MP-8/9 Link The AVP2 has the ability to control the operational status of the Madrigal Imaging
MP-8 and MP-9 video projectors in an intelligent fashion.
Specifically, when the MP-8/9 Link is turned on and the AVP2 is connected to
either an MP-8 or an MP-9 projector, the AVP2 can toggle the projector between
its operate and standby conditions according to whether an A/V source has been
selected on the AVP2. (There is a short delay prior to changing the state of the
projector, to guard against rapid toggling of the projectors status when acciden-
tally selecting an incorrect input.)
To take advantage of this feature with your Madrigal Imaging projector:
1 TOGGLE THE MP-8/9 LINK TO ON
2 CONNECT EITHER PHASTLINK CONNECTOR ON THE REAR PANEL OF
THE AVP2 TO THE CORRRESPONDING PHASTLINK INPUT CARD ON THE
PROJECTOR
Use a straight-through eight-conductor cable terminated in RJ-45 connec-
tors. This cable is outlined on page 29, in PHASTLink Control Ports.
Link Master When using the AVP in a PHAST home automation system, the PHAST con-
troller (that is, the computer running the PHAST software) must be the master
of the communications bus. It is responsible for passing all communications be-
tween various components in the system, much as the Post Office sorts out and
delivers the mail.
However, many Madrigal products also use the PHAST communications hard-
ware for their own inter-component communications, even absent the PHAST
controller. In these cases, one of the Madrigal products serves as the master of
the communications bus, facilitating all the communications between the various
components. In effect, absent a post office, one of the Madrigal products steps in
to deliver the mail.
At the risk of excessive anthropomorphizing, PHAST controllers do not like
such challenges to their authority. To prevent the AVP2 from attempting to be-
come the master of the communications bus when sharing it with a PHAST
control system, we suggest toggling the Link Master menu item to off, which pre-
vents the AVP2 from even enquiring as to whether it might take on these respon-
sibilities. If you do not have a PHAST controller, you may safely ignore this
menu item and leave it in its on setting.
