      Good call Marc. Status response will be in
the first release. The command list looks like this at the moment (subject
to changes during development).
       
        
      B1R1On - Board one, relay one turn on
      B1R1Off - Board one, relay one turn off

      B1R2On - Board one, relay two turn on
      B1R2Off - Board one, relay two turn off
      etc. etc. up to eight
       
      The unit would return
      B1R1OnOK
      B1R1OffOK
      etc. etc. up to eight again
       
      Status response
      B1STATUS - send back the status of the
relays on board 1.
       
      
      The unit would return
      B1R1On,B1R2Off,B1R3On,B1R4Off, etc. etc.
These would be comma delimited.
       
      It is likely the command strings will be
case sensitive initially. I can make them so they don't care, anyone have
any views either way?
       
      Baud speed either 9600 or 19200.

            My two
pennies worth: status response. It would be nice if you could query the
state of the relays.

      Features : 
           
       
           
      Off r1
           
      On R2
           
      Turn R1 in 2Min for 1hour
           
      Flash R1 (interval)
           
      Group Relays together like 1,2,3 so they can
be toggled.
           
      Eg When issued with the command “turn On
R3” and then “turn On R2”  - R3 would turn off before R2 Came
on
           
       
           
      All this can be software controlled from the
plugin. 
           
      All I would need is the simple on/off
instructions to send to the serial port.
           
      What you think ?

      Sounds good to me. Can you start putting
together a wish list of features. I will be using a PIC micro controller
and a serial interface at up to 19200. I might even make the baud rate
selectable. Think about things like the commands you want to send e.g. R1
on, R1 off etc. You might want an acknowledgement as well. Lots of
fun.
           
       
           
      I am trying to keep it simple initially so
commands like R1 on for 1 hour then xyz will not be in the first
release.
           
       
           
      Thanks

      Hi Amar
           
           
       
           
           
      I have ordered the PCB's so assuming no
mistakes on my part boards will be available from about the 9th September.
I am away on hols for a little before that ;-))
           
           
       
           
           
      Details and pictures are on my site at
www.mollyology.com then projects and relay board. At the moment it is aimed
at HV and Comfort users but I will be putting together a small simple
serial interface for it. This latter bit will make it very similar to the
unit you have. You can be my beta tester if you like ;-))
           
           
       
           
           
      The relay board is opto isolated as well so
none of that nasty AC stuff going anywhere near your precious PC.

      When I was designing my relay board I
initially used reed relays which had some problems with things like
capacitive loads, AC etc. The relays on the SOM1 look very similar so you
may be experiencing similar problems. Check the relays are actually
switching off somehow with the speakers connected and showing the problems.
Alternatively use one of my boards <grin> which are rated up to 120v
AC and everything else you can think of.

      Loudspeakers use an AC signal, not DC. There
is no concept of a
           
           
      common ground, so you can't switch it that
way.
