Uniden BC_VUP firmware updater 2.0.0.7
======================================

WHAT THIS IS
------------
Uniden's BC_VUP 2 firmware updater (installer dated December 2008), the
version Uniden linked beside the BCD396XT 1.07.00/1.08.14 and BC246T 2.60.00
firmware files. It writes a user-selected .scn firmware file to the scanner.

The zip holds a single self-extracting installer, BC_VUP_v2.0.0.7.exe. BC_VUP
2 installs into a "BCSS" directory and, when run, asks for a firmware .scn
file that the user has downloaded separately.

Uniden did not publish a change list for 2.0.0.7 against 2.0.0.3.

APPLIES TO
----------
BC_VUP 2 is model-independent; the .scn file determines the model. Uniden
paired 2.0.0.7 with BCD396XT firmware 1.07.00 and 1.08.14 and BC246T firmware
2.60.00.

Not for the BC350A or BC355N (no PC interface, no updatable firmware).

BEFORE STARTING
---------------
  - A Windows PC. Supported Windows versions were not stated by Uniden.
  - The firmware .scn file for the scanner (for example BCD396XT_V1_08_14.scn
    or BC-246T_V2_60.scn, both in this archive).
  - A serial connection: Uniden's USB-1 cable with its PL2303 driver, or a PC
    RS-232 port. Note the COM port.
  - The scanner's AC adapter and a backup of its programming.
  - Delete the install files of any earlier BC_VUP (in the "BCSS" directory).

INSTALLATION
------------
Uniden's procedure (BCD396XT firmware page, 2009):

 1. Unzip BC_VUP_v2.0.0.7.zip and the firmware zip to the desktop.
 2. Run BC_VUP_v2.0.0.7.exe to install the firmware updater.
 3. Run the installed BC_VUP application and follow the on-screen
    instructions. No registration key is needed.
 4. When prompted, select the .scn firmware file.
 5. When prompted, turn the scanner off, remove the batteries, and hold L/O
    and 6 while plugging in the AC adapter; the backlight comes on and stays
    on until the update ends.

VERIFYING
---------
Check the firmware version on the scanner. BCD396XT: MENU > Settings > See
Scanner Info > Firmware Version. BC246T: MENU > See Scanner Info > Firmware
Version.

IF SOMETHING GOES WRONG
-----------------------
  - Wrong COM port or a COM-port conflict causes almost every error.
  - Repeat the whole procedure, including the L/O + 6 power-up, after any
    error or interruption; the scanner recovers only when an update completes.
  - Uniden supports only its USB-1 adapter.

DOWNGRADING
-----------
Uniden does not document downgrading with BC_VUP 2. Whether it will write an
older .scn over newer firmware could not be confirmed.
