primary Administrator on the computer should perform the initial software setup. The Primary Administrator has permission to add or remove users.

Initial Setup
Start the Configuration Utility Application. If it is the first time the application is initialized and a Users Database is not present, you will be asked to log in as a temporary user with administrator privileges. This temporary account is used to create the Users Database. Once the Users Database is created, the temporary account is deactivated.

Figure 4 – Initial Login Window showing access to user Database granted

Enter the following:
User Name: hamarlaser (not case sensitive)
Password: hamarlaser (case sensitive)
After entering the correct user name and password, the Users button is enabled (see Figure 4). Click on the Users button.


Figure5 – Users Database – Initialization



Editing the User Database
Upon initialization, the Users Database is blank and a Primary Administrator account must be created. Additional Users with three different permission levels may also be entered. Click Show Passwords to make the passwords visible on the screen as they are entered into the database (see Figure).

Permission Levels are as follows:

  • Primary Administrator (single account) This user has access to all program features and has permission to add and remove users.
  • Backup Administrator This user has the same access to program features as the Primary Administrator. Has permission to add and remove Additional Users only. Backup Administrators cannot make changes to the Primary Administrator account.

    Figure 6 – Example of Users Database with 5 User Accounts
  • Power User
    This user can access to all program features, but does not have permission to access the Users Database.
  • Operator
    This user has access to basic configuration features, but does not have permission to Update Firmware or Calibration Data and Critical Configuration parameters.
  • User Not in Database
    This user has access to Target Status and Diagnostic Readout only.


To edit the Users Database:

  1. Enter the Primary Administrator’s User Name and Password (twice)
  2. Enter any Additional User Accounts as needed.
  3. Click SAVE when you are finished adding users.





Figure provides an example of five user accounts, including one Primary Administrator, one Backup Administrator, one Power User and two operators.



Logging In

Figure7 – The Login Button


Figure 8 – The Login Window
  1. Click the LOGIN button (the following information refers to the sample Users Database shown in Figure ).
  2. Enter User Name (shown in Figure as Admin2).
  3. Enter the password for this user.
  4. Click OK. The LOGIN button changes to LOGOUT (see Figure ). If you log in with Administrator privileges, always click on the LOGOUT button or close the application when you are finished using it.
Figure 9 – Login Window with password validated

When a User Name is entered that exists in the Users Database and a valid password for that user, the OK button is enabled to indicate that the password is valid. Note that the Users button is also enabled because user Admin2 is a Backup Administrator with permission to edit the Users


To have the application remember your User Name and password for future login, check Remember Password (see Figure ). Do not check Remember Password when logging in with Administrator privileges because any user logging in afterward will have access to the Users Database.

Figure 10 – The LOGIN button changes to LOGOUT after successfully logging in to the program


Figure 11 – Auto-scan for targets

After the initial setup, you will be prompted to Scan COM Ports for Targets each time the Configuration Utility runs (see Figure ). Do not click YES until the target is connected to the computer and powered on by a scanning laser.


When a target is detected, one of the following messages displays.

Figure 12 – Target detected in Configuration Mode

Target Connected in Configuration Mode (Figure )

The target must be in Configuration Mode to perform the following functions:

  • Firmware updates
  • Change configuration parameters
  • Change application mode

When a target is in Configuration Mode, the status LEDs (see Error! Reference source not found., Front View) blink slowly, approximately once every three seconds.

Figure 13 – Target detected in Application Mode

Target Connected in Application Mode (Figure )
The target must be in Application Mode to be used with standard applications that require position information in standard packet format. In addition, Diagnostic Readout is only functional in
Application Mode.

When the target is in Application Mode, the Status LEDs (see Error! Reference source not found., Front View) will be lit continuously.


If a target is detected in Application Mode, you may also receive a message stating the Configuration Mode is not active (see Figure). Match the Serial Number shown in either message with the Serial Number on the target label. Click YES if the numbers match; click NO to search for other targets.

Figure14 – “Not in Configuration Mode” notification

If the Configuration Utility fails to detect the target, the NO DEVICES FOUND message box displays (see Figure ).

Figure 15 – Target Not Detected

Note: Normally a target should be present in one of the first 16 ports. Occasionally, however, particularly if you are connected through a USB Hub, Windows will assign a virtual COM Port number higher than 32.
Click YES to continue searching for target(s) on higher port numbers.
Click NO if you are sure that the target is connected to a port number within the range of the port numbers shown in the message box (see Figure ).



If you are sure that the target is connected to a port number within the range of the port numbers displayed in Figure , check the following:

  • Is the USB driver installed? If not, refer to the section titled Pre-installing the Common USB Port Driver (A-1519/1520 and A-910) SiLabs CP210x USB to UART Bridge Controller on Page Error! Bookmark not defined..
  • Ensure that the target USB cable connectors are fully inserted into the computer and target.
  • Ensure that the target is ON. The center LEDs (see Error! Reference source not found., Front View 2-
    1) should be lit continuously if the target is in Application Mode or blinking once every three seconds if the target is in Configuration Mode.
  • Ensure that the laser is ON and scanning across the position sensor (see Error! Reference source not found., Front View 2-4).
  • Click the SCAN PORTS button to rescan the ports (see Figure ).

Switching Between Normal Application Mode and Configuration Mode
