CPU Firmware Update Release Notes

Version U1.2 - May 24, 2011
  • The USA bandplan has been adjusted as follows:

    Previous Band Plan:
    154.650000 – 156.255000 MHz, 7.500 kHz steps
    156.275000 – 157.450000 MHz, 25.000 kHz steps

    New Band Plan:
    154.650000 – 156.045000 MHz, 7.500 kHz steps
    156.050000 – 157.450000 MHz, 25.000 kHz steps

    This change resolves an issue with marine band channel 1 (156.050000) and 5 (156.250000) not falling into the scanner's bandplan.
  • Pressing left arrow key in SCAN mode now goes directly to Browse Objects mode, on the last object monitored.
  • Added option to show ONLY the RadioID's alpha tag for group calls. If this option set, you get just the tag (if one is available); otherwise, you get alternating tag / numeric ID.
    "Show Radio ID" "tag only" Result
    N - No Radio ID info shown
    Y N ID alternating with found tag (if any)
    Y Y Just the found tag, if any. If no found tag, just the ID
  • Fixed bug in search mode which was causing a crash if you pressed SKIP in Railroad mode.
  • Added "FlexStep" control to main Settings menu
  • Changed initialization code to address "freeze at startup" problem
  • Fixed backlight not turning off in KEY, IGNORE, and NORMAL modes when object alert is turned off (was staying on if the backlight was already on when the object alert went active)
  • Added TSYS index (i.e. "file number") to recording header
  • Fixed bug in priority talkgroup handling that would cause scanner to "lose" the current talkgroup in the Browse Objects, Play mode

Release Notes

Version 1.03 - May 24, 2011
New Features:

  • The USA bandplan has been adjusted as follows:

    Previous Band Plan:
    154.650000 – 156.255000 MHz, 7.500 kHz steps
    156.275000 – 157.450000 MHz, 25.000 kHz steps

    New Band Plan:
    154.650000 – 156.045000 MHz, 7.500 kHz steps
    156.050000 – 157.450000 MHz, 25.000 kHz steps

    This change resolves an issue with marine band channel 1 (156.050000) and 5 (156.250000) not falling into the scanner's bandplan.
  • Reorganized the Audio Recordings page with the recording data at the top, and more room for fields in the recording list.
  • Rebuilt the recording list on the Audio tab to gain consistency with the rest of the application.
  • Added new keyboard sequences and functions to the audio file list as follows:
    Up Arrow: When a single audio file is selected, will move the selection up one line.
    Down Arrow: When a single audio file is selected, will move the selection down one line.
    Enter Key: Start playing all selected audio files (same as clicking on the play button.)
    Esc Key: Deselect all selected audio files.
  • Added cancel button to the progress bar when reading the audio file data from the SD card. If the process is cancelled early, the file listing will be a partial listing.
  • Added Move option to the audio recording tab. This option will perform the copy to computer function after which all files that have been sucessfully copied will be deleted from the SD card.
  • This version provides much more control over the import process by way of an Import Settings button. This will provide all of the previous settings on the import process, and adds some new controls.

    The import options screen also allow you to set the options you select to be the new default settings.
  • When started, the EZ Scan Digital PC Application will attempt to determine if the drive it is run from is a USB device (i.e. Flash drive or external hard drive) and adjust the data path accordingly. This will allow you to take your data on a portable drive and use it in any computer.

    Note that in order to copy files to the SD card via the USB cable to the scanner, you will need to install the serial port driver on the machine you are using.

    To use this feature, copy the contents of the program folder (typically C:\Program files\GRECOM\EZ Scan Digital) to your USB device, and then copy the EZ Scan Digital folder from your My Documents folder into the same folder where you placed the program.
  • When using the Prepare card for use function from the SD Card menu, the list of audio files on the audio tab will be cleared since those files will be deleted during the SD card format.
  • Added two options to the Trunked System Line 5 display settings. These options allow you to see only the radio ID alpha tag (if it exists) instead of the previous Alpha Tag/Radio ID alternating (CPU Firmware U1.2 or later required).
  • Added option to enable flexible frequency entry (FlexStep)
  • Added option to change the order of trunked system sites to the trunked system tab. This option is only available on systems with two or more sites.
  • Added compress buttons to the Talkgroup and Radio ID sub-tabs on the Trunked tab. This option will remove unused space in the data files for the currently selected system. The recovered space depends on the number of ID of the objects that have been deleted from that data file.
  • Added select all and Clear All buttons to the scanlist selection area on the import screen.
  • When adding new talkgroups or radio IDs from the trunked systems tab, if the default "New Talkgroup" alpha tag has not been changed, it will be changed to match the talkgroup ID or radio ID entered.
  • When performing a DSP Firmware update, the PC Application will now check to ensure the scanner is not in CPU Firmware update mode and will notify the user to press the MENU key to turn the scanner off if it is. This prevents the accidental erase of the CPU firmware from the scanner.
Bug Fixes:
  • Fixed an issue where the first run screen suggesting viewing the help file would appear multiple times when the CDAT folder did not exist at program startup. Subsequent instances of the PC Application would not see this issue.
  • Fixed issue where the bottom of the scanlist page would not expand to fill the empty space when the PC Application is made larger.
  • Corrected an issue while saving information about a trunked system that could lead to data loss.
  • Fixed a display issue with delay time when sorting the talkgroup or radio ID listings on the Trunked Systems Tab and the delay time for an object is set higher than 25.5 seconds.
  • Fixed frequency entry issue when adding new conventional objects through the scanlist tab.
  • Fixed issue with entering frequencies when the bandplan setting was set to "Default".
  • Fixed positioning of the Trunked System Duplicate button when the application was increased in size.
  • Fixed issue that would not allow the PSR-800 PC Application run at the same time as the PSR-700 PC Application.
