Whistler EZ-Scan for TRX-1E 3.34.0.669
======================================

WHAT THIS IS
------------
Whistler's EZ-Scan programming software for the TRX-1E, version 3.34.0.669, as
the vendor's Windows installer (NSIS). EZ-Scan programs the scanner, prepares
the SD/microSD card, downloads the RadioReference Library and location
database, and checks for and installs CPU and DSP firmware.

Listed on Whistler's TRX-1E downloads page in November 2019; program file
dated 2019-09-27.

Library updates: the Library is RadioReference data, licensed to Whistler and
updated weekly through EZ-Scan's own update check. It is not part of this
archive. Updates stopped when Whistler closed (last Whistler-era build v894,
November 2024) and resumed under Goliad Products from about 2025-02-22, apart
from a one-day server outage on 2026-06-23/24.

APPLIES TO
----------
Whistler TRX-1E (international). Not for the US/Canada TRX-1.

BEFORE STARTING
---------------
- A Windows PC. The Windows versions supported were not stated by the vendor.
- The scanner's USB cable. The radio appears to Windows as a composite device:
  a card reader (no driver needed) and a serial port (needs the Whistler
  driver the installer places in Drivers\).
- A copy of the whole memory card, and a note of the CPU, DSP and Library
  versions, before any update.
- On a vehicle-installed base/mobile set, update on the AC adapter or a bench
  supply, not the vehicle circuit.

INSTALLATION
------------
 1. Run the installer and follow the NSIS setup wizard. The wizard's exact
    screens were not recorded.
 2. Install the USB driver from the installation's Drivers folder if Windows
    does not pick it up. The driver is unsigned; RadioReference owners report
    needing to disable driver signature enforcement on Windows 10/11 before it
    will install.
 3. Connect the scanner by USB. The memory card mounts as a removable drive;
    EZ-Scan finds it and the serial port.
 4. Use the program's update check to fetch Library and firmware updates. For
    firmware: power the scanner off before connecting; the platform procedure
    documented for the WS1080 family is Update > Check for CPU Firmware Update
    > Check for Updates > Update My Scanner, wait for "Done", then the same
    for Check for DSP Firmware Update.
 5. Eject the card drive in Windows before unplugging, and power off before
    connecting or disconnecting external power, or the card can corrupt.

VERIFYING
---------
EZ-Scan shows the program version in its About box and reports the connected
radio's model and firmware versions. On the radio, the CPU/DSP versions are
shown from the power-up welcome screen (see the CPU updater entries).

IF SOMETHING GOES WRONG
-----------------------
- "no removable drives found": the wrong EZ-Scan for the radio (for example
  GRE's software on an upgraded PSR-800), or the card not mounted.
- Card corruption during slow USB writes is a known problem on this platform.
  Update the card in a card reader instead; it is also faster.
- Windows Update replacing the USB driver, or only some USB ports working:
  reinstall the driver from the Drivers folder.
- A failed firmware update: hold MENU while plugging in the USB cable to force
  CPU update mode and retry, or use the standalone CPU updater for the model
  (in this archive).
- SSL or socket errors on update checks were seen when Whistler's servers
  lapsed in late 2024; they have worked under Goliad since February 2025.

DOWNGRADING
-----------
An older EZ-Scan can be installed over or instead of a newer one; the
installer does not block it. Older versions of this model's installer that
survive are listed in this archive's version table or in PROVENANCE.md.
Whether an older EZ-Scan reads a configuration saved by a newer one was not
documented.
