Crestron C2N-NPA8 Network Poll Accelerator

Network Poll Accelerator:

C2N-NPA8

Introduction

Features and Functions

The Crestron

Network Poll Accelerator (C2N-NPA8) is a device that maintains

high data throughput and low data latency via Cresnet

when a large number of

Cresnet devices communicate with a single 2-Series control system. When connected

to select Crestron 2-Series control systems via a high speed serial or Ethernet

connection, the C2N-NPA8 can provide reliable, high-speed communications

between the control system and up to 252 Cresnet devices.

Functional Summary

• Reliable, high-speed communications between select Crestron 2-Series

control systems and up to 252 Cresnet devices

• Eight segments with four mini-Cresnet connectors per segment

• Independently operated segments provide fault tolerance should an

individual segment fail

• Communicates with select 2-Series control systems via high-speed

serial or 10/100 Base-T Ethernet (refer to “Compatible Control

Systems” on page 6 for a list of compatible control systems)

• Console function to configure device settings and monitor diagnostics

via DB-9 RS-232 connector

• Each Cresnet ID can be viewed with the Network Analyzer

Placing a large amount of Cresnet devices on a control system can slow down

polling time as each Cresnet device is polled sequentially by the control system. By

breaking down the Cresnet system into segments, multiple segments can be polled

simultaneously by the control system, hence improving response time.

Similarly, high-traffic devices such as touchpanels, camera controls, and other

devices require more network bandwidth as they transmit and receive larger amounts

of data. By placing these devices on their own segments, other segments can be used

for low-traffic devices such as wall keypads allowing Cresnet traffic to flow more

efficiently.
