Network Poll Accelerator Crestron C2N-NPA8
Segments that are not in use or have devices that are not polled by a Crestron SIMPL
Windows program are logically ‘disconnected’ from the other segments in operation.
The LEDs for these segments are not illuminated.
To properly configure a network using a C2N-NPA8, the network traffic should be
balanced across the eight legs of the C2N-NPA8.
NOTE: The tips described below can be used as a starting point for balancing the
network traffic on most networks. Contact Crestron’s True Blue Technical Support
to determine the best configuration for your network.
Configuration Tips
•
Place ALL Cresnet devices on the segments of the poll accelerator and
nothing on the control system’s Cresnet bus.
•
Group all devices by device type and assign consecutive Cresnet ID
numbers.
•
Place devices on sequential segments of the poll accelerator in order of
Cresnet ID number (i.e. ID 03 on segment A, ID 04 on segment B, etc.)
Since the Cresnet network is polled by the control system in numeric order,
the control system will talk to different segments, allowing each segment to
process commands that overlap, instead of having to wait for the
completion of one command before going on to the next command.
Example
The following example is provided to show how a large amount of network devices
may be connected to the C2N-NPA8 for optimum performance.
A system has the following network devices:
•
Five TPS-3000L touchpanels. The touchpanels have been assigned with
Cresnet ID numbers 03 through 07.
•
Five CT-1000 touchpanels. The touchpanels have been assigned with
Cresnet ID numbers 08 through 0C.
•
Five TPS-4500 touchpanels. The touchpanels have been assigned with
Cresnet ID numbers 0D through 11.
•
Two C2N-IIF intercom interfaces. The interfaces have been assigned with
Cresnet ID numbers 12 and 13.
•
Three C2N-TXM satellite radio tuners. The tuners have been assigned
Cresnet ID number 14 through 16.
Using the configuration tips, connect the network devices as shown in the following
diagram.
