1 Introduction
1.1 Purpose
This document describes Otis’ application of the Remote Serial Link (RSL) within the Elevator system. This
document should serve as a reference for creating modules that communicate using the RSL protocol. This
document is meant to be referenced by multiple Module SIDs and does not intend to capture Module specific
information.
Any Module or Message specific information found in this document are examples and should not be construed
as a definition of a standard for a Module or Message.
This document will be updated when the RSL protocol standard or Otis’ application of RSL is amended,
following approval by the Interface Change Control Board.
1.2 Overview
This document has been divided into the following sections and subsections. The combined information in
these sections provides a complete description of Otis’ application of the RSL protocol.
! Protocol Description
o The protocol description is an introduction to the Otis RSL Protocol and its expected functionality
in relation to commercial protocol standards, primarily the 7-layer OSI standard.
! Functional Allocation
o This section specifies the functions that are supported by the interface. The functions in this
section support or interact with functionality in other modules. The interface requirements are
generally driven by the cross-module functional interactions.
! Appendix
o List of Acronyms and Definitions.
o List of references that may be useful in understanding this document or its history.
