User Guides

Your Lomak (or Notesai) is a programmable device and has its own internal microprocessor which works very hard for you.

The microprocessor's program controls all keyboard and mouse communication with the host computer. This program is called firmware, because it is software held in an electronic memory which can be reprogrammed.

Additionally, the firmware is field reprogrammable, that is, the keyboard does not have to be returned to the supplier for upgrading, but can be upgraded by people who have been trained to do this task. Please contact your sales agent for advice and further instructions.

Lomak keyboards are fitted with circuit board revisions as follows (most recent first):

• Rev5 keyboards have Serial Numbers starting at K79. They operate with Rev5 firmware from v3.6 and above.
• Rev4 keyboards have Serial Numbers between K24 and K78 inclusive. They operate with Rev4 firmware from v3.3 and above.
• Rev2 keyboards have Serial Numbers between K1 and K23 inclusive. They operate with Rev2 firmware from v3.0 and above. Keyboards prior to v3.3 need to be returned to Opdo Limited for upgrading.

The serial number is printed on the top sticker affixed to the back of the keyboard.

The following firmware revisions are in active use (most recent first):

Plug the Lomak into a USB port on your Windows Vista computer. If you are a System Administrator, use the Windows Device Manager to report the current firmware revision, as follows:

• Open the Windows Explorer by any method. For instance, you might click Start, then click Computer on the list displayed on the right.
• Click the Properties button on the second row to open a window “View basic information about your computer”. (If this button is missing, click Restore Defaults on the Folder Options menu.)
• Click Device Manager in the task list at the left, then click Continue when challenged for permission.
• Scroll to the bottom of the Device Manager’s window and click on the “+” square to expand the entries for Universal Serial Bus controllers.
• Right click on the last USB Composite Device entry to display its context menu. Left click on Properties to open the USB Composite Device Properties window.
• Select the Details tab. Scroll down the Property list and select the Device Instance Path. Then continue with the section Device Instance ID strings below.

Plug the Lomak into a USB port on your Windows XP computer. If you are a System Administrator, use the Windows Device Manager to report the current firmware revision, as follows:

• Right click on My Computer (on the desktop, or in the Start list) to display the context menu. Left click on Properties to open the System Properties window.
• Select the Hardware tab and launch the Device Manager.
• Scroll to the bottom of the Device Manager’s window and click on the “+” square to expand the entries for Universal Serial Bus controllers.
• Right click on the last USB Composite Device entry to display its context menu. Left click on Properties to open the USB Composite Device Properties window.
• If the Location field does not show Lomak keyboard click Cancel to close the window and repeat for the previous USB Composite Device.
• Select the Details tab. It will display the Device Instance Id. Then continue with the section Device Instance ID strings below.

The Device Instance Id is a string similar to the ones below—if you do not see such a string, you are looking at the wrong device, so click Cancel and select another USB Composite Device.

Typical strings are:

• USB\VID_1451&PID_0320\V3.6_(C)2006
• USB\VID_1451&PID_0320\REV5_V4.1_(C)2006
• USB\VID_1451&PID_0320\REV5_V4.2_(C)2006_LOMAK

The firmware version is prior to the copyright year, e.g. V3.6, V4.1, V4.2 in the above examples.

From v4.1 onwards, the string also reports the hardware revision number of the keyboard’s PCB, e.g. REV5 in the above examples.
