Chapter 11 Simple Serial Interface (SSI)

Introduction

MiniScan scanners communicate with a host device using Symbol's Simple Serial Interface (SSI). This interface is
only available on Symbol MSXX04 models.

The Simple Serial Interface (SSI) Programmer’s Guide (p/n 72-40451-xx) and Simple Serial Interface (SSI)
Developer’s Guide (
p/n 72-50705-xx) provide general information on SSI, include information on the decoder’s
hardware signals, and describe the commands. The following SSI information is specific to the MiniScan scanner.

Revision String

When the decoder sends the REPLY_REVISION message, the revision string is in the following format:

S/W_REVISION BOARD_TYPE ENGINE_CODE PGM_CHKSUM

where:

S/W_REVISION is the release name of the software

BOARD_TYPE is N for non-flash decoder board, F for flash

ENGINE_CODE indicates the type of scanner paired with the decoder

PGM_CHKSUM is the two-byte checksum of the program code.

NOTE

MiniScan scanners only support Multipacketing Option 1. See the SSI Programmer’s Guide for more
information.
