Aware Electronics Corp. LCD-90 Pro Firmware Updates

Following is a list of firmware updates for the LCD-90. To find the LCD-90's current firmware version, turn the LCD-90 on by pushing the On-Off button. The LCD-90 will show a startup message and then will begin displaying the radiation level. The startup message is as follows: First "STARTUP" is displayed, the RM is powered up and the LCD-90 code searches through its flash memory to build file pointers. Next "AWARE ELECTRONICS V24B" scrolls out where V24B equals the firmware version number i.e. V24B stands for version 2.4B. Note if the USB cable is plugged in, the LCD-90 will cut short the "AWARE ELECTRONICS V24B" scroll and instead display "USB ON".

If you have an older version firmware and would like to update it, return the LCD-90 to Aware Electronics Corp. and we will program it with the latest firmware. E-mail or phone us for instruction on how to return the LCD-90 for firmware update. The service is free.


V2.4B includes two new features. Regarding CONTROLLING AND GATHERING DATA FROM THE LCD-90 IN ASCII FORMAT USING OTHER PROGRAMS we added the following ASCII command:

P causes LCD-90 to immediately send the same number that is being displayed on the LCD-90’s display, followed by the tab character, followed by the UNIX time code, followed by carriage-return line-feed.

Also added is the following feature:

A note about the LCD-90's clock display when its internal UNIX time code is set to less than or equal to 1000000000 (Sat Sep 08 21:46:40 2001):

To match Aw-Radw's method of cancelling out any effect of variation between local time and GMT, the clock display routine within the LCD-90 first subtracts 18000 from its internal UNIX time, before the clock routine displays the time, as-long-as the UNIX time is greater than 1000000000 (Sat Sep 08 21:46:40 2001). If the LCD-90’s UNIX time code is set to less than 1000000000, the clock display routine will not subtract the 18000. This allows a clock display that starts at zero hrs. zero minutes, zero seconds when its internal UNIX time code is set to zero.


V2.3B corrected the following: When turned off, the LCD-90 left the Geiger "click" circuit powered up such that one might hear Geiger clicks even if the LCD-90 was turned off.

Also corrected the following: When turning off the LCD-90, if one did not release the On-Off button very soon after the LCD-90 turned off, it would turn on again. This has been corrected such that one has at least one second to release the On-Off button, after the LCD-90 turns off, before it will turn on again.
