Sierra Video RS-485 Pushbutton Control Panels - Manual (Page 19)

RS-485 PUSHBUTTON CONTROL PANELS
13
The two connectors on the back of the control panel are connected in parallel. This
allows the panels to be looped (“daisy chained”) together. If it is more convenient, you
can build a fan-out panel or box so that only one cable needs to run to each panel. In
either case, the total cable length cannot exceed 5,000 feet at 31,250 baud or 10,000 feet
at 9,600 baud.
If you make your own interconnect cables, Pin 2 is Ground. Pin 1 and 3 connect pin for
pin.
Warning!
Lights “scrolling” on a panel indicate that the panel is not communicating with the router. Check
the control panel cable and baud rate settings.
Output and Level Setup
The Sierra Video TyLinx Pro or MediaNav software programs are used to setup the
output(s) and level of the control panel. Refer to the TYLINX PRO or MediaNav manual,
“Control Panel, General Settings” sections of the manual.
Installation procedures are similar for all units covered under this manual. Exceptions, if
any, have been noted in each of the following paragraphs.
Collaborative Panels
It is possible for multiple single bus pushbutton panels to work together as a group to
form a single logical control panel. Panels working together are called collaborative
panels, and a collaborative panel is said to be operating in a collaborative mode. The
group that works together to form one logical panel is called a collaborative group. A
single router may have many collaborative groups connected to it.
An example of a collaborative group is two 16x1 control panels connected to a 32 input
router where one panel controls inputs 1 through 16 and the other panel is set to control
inputs 17 through 32 and the same output.
Each collaborative group of panels must be assigned panel ID’s that are grouped
together in a particular way which differs depending on the type of collaborative panel.
Each panel in a collaborative group shows up as a separate control panel in the router’s
list of active control panels.
CAUTION!
The same panel personality settings must be assigned to every panel in a collaborative group.
