CHAPTER 3 BASIC OPERATION

The CNP888 is connected to the CobraNet audio system using its CobraNet interface,

so it is very easy to install. You don’t need to change the structure of the audio

system — all you need do is connect the CNP888 to the CobraNet audio system using

CAT-5 Ethernet cable, and then you can simultaneously process the audio channels

from the local analog input or from the CobraNet input using the NSP-100 software.

According to different application situation, it can divide into two modes: stand alone

mode and network mode.

3.1 STAND ALONE MODE

The CNP888 can work in stand alone mode as a small console, controlled by NSP-100

software. Recommend to use this mode in small audio system (the number of input

channel less than 8 and number of output channel less than 8)

In stand alone, connect the computer network card to the CNP888, whose functions

are controlled via dedicated software NSP-100, with cross-over cable. The operation

is listed below.

Step 1

Connect the computer network card to the CNP888 with cross-over cable, audio

source to the Line/Mic input ports at the rear panel and output equipment to the Line

output ports. The maximum length of the CAT-5 cable is 100m.

CNP888

stand alone mode

www.digispider.net

Step 2

Startup CNP888, and wait for CNP888 start to work in normal status with all LCD and

indicator lights turn light.

Step 3

Add the CNP888 into the NSP-100 software in a right way; please refer to chapter 3

“NSP-100 quick start for CNP888”.

Step 4

According to the situations, it is possible to adjust the DSP parameter of the CNP888

device via the NSP-100 software.

Step 5

Users can confirm the previous DSP parameter and next time can use CNP888

independently without computers.

3.2 NETWORK MODE

To satisfy the demands of large CobraNet audio system, the CNP888 can be used in

the Network mode.

In the network mode, the CNP888 can receive the audio signal from the CobraNet

audio network, and transmit the processed audio signal to the audio network or local

line output. The operation is listed below:

Step 1

Use the straight CAT-5 cable to connect the CNP888 device, CobraNet device and

control computer together with the switch. But it should be noticed that the length of

every single net cable is less than 100m as far as possible. The maximum length of

the CAT-5 cable between the switch and CNP888 device is 100m.

www.digispider.net

CNP888

Network mode

Step 2

Startup CNP888 device, and add every equipment into the NSP-100 software system.

Then, set up the receiving/sending relation between them. Please refer to chapter 3

“NSP-100 quick start for CNP888”.

Step 3

According to the situation, the function of the CNP888 can be controlled by the

NSP-100 software.

www.digispider.net

CHAPTER 4 NSP-100 QUICK START FOR CNP888

NSP-100 is an application software to design, edit, control the audio processing and

transmitting system constructed by the Digispider device like the CNP888 series,

TR2000 etc. NSP-100 is running on a standard Windows PC(Windows XP).After the

design and configure have finished, the audio system would operate normally, the PC

and the NSP-100 software could be removed.

Here is the brief introduction of the NSP-100 installment and application, if you want

to more detail information, please refer to the “NSP-100 user manual”.

Step 1: Install the software

1) Install the CNOT and WinPcap software.

CNOT and WinPcap software must be installed in advance prior to the setup of

NSP-100. If your PC have already installed these two software, it don’t need to install

again.

2) Install the NSP-100 software.

Note: the NSP-100 setup package would automatic install the CNOT and WinPcap

software at first.

Step 2: Launch NSP-100 software

Double click the NSP-100 icon on the desktop.

When the NSP-100 software is launched, a dialog box would display, requesting you

to enter the password for the user. The initial password is “1”.

www.digispider.net

Make sure the beginning IP and the end IP are configured within the IP range, of

which the first 3 segments of IP address are identical to that of the adapter, otherwise

the NSP-100 will not be started normally. After all configure have done. The

NSP-100 could be launched normally.

Step 3: Create a new project for the test system

Click the “File-New” to create a new project.

The main interface of NSP-100 after created a new project.
