Firmware Upgrades; Firmware Upgrades Using The Update Utility - Lab.gruppen PLM Series Operation Manual

12 APPLICATION GUIDE
users should experiment with cable lengths in
rehearsal situations to discover what maximum length
can be used, and then to not use more than 75% of
this length "on the road". It is also good practice to
ensure that interconnect cables (particularly mixer-
stage) of various lengths are available, and to use the
shortest that each venue will permit.
It is also recommended that the same types of cable
and connectors are used throughout the system,
as this will minimize any likelihood of impedance
mismatch. If passive splitters are used, they should
be situated as close as possible to the PLMs (or other
devices) connected to their outputs, using cables as
short as possible.

12.6 Firmware Upgrades

This chapter describes the process for upgrading
firmware in the PLM.
As responsible manufacturers, Lab.gruppen and Dolby
adopt a policy of continuous product development. As
with all software-based products, it may be desirable
from time to time to update the firmware in your
PLM with a more recent version. You can contact
your Lab.gruppen dealer or distributor, or visit the
Lab.gruppen website at
http://www.labgruppen.com/plm for details of
available updates.
Firmware upgrades are downloadable from the
Lab.gruppen website.
PLM firmware upgrade is conducted via the network
from the PC running the DLC PLM Edition software.
There are two methods of performing the upgrade:
by using the Firmware Update Utility or by using the
DLC PLM Edition software.
12.6.1 Firmware Upgrades Using the Update
Utility
The Firmware Upgrade Utility allows fast upgrade
for large networks of Dolby Lake-equipped products.
Follow the steps shown below to use this method
for firmware upgrade.
1. Install the latest version of Dolby Lake Controller
PLM Edition software on the Tablet PC normally
used to control the system.

2. Power on all PLMs and connect to the PC using
a wired network.
3. On the PC, go to start > All Programs > DLC
PLM Edition software Vx.y > Firmware
Update Utilities > PLM series FW update
utility (where Vx.y represents the current
version of DLC PLM Edition).
4. If the PC is configured with multiple network
adapters, select the required network adapter
from the displayed list and tap OK.

Please select and use a wired networks
with a fixed IP address for performing
firmware upgrades. A loss of network
connectivity could result in a failed firmware
upgrade.
5. The PLMs on the network will appear in a list
with their current firmware versions displayed.
The firmware version to be loaded is shown at
the top of the screen (Target firmware); this will
default to the latest version available. Highlight
the Frames that require updating.
