     5The new chassis manager uses a completely new set of hardware compared to the older revisions. The design is based around the Lantronix XPort AR module, along with accompanying external hardware for interface to the node. The SDK for this device allows the implementation of custom code which is used to interface and understand CMC instructions.

    99 ==== Lantronix XPort AR ====
     10The Xport AR is an embedded device server, produced by Lantronix. It runs off of the [http://www.lantronix.com/device-networking/utilities-tools/evolution.html Evolution OS®], combined with the custom software written using the Xport AR SDK. The Xport AR acts as the 'brains' of the CM3, handling all the networking tasks, as well the link between the CMC instruction commands, and the physical interface to the node. It has the following basic features:
     11|| '''Architecture''' ||
     12||CPU              || Based on the DSTni-EX enhanced 16-bit, 120MHz x86 Architecture||
     13||Memory           || 1.25 MB RAM and 4 MB FLASH||
     14||Firmware         || upgradeable via FTP,TFTP, Serial Ports, Internal Web Server||
     15||Diagnostics      || Built in diagnostics and comprehensive statistics||
     16||'''Network Interface'''||
     17||Interface        || Ethernet 10Base-T or 100Base-TX (Auto-Sensing)||
     18||Connector        || RJ45||
     19||Layer 3 Protocols|| TCP, UDP, IP, ARP, ICMP, SSH, SSL, XML, HTTP, [[BR]] PPP, PAP, CHAP, DNS, SMTP, RSS, DHCP, BOOTP, AutoIP, SNMP, [[BR]] FTP, TFTP, Telnet, CGI ||
     20||'''Serial Interface''' ||
     21||Interface        || CMOS (Asynchronous, 5V Tolerant)||
     22||Data Rates       || 300 bps to 230,400 bps (selectable by 1bps increments)||
     23||Characters       || 7 or 8 data bits||
     24||Parity           || Odd, even, none||
     25||Stop Bits        || 1 or 2||
     26||Control Signals  || RTS, CTS, DSR, any PIO||
     27||Flow Control     || XON/XOFF, RTS/CTS, User Selectable Characters||
     28The GPIOs are used to control the solid state relays used to power the node on/off and reset the node, as well as monitor the 'hardware status', see the next section for details on this.
