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.
