Multiple video head connections
Two.or.more.AdderView.CATx.units.can.be.
connected.together.so.that.they.operate.in.a.
synchronised.manner..Synchronised.operation.
is.useful.for.applications.that.require.multiple.
video.signals.to.be.switched.together..This.type.of.
operation.is.usually.required.where.each.computer.is.
fitted.with.multiple.video.cards.or.video.cards.with.
multiple.video.heads..Whenever.a.AdderView.CATx.
channel.is.switched,.it.sends.an.RS232.command.out.
on.its.serial.interface.(marked.
COM1/UPGRADE
.on.the.rear.panel)..
An.AdderView.CATx.will.switch.its.channel.if.it.receives.the.
same.command.on.its.serial.interface..Consequently,.by.linking.
the.serial.interfaces,.a.master.unit.may.be.made.to.automatically.
switch.one.or.more.slave.units.as.shown.in.the.diagram.
It.should.be.noted.that.the.synchronisation.cable.deliberately.does.not.have.
the.transmit.pin.of.the.Slave.End.connector.linked.to.the.receive.pin.of.
the.Master.End.connector..To.do.so.would.cause.the.Slave.unit.to.be.able.
to.switch.the.Master.unit..This.would.setup.an.endless.cyclical.switching.
sequence.that.would.prevent.the.AdderView.CATx.devices.from.operating.
correctly..For.more.details.about.the.serial.synchronisation.cables,.see.

The local user ports can also
be used to view multiple
video head installations.
Notes
It is recommended that the
second CAM in each pair is a
USB-type and that it is plugged
to a vacant USB port on the host
computer to derive its power.
Pairs of CAMs can be strapped
back-to-back with cable ties to
create a tidy installation...
