24 Introducing HSL

1.4.5 Networking Topology

Base on the RS-422/RS-485 architecture, a variety of topologies

are available for an HSL circuit, including serial, multi-drop, star,

etc. The following sections illustrate some applicable network

topologies for your reference.

Serial wiring

All slave I/O modules are connected using a twin-head

100BaseTX cables.

Figure 1-13: HSL networking topology – Serial

Since two notches of any slave I/O module’s termination board

are short circuit, this type of wiring provides the most conve-

nient and intuitive way to form a HSL network. The longest wir-

ing length is 200 m with under 6 Mbps.
