Version 1.1.01 5 Theory of Networking Operations IP-Link 1223 can be configured in a number of network topologies to meet different application needs. It allows the users to design a network that best matches their installation conditions and applications’ needs. To design a network, it is empirical to understand how each individual IP-Link 1223 should be configured, and what each nodes individual capabilities as well as constrains are.
Version 1.1.01 On the other hand, a routing topology is a routing pattern over a multi-hop network. It describes an imaginary wiring diagram, weaving together all network nodes, allowing any arbitrary point to initiate a message (either unicast or multicast) to any fellow node in the network. A routing topology is constrained by the underlying connectivity topology.
Version 1.1.01 as a Master node. The remaining IP-Link 1223 modules can be programmed as an End node. The most significant benefit of a star routing topology is its simplicity. The simplicity translates into very low-overhead protocol implementation, much lower overall device cost, very low-overhead routing information, and ease of administration. The central Master node can also assume many administrative roles such as certificate authority for authentication, or remote management gateway.
Version 1.1.01 Network designers usually deploy mesh for applications that require a highly reliable, highly available wireless infrastructure. Mesh networks should also be considered as a means to reduce initial network setup cost and post-installation maintenance needs by leveraging the self-configuring capabilities embedded inside IP-Link 1223 modules. 5.
Version 1.1.01 6 Quick Steps in Establishing an IP-Link 1223 Network （ In this chapter we provide some special notes on forming an IP-Link 1223 network The ） establishment of Mesh network please re. 6.1 and 6.2 . 6.1 Special Note: Establishing a Full Mesh Network A full ad hoc mesh network is appealing to many users because of its ease of configuration.

Version 1.1.01 7 IP-Link 1223 Command Set Helicomm IP-Link supports two categories of external command sets. One is the familiar AT command set that is similar to those supported by Hayes-compatible modems. The second category of commands consists of binary instructions that enable a host processor to use IP-Link 1223 as a wireless network interface. Application developers usually use AT command set to query and set attributes on a standalone module.

Version 1.1.01 Response Frame to take further actions. Some configuration records and sensor information natively supported by IP-Link1223 can also be retrieved using Command Request and Command Response. These commands are built-in to IP-Link 1223, and these Commands cannot be extended or modified by the users. On the other hand, host applications use Data Request and Acknowledgement Frames to exchange user-specific data.
Version 1.1.01 Bit 3,2,1,0: Packet Sequence Number, modulo 16. NOTE: This sequence number is specifically designed for user applications, the nearby packets must have different sequence numbers, for example, the sequence numbers IP-Link 1223's firmware maintains separate sequence change circularly from 0 to 15 numbers for data packets. They are transparent to Binary Mode users. 。 7.2.1.
