Using Multiple Control Panels
The 8150 Signal Chassis can connect to and communicate with multiple
Control Panels. All Control Panels connected to a Signal Chassis are in
communication with that chassis, but only one panel has control of that
chassis. Control Panels that are not transmitting to the Signal Chassis are
still receiving, and show the current status of all crosspoint buttons,
transition control buttons, and menu displays.
Physical Connections
Each Control Panel has two 9-pin connectors labeled CONTROL IN and
CONTROL OUT. These connectors are wired together to create a passive
loop. To connect more than one Control Panel to a Signal Chassis,
connect the supplied Control Panel cable or a standard RS-422 cable
from the Signal Chassis CONTROL PANEL port to the CONTROL IN
port on one of the Control Panels. Next, connect another RS-422 cable
from the CONTROL OUT port to the CONTROL IN port on the next
Control Panel. Continue until you connect all Control Panels.
Acquiring and De-Acquiring Control
When a single Control Panel 8150 system powers up, the Control Panel
automatically lights its
ACQUIRE
button (right side of the Control
Panel), indicating that it has control of the Signal Chassis. Double
pressing this button turns off the LED and disables control. The Control
Panel still communicates with the Signal Chassis: it receives, but does
not transmit. A single press of the
ACQUIRE
button reestablishes
control.
When a multiple Control Panel 8150 system is first powered up, no
Control Panel controls the Signal Chassis. Press the
ACQUIRE
button
on any panel to gain control of the Signal Chassis. As long as a Control
Panel is acquired, no other Control Panel can have control.
To de-acquire a Control Panel, double press the
ACQUIRE
button to
turn off its LED. At this point, you can acquire any Control Panel by
pressing its
ACQUIRE
button once.
Once a multiple Control Panel system is operational, rebooting or power
cycling any Control Panel or the Signal Chassis maintains the
acquire/de-acquire status of each Control Panel, and it does not need to
be reconfigured.
