Communicating with the Module
12.1
Host Communication (SkyeTek Protocol v3)
The SkyeModule Nova operates under control of a host according to SkyeTek Protocol v3. The basic
command and response formats are illustrated for your reference in the following two sections 12.2 and
12.3. The best way to get started creating and understanding commands is to follow the application
notes below while using the Protocol Builder in SkyeWare v4:
Nova Basic Tag Commands
–
Guides you through the select tag, read tag and write tag commands.
SkyeTek Protocol v3 Reader Commands
–
Explains how to read and write system parameters.
For more feature specific commands, use the tag specific application notes listed in the Additional
Reading section 1.3.
For a quick reference on the protocol if you already know the command you want to use, see the
SkyeTek
Protocol v3 Reference Guide
. This provides detailed information on each command structure, error
codes, and tags types. Be warned that this document is very lengthy as it details every command
available for every SkyeTek module.
