Networking and Addressing

The 24XStream 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 24XStream features a powerful set of

networking and addressing options allowing the functionalities 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 24XStream 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. The VID addressing ensures that modules with a given VID are immune

to either transmissions or receptions with 24XStream modules with a different VID in the same

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

Networks

Within each VID, there are seven available networks. Each network utilizes a different pseudo-

random hopping sequence to navigate through the shared hopping channels. In the event that two

modules from different networks collide on a channel, because they hop in a different sequence,

the two modules will jump to separate channels on the next hop. Using networks, multiple

module pairs can operate in the same vicinity with minimal interference from each other. The

network parameter is user settable using the “HP” command as described in the “24XStream
