Unit Firmware Updates


The downloadable file below contains firmware updates for the DP548, DP448 (and all 4 Series units), DP226, DP224, DP6i and SiDD (DP324).It also contains the necessary flash loader utility to perform the update via the unit's RS232 port ONLY.

Click on a version number in the table to see the revision history for that product.

Note that some older versions of firmware are available in this history section - linked items may be clicked on and the zip file containing the software downloaded.

Please remember that updates to DC1048 are bundled with the latest version of iCore so download that to update your unit if required.

This new loader is required to recognise the DP428. Note that the DP428 is updated to the DP448 with this software version. No memories or settings will be lost in this process. The zip file also contains the last updates to the DP224, DP226, DP6i, SiDD (DP324, and Series 2 processors (C2, G2, D2, E2 - one file for all four units).

Please follow the instructions carefully. If you are unsure about what to do, do nothing and give us a call - we'll be only too happy to talk you through the process.

Requirements:
A PC running Windows 98SE/ME/2000/NT/XP/KP/WALKERS
A cable to connect from a free RS232 port on the computer to the 9 pin DEE connector on the unit.

Instructions:
Copy the file UPGRDXTA to an empty or new directory.
Unzip it: this will cause it to extract the latest binary firmward files (.bin) and an exe file. Running the exe file will start the loader program.

Note that for a DP6i, the interface MUST be set to Master RS232 mode ID 1 at the same speed as the loader running on the PC (interface numbers 00, 02, or 04, for 38k4, 19k2 or 9600 baud respectively). For the DP548, 4 Series, DP224, DP226 and DP324, the interface must similarly be set to Master on RS232 at the correct baud rate.

For the Series 2 products, the RS232 interface is AUTOMATICALLY CONFIGURED TO RUN AT 38400 BAUD.

Warning! Close any open programs. Any interruptions, internal or external during the download process can cause the unit to become inoperable (including a reattempt at download).
