Upgrading unit software
Note that this procedure can only be done one unit at a time – it is recommended that the unit being updated is
disconnected from any RS485 network until the procedure is complete.
Connect the unit to upgrade to a spare COM (serial) port on your PC or laptop. The serial cable must be a “one-to-one”
cable and NOT a null modem cable. This is because a null modem cable has “transmit” and “receive” wires swapped, and
so will not work. It is also possible to upgrade through an appropriate USB to RS232 converter, if your computer does not
have serial ports. The software cannot be updated via RS485.
Make sure the unit’s interface is set up as Master
5
on RS232 and ID1, and that the baud rate is the same as that chosen in
the loader program (default is 38400). In the case of a DP6i, set the interface to
00. Plug the other end of the serial lead
into the RS232 port on the unit.
Run the loader program from the ‘Software’ folder on the CD called “Load226.exe”.
Select the correct COM port and baud rate, and press the
‘CONNECT’ button. If all is well, the loader will display
details of the connected unit.
At this point, press the “…” button beside the “File” text
box, and choose the correct bin file (selection will have
been automatically limited to software for the unit type
detected).
Do not switch off the unit during this procedure or attempt to run other software on the
computer. If the upgrade is interrupted, the unit will become inoperable and may have to
be returned to the factory.
Finally press the ‘Load Now’ button (which previously said ‘CONNECT’), and the unit will display

The number nnnn will count up in sync with the number on the loader software and, when complete, the unit will reboot
and display the new version number and the message

In the case of the DP6i, the unit will reboot and flash nS (“new software”) to show that the update has been successful.
The entire process will take less than two minutes.
