Networking and Addressing

The 9XStream modules utilize three levels of addressing to communicate

between modules. This networking hierarchy is depicted in Figure 8 below.

Only modules with the matching addresses are able to communicate.

The three

methods of addressing are: Vendor Identification number, Networks, and

Module Addresses.

Figure 8 – Layout of a typical network configuration. The 9XStream

features a powerful set of networking and addressing options allowing the

functionality of complex networking systems.

Vendor Identification Number (VID)

For network security, a unique Vendor Identification Number (VID) can be

requested. The VID is programmed into the 9XStream module at the factory and

is stored in permanent memory. This number can only be changed at the factory.

Only modules with matching VID numbers can communicate together. VID

addressing ensures that modules with a given VID are immune to either

transmissions or receptions with 9XStream modules of a different VID in the

same vicinity. To request a unique VID number, contact MaxStream to obtain a

VID Request Form.
