Image 6-50: Cabling between an E2 unit and two EX units
When an EX unit has VPU cards rather than a combination of Input and Output cards, and it is
connected to an E2 processor or to an S3–4K processor, the EX unit an no longer be daisy-chained
to another EX unit; both Link connectors on the EX unit must be connected to the E2 or S3–4K
Master unit.
How to Link an E2 Unit to Two EX Units, Each with a Mixed I/O/VPU Configuration
To add up to eight Single Layers or four Mixing Layers to a system, an E2 unit can be linked to two EX units,
each with a single VPU card. This adds two VPUs. The VPU can be in either slot 1 or slot 2 on the EX unit,
and the other slot may contain either an Event Master Input card or an Event Master Output card. Each E2
comes equipped with two Link cards, always located in slots 1 and 2. Link cards are identified by a yellow
stripe at the top. Each EX has two Link sockets. Make sure to use the locking mechanism and then push each
cable until it locks in place.
To link an E2 to two EX units, connect the Link cables provided with each unit between the Link connectors as
follows:
• E2 VP ID 0, Link Card slot 1, Link 1 >> EX VP ID 1, Link 2 [1]
• E2 VP ID 0, Link Card slot 1, Link 2 >> EX VP ID 1, Link 1 [2]
• E2 VP ID 0, Link Card slot 2, Link 1 >> EX VP ID 2, Link 2 [3]
• E2 VP ID 0, Link Card slot 2, Link 2 >> EX VP ID 2, Link 1 [4]
See Image 6-51 for an example of the cabling between an E2 unit and an EX unit with a VPU card and either
an Event Master Input card or an Event Master Output card.
