Outback Power Systems AXS Port SunSpec Modbus Interface Owners Manual - Manual (Page 5)

Introduction
Welcome to OutBack Power Systems
Thank you for purchasing the OutBack AXS Port. This product provides communication with other
OutBack devices. The device uses Ethernet access implemented by the Modbus Transmission Control
Protocol. The SunSpec protocol enables sending and receiving of remote commands, control settings,
and status information.
At this time, the AXS Port only provides support for OutBack charge controllers. Future firmware
revisions will allow support for other OutBack products.
NOTE: This product is for use instead of a system display such as the MATE3. OutBack does not
support the use of the AXS Port and a system display at the same time.
Audience
This manual is intended for use by anyone required to install and operate this equipment. Operators
must have software engineering knowledge and must be conversant in ANSI C programming and the
Modbus protocol. SunSpec client software is required for operation.
