You can install two quad cards (VIS3-QUAD) as follows:
1.
The quad card in the slot furthest from the power supply is connected to quad
output A on the rear panel, and is controlled as monitor outputs 9–12. Note
that on a single unexpanded unit, these are extra to the eight monitor outputs
available on the rear panel.
2.
The quad card in the slot nearest the power supply is connected to quad
output B on the rear panel, and is controlled as monitor outputs 13–16. Note
that on a single unexpanded unit, these are extra to the eight monitor outputs
available on the rear panel.
You can connect two VIS3I-328 units together using a single expansion cable to
enlarge the video matrix node to 64 loop-through inputs by 16 outputs. When you
connect two units in this fashion, you need to set one unit to be the master unit in
the node and connect it to the Visilynx control network.
1.
Place the units one above the other in a rack cabinet or on a tabletop.
2.
Connect the rear panel expansion connectors using an expansion cable
(Type VIS3I-EXP).
3.
Set the Master-Slave switch on one unit to Master.
4.
Set the Master-Slave switch on the other unit to Slave.
5.
Power up both units together: the Master indicator should light steadily on the
Master unit front panel, and the Slave indicator should light steadily on the
Slave unit.
6.
From then on, the expanded node is treated as a single large unit, i.e. all the
configuration data is sent to the Master unit.
