Group and Unit ID settings
The MVS family uses fixed IP address, based upon the type of chassis. There are two settings that can be
changed by the end user. These are, primarily, to accommodate customers who have multiple switchers
on the same LAN or multiple individual chassis as part of the same system (for example 8 channels of
MVE-8000A DME will require two DME chassis, which will require different IP addresses.)
The two settings are Unit ID and Group ID. Both are set with DIP switches on the CPU card in each
chassis. Unit ID is the setting that tells the system there are multiple of the same chassis on the same
switcher system. For example, you have two DME chassis for 8 channels, each chassis holding 4
channels, one DME chassis would be set to Unit ID 1, the other to Unit ID 2. Another example is when
you have two control panels attached to the same switcher chassis. The first control panel would be set
to Unit ID 1, the second to Unit ID 2.
In the engineering Setup Menu, you will see a list of all switcher items that are discovered. You will see
items like SWR1, PNL1, DME1, DME2 (depending on your configuration). By the way, DME1 and DME2
are examples of two chassis being on a system, one being Unit ID 1 and the other being Unit ID 2.
If you have two completely separate control rooms, but they are both on the same switcher LAN, this is
where you set different Group IDs. Using a separate Group ID allows each control room to have
“proper” Unit ID’s without having to remember things like “DME4 is really DME2 in control Room 2”.
Typically a new switcher system delivered from the factory will have both the Group ID and Unit ID set
to 1 on all components. However, it is important to note that if you ordered more than one of the same
item (i.e. two DME chassis or multiple control panels), you must set the Unit ID’s before turning the
system on. We all know how computers love to have IP address conflicts. MVS is no different.
If you have purchased two complete switcher systems for two control rooms, you will need to plan out
which system will be Group 1 and which will be Group 2 and set the Group ID for the components
assigned to each room. Don’t forget the Unit ID settings also apply, as mentioned above.
Please refer to the installation manual on each chassis to determine how to set the Group and Unit IDs.
However, for a quick reference:
MVS-8000X is set on the CPU-82 board. Group ID is SW902 and Unit ID is SW903. Both can be accessed
from the front of the board. Typically they should both be set to 1.
MVS-7000X is set on the CPU-82A board. Group ID is SW902 and Unit ID is SW903. Both can be
accessed from the front of the board. Typically they should both be set to 1.
MVE-8000A is set on the CA-54CFC board. Group ID is SW102 and Unit ID is SW103. Both can be
accessed from the front of the board. Typically they should both be set to 1 unless you have two units.
If you have two units that will be used for the same switcher, set SW103 on one chassis to 1 and the
other chassis to 2. In the next section, Wiring, make sure to physically wire the DME chassis set to Unit
ID1 as DME1 (channels 1-4) and the DME chassis set to Unit ID2 unit to DME2 (channels 5-8).
MKS-8010B (SCU) is set on the CA76 board. Group ID is SW9107 and Unit ID is SW9106. Both can be
accessed from the front of the board. Typically they should both be set to 1. However, if you have
multiple control panels that will be used with the same switcher chassis, the unit ID must be changed to
be unique for each MKS-8010B.
