PmP Firmware release notes – version 5.xxVersion 5.xx runs only in the newer radio models (AR-9010E, AR-9027E, AR-24010E, AR-24027E, AR-24110E). This version is now outdated. Whenever possible use the latest version of the firmware.
Version: 5.82 Date: August 27, 2010
New FeaturesSupports blocking the illegal channels in the middle of the 900 MHz band in Brazil and Australia. Added encryption using DES-56 (standard), and Triple-DES, AES-128, AES-256 (optional).
Problems FixedFixed some race conditions that could result in some packet losses under heavy loads.
Version: 5.85 Date: October 4, 2010
New FeaturesAdded monitoring of the tx power level and a warning (in the “show” command) if the measured level is significantely below the configured value.
Problems FixedImproved calculation of link distances. Improved handling of VLAN encapsulated packets.
Version: 5.87 Date: December 30, 2010
New Features“>single-node timeout” feature can now be disabled by giving it a timeout value of zero
Problems Fixed:Corrected display of UDP information in DISPLAY-CONFIG Improved performance on links with low RF signal levels. Fixed memory leak in DOWNLOAD and SET-DEFAULT-PROGRAM commands. Resolved problems in ECONSOLE retransmission code that could cause hung sessions. Correct link timing problems that could cause reboots in model AR-24110. A node with 20 ms cycle period could reboot when synchronizing to a 40 ms source.
Version: 5.88 Date: January 19, 2011
New Features“>monitor-link 0” can now be used to monitor all direct links simultaneously.
Problems Fixed:Roaming: Under some conditions the remote broadcast of a proxy packet on behalf of the host stations (to tell network their new position) was not being issued. This may cause longer roam transition times. Improved transition time when current hub drops suddenly. Corrected warning at a remote radio that rx channel was being set while transmitting. Heartbeat synchronization: Better rejection of hearbeat pkts that got delayed in external switches. With a cycle of 20 ms heartbeat packets were being discarded unnecessarily.
Version: 5.89 Date: Mar 23, 2011
New FeaturesSpeeded up code downloads when using Econ. While running “monitor-link” you can now press 0 to restart the statisitics. Improved power management for remote/leaf nodes: If a remote or leaf node has a link up but there is little or no traffic, the power consumption is now around 1.8 W and goes up as the traffic increases. Prior to this revision, the power consumption with no traffic was over 3.0 W. Note that while the radio does NOT have a link its power consumption did not improve and is around 3.0 W.
Problems Fixed:RF receiver is now turned OFF when not needed – reduces susceptability to interference from transmissions of radios nearby on the same or adjacent channels. Heartbeat synchronization: In a two hub system, if one hub was rebooted, could result in the two hubs not negotating the master correctly and cycles not being synchronized.
Known Problems:If a “branch” node powers up and does not find its parent, if the parent shows up later, the node does not attach to it until it is rebooted. When the Ethernet is running at half-duplex, the radio incorrectly logs errors for every packet sent out, filling the event log quickly.
Version: 5.90 Date: Jul 7, 2011
New FeaturesThis version can now also run on the “Classic” radio model AR-24027. This allows that model to be over-the-air compatible with the AR-24027E. For full compatibility all units in the same network need to be running this version or later.
Problems Fixed:Branch node will now find a parent, even if it was not present on power up (problem introduced in version 5.89) Ethernet in half-duplex now does not trigger logging events incorrectly (problem introduced in version 5.89). The AR24110E could exhibit packet drops at certain distances even with a clear signal. This has now been fixed.
Known Problems:Radio used to snoop on NTP packets and set date and time automatically. That feature is not working in this version (corrected in 5.91)
Version: 5.91 Date: Sep 27, 2011
Problems Fixed:Radio now snoops on NTP packets and sets date and time automatically if they are present (feature got broken in version 5.90). For the 900 MHz models the maximum allowed transmit power is now 26 dBm. With previous max of 27 dBm, the transmitter power amplifier could get damaged when transmitting into a reactive load.
