3.4 Communication network

The control unit is connected to the MM8000 system by means of the NK8000 network

and namely via the NK82xx units.

In order to communicate with the control unit, the NK82xx units should however be

equipped with a new firmware that is included in the installation package as an

additional component (DLL) to be added to the standard firmware file set.

The software installation procedure provides to copy the firmware files (a compressed

ZIP archive) in the NK82xx – Firmware folder of the MM8000. From there, the files can

be downloaded to the NK82xx units using standard Composer commands. The

required procedure is described here below.

3.4.1 Downloading NK82xx firmware

The following are the download procedures for the NK82xx firmware supporting the

control unit communication protocol.

Note: It is assumed that the NK82xx are physically installed, powered on, and

communicating over the network. For more information about the NK8000 installation,

please see the document no. A6V10359485, DMS8000 Connectivity Network guide.

More advanced technical issues are also discussed in the document no.

Also, you should have available the Composer project that includes the NK8000

network and all the NK82xx units.

Verifying the connection with NK82xx

The NK82xx download requires that the TCP/IP connection between the host PC and

the NK82xx is working properly.

In the Windows Command Prompt window, you can check easily this connection using

the Ping command:

 Ping n.n.n.n

where n.n.n.n is the IP address of the NK82xx unit, e.g. 168.123.8.76.

If the IP connection is good, the message text looks like the following example:

Checking IP connection

 Reply from n.n.n.n: bytes=… time … TTL=…

If the IP connection is not working for any reason, different messages may appear

(Request timed out, Destination net unreachable, etc.) In these cases, verify the

network settings and cabling and try again.

Downloading the NK82xx firmware

1. Start Composer and open the project that includes the control units.
