UCM Firmware 5.228 can be downloaded from http://www.cytech.biz/ucm_firmware.html
Please note that products supplied by Distributors and Installers may not correspond to the latest firmware because of the supply chain. Firmware can be upgraded using a UCM
Version 5.228 (15 April 2011)
Bug Fixes- R! Command replies with OK so Comfigurator Execute Response will not have long delay. Fixed Bug from 5.146
- Fixed BUG seconds was not sent to Comfort when changed in UCM using DT command which includes seconds.
- UCM will report RIO zones (129 to 248) and respond to query of RIO zones
Improvements and New Features- Supports Tibbo EM500 (ETH02). SW8-F switch need not be shunted for EM500 in UCM/ETH2. However EM100 (ETH01) still requires SW8-F to be shunted
- Hardware Flow control is disabled. SW8-H shunt is ignored.
- UCM/Ethernet using EM100 can work in Bus Monitor - fixed Bug in previous firmware. Comfigurator 3.2.8 is needed.
- Transfer Data bytes increased from 56 to 64 bytes in one line of Rs485 message.
- DT report for date and Time added XX byte for DST byte 0 or 1
- When Upgrade Firmware fails during the intial UB command, addtional infomation appears for debugging
- RS485 Receive buffer queues mulitple incoming messages from Comfort so UCM will not miss any messages
- If checksum error in received message send NAK once instead of 2 times, and send checksum error immediately.
- If no rs485 comms from Comfort, - stop timer does not continue to count and trigger 256 seconds later
- Prevents stuck DLOAD, UPLOAD, COPY TEST switches on UCM from preventing UL and DL from working
- Increased Rs232 buffer size from 500 to 1000 bytes
- added f?00 command to request 64 user flags in a single command. Used by Wizcomfort to query flags.
- Prevent RS485 reply from corrupting the communication bus if the reply is delayed for any reason by an internal process. The Rs485 reply will be transmitted at the next poll.
