Using the CW-Net in a user defined IP network
Data transmission and device control through IP platform CW-Net Basically, CableWorld's CW-Net operates in the 10.123.13.xxx IP address range. User Defined IP-Net CW-Net permits the user to operate the devices and the software in his own system, e.g. in the 192.168.1.xxx IP address range.
Connection of the device and the computer in the CW-Net network Checking up the connection: Set the IP address Click the Query button
Reprogramming the IP address of the device Steps of the reprogramming: Set the IP address of the device Type the new IP address in the box (+ Enter) Push the Replace IP Address button The result is shown in the message text box
Result of changing the IP address, if the device and the computer are in the same network Actual setting of the computer's Net Mask: 255.0.0.0 The device is still accessible (also with CableWorld software) It sends response to the Ping instructions
Result of changing the IP address, if the device and the computer are operated in different networks Actual setting of the computer's Net Mask: 255.0.0.0 The device is not available, the PC does not send out instructions The Ping instructions will not be answered
Reprogramming the computer for another Networks and features network TCP/IP features New IP address: 192.168.1.210 New Net Mask: 255.255.255.0 After the changes, in the new network there is connection with the device again, the Ping instructions are answered
Answer to the PING instruction, if the device and the computer are in the same network
Reprogramming the SW-4800 CW-Net Principal software to the new IP address range Steps of reprogramming the software and establishing connection with the device: Switch off using the basic setting of CW-Net Type the new IP address e.g: 192.168.1. Set the 4th byte Query the device with the Query instruction
After setting the IP address range, the network can be queried with the Auto Search button The speed of the query is adjustable The process of querying can be interrupted It is practical to put the devices on the IP Address List After this the parameters can be queried with the Query button Querying the devices in the IP network using Auto Search
Addressing a device of unknown IP address using the Broadcast message Note: the device of unknown IP address, possibily presumed to be defective can be queried with the Boadcast message: Set the 255.255.255.255 IP address and send out Query instruction For this operation the device should be connected directly to the computer
Retrieving the IP address with Broadcast message To be used in the case of forgotten or unknown IP address only Set the Boadcast adress (255.255.255.255) Set the new IP address for the device Send out the Replace IP Address command
The commands of the Auto Search mode inspected on the Ethernet analyzer
Controlling the device with the SW-4851 TS Remultiplexer and IP TV Server programming software Setting the SW-4851 software to the new IP address range: Setting the use of User Defined IP address Typing the first 3 bytes of the new IP address Setting the 4th byte in the Main Platform Sending out the Query instruction here or in the previous page
The main user interface of the SW-4851 TS Remultiplexer and IP TV Server programming software After setting the new IP address all features of the software can be used as in the 10.123.13.x range. At exiting with the Save and Exit button the settings will be stored, thus they do not need to be repeated at running the software next time.
Using the SW-4841 ASI to IP and IP to ASI Converter software Steps of programming and establishing connection with the device: Entering the IP address. Enroling the new address in the list using the Add button. Addressing the device by clicking its address in the roll-down list (sending out the Query instruction). The answer of the device is shown in the middle and the left or right hand side panel according to the device type.
Connecting IP networks using routers
Experiences Accurately built and right configured systems worked perfectly. Operating the system requires at least lower grade knowledge in computer technology. The simple but fast switches could be used well but configurable controllable swithes caused much trouble, presumable because even we are not professionals in building networks.
