Description of the cabling to be made between DXT 3000 units connected in INTERLINK mode.
4.1. BUS INTERLINK
2 x CJ428CAT CABLES are needed for each connection between DXT 3000 units (redundant connection). The
INTERLINK Bus connections will be done on the IT 3010 boards of all DXT 3000 unit (IE 3008 if IT 3010 are not

is always the first DXT 3000 unit of the INTERLINK Chain.
