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.
Introduction Accessories ¾ The AXS Port can use a Type 2 microSD card for logging operational status information about the system. A 2 GB microSD card is included. The SD card is also required for performing firmware updates. ¾ The AXS Port can be equipped with a clip for mounting on a DIN rail. This clip is included. ¾ The AXS Port can be equipped with an additional temperature sensor to supplement the battery sensor used by other OutBack devices. Ambient temperature of a room, PV array, etc.
Operation Installation Instructions Mounting To mount the AXS Port directly on a wall or flat surface: 1. Insert two screws (appropriate for the surface) into the mounting holes at the top and bottom of the device. The holes will accept up to a #6 screw. 2. Tighten securely. Figure 2 Wall Mount To mount the AXS Port on a DIN rail: 1. Orient the AXS Port upright so that the DIN rail clip is next to the rail. 2. Next, place the clip against the DIN rail. Hook the upper edge of the clip over the DIN rail. 3.
Operation Cabling If a single OutBack product is used, it can connect directly to the AXS Port. If multiple OutBack products are networked on an OutBack HUB, the HUB can connect to the AXS Port. - OutBack Device Cable Network Cable HUB/Device Port Network Port 1. Connect the CAT5 cable from the OutBack device to the connection labeled “HUB Port” on the AXS Port. The Power LED will illuminate. (See Figure 6.) 2. Connect the network cable to the connection labeled “Network Port” on the AXS Port. 3.
Operation LED Indicators ¾ OutBack Device Communications LED: Blinks when data is being transmitted or received from OutBack devices on this port. HUB/Device Port Modbus Activity LED (green) ¾ Modbus Activity LED: Blinks when Modbus registers are being written or read. ¾ Ethernet Activity LED: Illuminates when the AXS Port is transmitting or receiving Ethernet packets. ¾ Ethernet Link LED: Illuminates when the AXS Port has established an Ethernet link with a network, or with the Internet.
Operation SunSpec Blocks The AXS Port uses the SunSpec protocol to assemble blocks of data on each connected product. The SunSpec client software can read or write to each field in a data block on the AXS Port. The fields are used for remote commands, control settings, or status information on the OutBack product. A user with SunSpec client software can use the following tables to interpret these blocks. Samples of the SunSpec client software are available at www.outbackpower.com.

Operation To update the firmware using an FTP site and the SD Card: 1. Connect to the AXS Port using the FTP site. 2. Copy the update file from the OutBack website to the UPDATEFW directory on the microSD card. NOTE: It may be necessary to create this directory on the SD card first, using the FTP client. 3. Once the update file is copied, disconnect the FTP client from the AXS Port. 4.
