4.1. Addressing

XCite radio modems utilize three layers of addressing to communicate between radio modems. 
The network layers are depicted below. Only radio modems with the matching addresses are able 
to communicate. The main layers of XCite Networking and Addressing are:

• Vendor Identification Number (ATID)
• Channel  (ATHP)
• Destination Address (ATDT)

Each network layer provides a separate layer of filtration. The Vendor Identification Number (VID) 
provides the first layer of filtration through the ID (Modem ID) Parameter. If the incoming RF data 
carries a matching VID number, the data continues through to the subsequent Channel and Desti-
nation Address layers. The Destination Address is the last network layer and provides the most 
granular form of filtration. If at any point during the incoming RF data flow the numbers in ques-
tion do not match, the data is discarded.

XCite Modules and RF Modems are built around a peer-to-peer protocol that inherently supports a 
multidrop type network (similar to RS-485). In their default state, any XCite radio modem will 
communicate with any other XCite radio modem in its default state.

4.1.1. Vendor Identification Number (ATID)

The bottom half of the ID (Vendor Identification Number) Parameter range is user-settable. The 
upper half of the range is factory-set and read-only. The value of the ID Command is called the 
Vendor Identification Number (VID). A unique VID is available upon special request. The VID is 
programmed to the XCite Module at the factory and is stored in the modem's permanent memory. 
Only modems with matching VIDs can communicate with each other.

VID addressing ensures that radio modems ignore transmissions and receptions of XCite Radio 
Modems having a different VID in the same vicinity. To request a unique VID, contact MaxStream 
to obtain the VID Request Form.
