Uniden BC_VUP firmware updater 2.0.0.3
======================================
WHAT THIS IS
------------
An early build of Uniden's generic BC_VUP 2 firmware updater (installer files
dated April 2008), still listed on Uniden's download site. It installs an
updater that writes a .scn firmware file to the scanner. Superseded by
2.0.0.7.
The zip holds a single self-extracting installer, BC_VUP_v2.0.0.3.exe. BC_VUP
2 installs into a "BCSS" directory and, when run, asks for a firmware .scn
file that the user has downloaded separately.
APPLIES TO
----------
BC_VUP 2 is model-independent; the .scn file determines the model. Which
scanners' .scn files this early build accepts could not be confirmed; Uniden's
BCD396XT and BC246T pages linked 2.0.0.7 instead.
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_v2.0.0.3.zip and the firmware zip to the desktop.
2. Run BC_VUP_v2.0.0.3.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.
