With iLive modular and V1.61 firmware, when connecting two MixRacks together for the Dual-MixRack function, do the Network Bridge jumpers need to be connected with ACE & Network in each of the MixRacks?
Would seem that ACE would need the control function on each MixRack for Dual-use.
To get the second rack joined up as a slave it has to be on the network, if you find it convenient to use the network bridge jumpers (using ACE in port-B) then fine.
They all have to have complimentary IP addresses or it could crash, the easiest way to do that is to probably change the IP address and name of the master rack from its default address (which is likely to be the same as the default in the slave-to-be) to something like 192.168.1.4.
Then you can use the Dual-Rack utility to add in and configure the slave rack.
(it gets inspected first to make sure it has the right firmware, port B kit, IP, & name).
Of course, you can use EtherSound or MADI to link the racks.
Interestingly, port-A becomes fully available on the slave rack in this mode, so we can have some fun with that, like using it to join to a monitor system in future :)
