3. D12 Firmware update
Note:
A firmware update erases all user settings of the device. The device
name and the log files are kept.
The operating software – firmware – can be updated in two different
ways.
1. Firmware update of a single amplifier via serial interface using the
dbUpdate software program.
2. Firmware update of multiple amplifiers via the d&b Remote network
(CAN-Bus) using the R10 Service software.
In addition, the d&b Firmware Installer is required.
All required software packages can be downloaded from the d&b
website at
www.dbaudio.com.
3.1 Firmware Installer
The Firmware Installer is a software program used to archive the
firmware files for the d&b amplifiers to a desired directory on your
computer. During the update procedure these firmware files are
accessed either by D6-D12-dbUpdate or R10.
3.2 D12 Firmware update via D6-D12-dbUpdate
D6-D12-dbUpdate is a control software for loading new firmware and/
or loudspeaker setups onto the D12 Amplifier.

To execute a firmware update the computer must be fitted with an
RS 232 interface (serial port) and a RS 232 extension cable must be
used (D-SUB 9 f/m cable with one to one connections between pins 2, 3
and 5).

Please refer to the computer manual for the pin configuration of an
RS 232 port that uses a D-SUB 25 connector.
3.3 D12 Firmware update via CAN-Bus and R10
Using the d&b Remote network and the R10 Service software a
firmware update can be carried out via CAN-Bus. R10 allows to update
the firmware of multiple devices connected to the network at one time.
Notes:
For further information on R10 and the firmware update via CAN-Bus
please refer to the R10 manual.
A detailed description of remote control via CAN-Bus is given in the
technical information TI 312 (d&b code D5312.E.).
