General Information

About Megalinks Display Unit

This monitor is specially designed for use at shooting ranges. It is constructed around a 10.4” color LCD screen and is built to withstand hot and cold climate conditions. The monitor contains all the circuitry and software needed to communicate with the target and to register and display the position of each hit. The monitor controls are comprised of four (4) buttons mounted under the screen on the front panel which controls the displayed menu. The monitor requires only a single cable (carries both power and data) which is connected to a receptacle located at the firing position. Monitors may be serially connected to form a chain of two or more units (this is called a segment).

The monitor has been constructed in such a way as to be freely placed on the ground or on a stand. When the monitor is folded to a closed position the LCD screen is well protected.

The monitor requires a 12 volt power supply and each unit consumes a maximum of 0.7 amperes with full background lighting. The power needs of the unit make it very easy to run the whole firing position system with a 12V car battery if a fixed power source is not available.

**Overview

Buttons and Menus

Directly over each button on the front panel (marked A, B, C, D) are the screen function names. These names will change as different views are displayed on the screen.

For example:

Pressing button D in the screen opens the main menu. See picture

Buttons A and B can then be used to navigate up and down in the displayed menu. Button C is then used to make a selection from the menu. Button D can then be used again to close the menu and return to the main display.

Because of an error in the firmware versions FW=2.17 and FW=2.19 special procedure must be followed when upgrading. You must upgrade to software version 14.50 before continuing to the newest software version. Do not attempt to upgrade close to any mayor events. If the upgrade from one of these versions fails, please see section 4.3 Factory reset / software recovery.

Check what firmware currently is present in your monitor(s). This can be done by in the system status screen.
Delete all content on the monitor. Menu → Select Scorecard → Menu → Delete All
→ OK.
Use System administration in MLRange to generate an USB flash drive with the software version 14.50. Make sure to delete all data on, or format, the flash drive first!
a. If the current FW present is version 2.17, please select and copy the version 14.50 (FW.2.17) to the USB flash drive.

b. If the current FW present is version 2.19, please select and copy the version 14.50 (FW.2.19) to the USB flash drive.

Plug the flash drive in one of the available USB sockets on the rear of the monitor.
If the monitor is not connected to the range computer you can manually start the upgrading procedure by selecting Menu → System Settings… → Advanced → USB Upgrade. (Password value = 3).
If the monitor has not restarted after five minutes, toggle the power off/on by removing the power cord.
Check the system status screen that version 14.50 with FW=2.17 or FW=2.19 is present. If not, repeat step 3 – 7.
You are now ready to update to the newest version.

Factory reset / software recovery

If the monitor is not responding you will need to factory reset the software. Contact Megalink to get access to a downloadable zip file with recovery data.

There are two different types of Megalink color monitor. The previous type is called AT and the current is called IMX. Monitors purchased before 2016 are probably of type AT.

You can decide what type of monitor you are using:

IMX have the text DU3-IMX on the serial number label.

Replacing the Communications Circuit
If the communications circuit (Art.nr.5974) is damaged by lightning or other phenomenon it can easily be replaced (no soldering iron required).

Use fine pliers to gently squeeze the white card holder so that you can lift up the circuit board. Circuit boards should never be thrown in the trash. They are hazardous to the environment and should be disposed of in an appropriate manner.

Replacing the main Circuit

The main circuit can be replaced if a new one is provided by Megalink.
