and Network Expansion Using Physical Layer Repeaters
(Repeaters simplified for illustration purposes)
Audience
The LONWORKS FTT-10A Free Topology Transceiver User’s Guide provides
specifications and user instructions for FTT-10A transceiver customers and
users of control modules, network interfaces, and routers based on the FTT-10A
transceiver.
Content
This manual provides detailed technical specifications on the electrical and
mechanical interfaces and operating environment characteristics for the
transceiver module.
This document also provides guidelines for migrating applications from a
LonBuilder Developer’s Workbench Emulator or NodeBuilder Development Tool
to an FTT-10A-based node. Complete references and vendor sources are
included to simplify the task of integrating the transceiver with application
electronics.
This document has a list of references in Chapter 7. Whenever a reference
document is addressed, a superscript number corresponding to the reference has
been placed in the text, e.g., Standler
10
. Whenever a specific chapter or section
within a reference has been referred to, the reference is enclosed in brackets and
the chapter is addressed by number, e.g., Reference [1], Chapter 7.
