a detailed installation guide in PDF format and a more detailed description of changes
that were made for this release. The download archive is available in either a ZIP (PC) or

Note that there is no need to update instrument firmware if it is working to your satisfaction. While an update may add or enhance features or remedy
instrument performance issues, it is inherently dangerous. Should the process fail
due to a loss of power or connectivity, the instrument will be rendered inoperative and
will require factory repair.

Highlights of changes are provided here.
- Scan Measurement Enhancements
- Added paper calibration during TID read for paper detection upon subsequent strip
readings.
- Added target stretch calibration during TID read for stretch tolerance during
subsequent strip readings.
- Added calibration data to TID scan for wider color tolerance during strip ID
recognition.
- Modified Red/Magenta and Blue/Cyan tolerancing to improve target color barcode
recognition.
- Battery Charging
- Fixed a battery charging situation, where if the cable is disconnected and then reconnected, battery fails to charge until unit is power-cycled.
- User-Interface Enhancements
- Modified FW forced resets now cause auto-wakeup if external power supply is not
connected.
- USB Enhancements.
- Alleviated intermittent USB enumeration failure during attach wakeup using DTP20
with low battery.
- Fixed transmit abort bug for gracefully recovering from unexpected USB disconnect
during data transfer.
- Fixed issue where having both the PC and a DTP20 with dead battery powered down
and then powering up the PC causes the DTP20 to go into SUSPEND shutdown and not wake
back up. Therefore, the battery will not recharge unless the USB cable is unplugged
and reattached.
- API Modifications
- Modified to always load factory default configuration upon reset.
- Removed MP command
