UCM/Cbus 5.235

[ident]

UCM/Cbus Firmware 5.235 is now available from https://www.cytech.biz/ucmcbus_firmware.html
This firmware upgrade is highly recommended because of the new features and bug fixes below.

Bugs Fixed

1. When sending group address to any application not just lighting,   counter is updated. eg if Trigger group address 1 command is sent to Cbus, Group Address 1 would be updated
   
2. When UCM/Cbus was RESET, only 8 Cbus group addresses were updated to their counters because of a status request
3. UCM/Cbus used to send Daylight Saving Time value of 0 when Daylight Saving time is ON and ignored Daylight Saving Time value from Cbus.
4. Various problems with Cbus Delays which require a Reset of UCM/Cbus to recover
   

New Features

1. Complies with Cbus Clocks and Timekeeping application timing and updating requirements. Responds to Refresh Request Date and Time message from Cbus. UCM/Cbus sends Daylight Saving Time value to Cbus as unknown  and processes DST value from Cbus.
2. Works with older SIM firmware 3 and 4 but not all features may be supported in older SIMs.
3. SIM V3 when Cbus is removed and re-connected can re-initialise after a command is sent to Cbus. Note: Cbus SIM V4 which supports the PUN (Power Up Notification) message recovers by itself when Cbus is reconnected.
4. UCM/CBUS suppports AUD01 plug in
5. UCM/Cbus can receive several messages from Comfort RS485 bus if busy.
6. Read SIM firmware version from SIM for Internnal use

Do you have any further information on how the AUD01 works with a populated CBUS UCM please ?

[ident]

The AUD01 is meant to be connectec to an amplifier and speaker. It allows keypad announcements to be made. It also allows a virtual keypad on a Ctouch to have voice like a real keypad. If the # key is programmed to be # rather than ENTER, then signing in will go into the voice menu. although the sound does not come from the Ctouch itself. The mic and speaker would have to be mounted elsewhere
For example you could talk to the visitor on the door station by the Ctouch

Hi, no physically - how would you populate the CBUS UCM with the AUD01 board, not what does it do.

Thanks

Sorry I think currently it cannot be one
The AUD sits on the same 10 pin connector that the Cbus sim does
A forthcoming version of the Cbus SIM will have extended connector above it which will allow the AUD to piggy back on it
so it would be a 3 level stack

Interestingly, I thought about this very same thing the other day in a slightly different scenario, when I removed an AUD01 board to add an ETH01 board instead...

I did notice that the headers were passed through the ETH01 board, and that - physically at least - I could have stacked the AUD01 board back on top... - I wondered if it would work (haven\'t had an opportunity to try), and allow me to continue to use both modules...

So, if the headers physically allow it, is it OK to stack multiple daughterboards onto a UCM? - will all such boards work OK?

Cheers.

The pass through pins  are designed to allow the AUD sub board to stack
ie you can stack a AUD01 on top of an Ethernet,  Cbus or other module to add voice and mic functions.

Putting a AUD on a cbus module will allow Ctouch to have a simulated keypad with voice

However you cannot stack a ETH on top of Cbus or RS232 or other module as there will be hardware conflicts\\
