Network Grouping
When multiple rack-mounted PIX video recorders (PIX 250i, PIX 270i, or PIX 260i) or the 970 Audio
Recorder are in use on an Ethernet network, they can be grouped together for transport control and
linking of most setup options. Setup Menu option
[Network - Network Group]
assigns the 970 to
one of four available groups.
In this section, the term “unit” refers to PIX 250i, PIX 270i, or PIX 260i Video Recorders, or the 970
Audio Recorder, unless otherwise specified.
There is no “master” / “slave” relationship in Network Groups. All units in a group are “master”.
Transport commands and settings changes made on any unit a group will ripple to all other units
in the group. If a transport command or settings change has to be made to only one unit in a group,
the unit must be temporarily removed from the group before making the change. To quickly toggle
between
No Group
and the current group setting, press MENU Control Knob.
Requirements and considerations when setting up Network Groups:
• The maximum number of units supported in a single group is currently 10. Increasing the amount
of units in a group increases the time of response for grouped transport commands and auto-con-
figuration.
• It is recommended that timecode be distributed individually to each unit in a group rather than
“daisy-chained” through units in a group.
• Allow all units in a group to auto-configure before proceeding with grouped operations. See the
following section for details. ( See “Group Auto-Configuration”, page 28 )
• Some settings are not linked even when units are in the same group. ( See “Grouped Settings”, page
27 )
Grouped Settings
A settings change of any unit in the group will be rippled through to all other units in the group,
with some exceptions. The following settings and functions will always apply only to the unit that
they are made on, and not ripple through to other units in the group (or be pushed when Setup
Menu option
[Network - Grouping - Push Settings to Group]
is used):
• All
[Network]
options.
• All
[Quick Setup]
options.

Pushing Settings to Group
When a unit is assigned to a group, none of its settings are immediately changed. Subse-
quent settings changes to any unit in the group will be applied to all units in the group. To
copy all settings from one unit to the rest of the units in the group, access Setup Menu option
[Network - Grouping - Push settings to group]
. This will copy all grouped settings to all other units
in the group.
