Version 2.3.00 5 Theory of Networking Operations IP-Link 122X 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 122X should be configured, and what each nodes individual capabilities as well as constrains are.
Version 2.3.00 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 2.3.00 provides a single point of failure. Especially, the failure of the master node will result in complete system crash. To construct a star network using IP-Link 122X, only one IP-Link 122X module needs to be configured as a Master node. The remaining IP-Link 122X modules can be programmed as an End node. The most significant benefit of a star routing topology is its simplicity.
Version 2.3.00 routing pattern. This makes the messaging latency highly dependent on the instantaneous Link quality and difficult to predict. More importantly, a qualitative comparison of mesh algorithms is always a challenging task even for the most savvy network designer. Network designers usually deploy mesh for applications that require a highly reliable, highly available wireless infrastructure.
Version 2.3.00 6 Quick Steps in Establishing an IP-Link 122X Network In this chapter we provide some special notes on forming an IP-Link 122X 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. In this configuration, all nodes are viewed as equals, and each of them will be a “trustworthy” neighbor to any other nodes within its radio contact.

Version 2.3.00 7 IP-Link 122X 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 122X as a wireless network interface. Application developers usually use AT command set to query and set attributes on a standalone module.

Version 2.3.00 7.2 Binary Mode In Binary Mode, host applications use binary-formatted command and responses to command the local modules as well as communicate to remote nodes across the network. This highlights the key utility of Binary Mode operations compared to AT Mode: to communicate and command remote modules over the network formed by multiple IP-Link modules.

Version 2.3.00 Command Request (4-bit) b1000 Sequence Number (4-bit) When composing a Command Request Frame, user applications should supply the following information: • A four-bit, user-defined packet sequence number: this number will be echoed back in receiver’s Command Response Frame. • Destination node’s network address: Combined with the Packet Sequence Number, users can use these two numbers to uniquely match an incoming Response to a pending Command.

Version 2.3.00 7.4.3 7.4.3.1 Local awakened sleep Enter into sleep mode Awake the sleep mode from some local interrupts Command Code 0xB1 Description This command makes the module enter low-power sleep mode, if we want to awake the module from the sleep mode to normal work mode, can use some local operations. At present, can send a packet data from serial ports to awake the module. Command Parameters Awake origin 0: serial port awake 1~255:reserved Response Command Confirmation 7.4.3.
Version 2.3.00 8 Some additive commands and settings of module 8.1 The parity check of serial ports Users can set up the parity check function of serial ports by setting S103. When S103 is not 0, the serial ports work in the parity check corresponding mode. If S103=1,they work in odd mode; If S103=2, they work in even mode. 8.2 The flow control of serial ports In order to improve the corresponding quality of the module, we add the flow control in serial ports.
