FIRMWARE UPDATE
6.1. Introduction
Firmware can be updated in the field through the USB port allowing feature upgrades and bug fixes. The
USB port is located on the rear side of the unit. Thus, if the unit is rack mounted and access to the rear
panel is hindered a USB extension cable may be attached to the USB port and lead through the front.
6.2.
Installing the PC Updater Software
Firmware update is supported by a PC based updater tool. Download this tool from our Website.
Installation of the PC Updater is through a standard Windows installation packet. Double click on the
single installation packet file and follow the instructions provided on screen thereafter.
6.3.
Updating Firmware
To update firmware the unit has to be put in a special service mode.
Attach the USB cable only after entering the service mode.
This is achieved by pressing the right key on the front panel and keep pressed at power up or reset.
Release the right key button after power is applied or the reset key is released.
The reset key is accessible through a small bore in the lower left corner of the front panel.
To power down/up the unit the mains cables have to be removed and attached again. Obviously, this is
less convenient. The unit indicates it is in service mode when the power down/up method was used by
an Updater Mode message in the front panel display. When using the reset method the front panel key
preserves the information that was present prior to reset and the standby key is highlighted red. Other
key illumination is switched off.
This user manual complies with firmware revision 182 build 9593. Prior or later firmware revisions may
deviate in details or lacking of newly introduced features.
