<![CDATA[Rs232 serial control for a projector]]>Hello,
I am trying to control the shutter of an X85 Eiki projector through Isadora's serial control. I am not having much luck. I am able to control the shutter through Dataton's Watchout. The code I use for that is C0D$0D. That will close the shutter. I installed a Star Tech serial pcie card in the Mac computer and it shows up as working in the Systems menu. I believe my serial cable is correct because it works with the Watchout system. Any thoughts.
Thanks,
Brent

it's not me 
mark implemented the lovely feature to rename the actors
so it is just a "trigger text" actor having the appropriate name 
and giving the string (input) to the send serial actor
if you are unsure what actor it is you can use the actor help (right mouse click on the actor)
to identify them
great it worked out
best clemens

Your .izz file worked. I was curious how you made the actors for that. I searched mute and unmute in the actors and didn't find an actor titled mute and unmute. Did you build that yourself somehow and if so would you explain that to me.
Thanks,
Brent

reading page 6 of the wiki specs
suggests that the whole part before the carriage return is a ascii string
as the 0x0D is the sign that decoding can start
so it will be 
"C" 0D 0D to mute
"C0D" 0D to mute
anyway i think without a projector it is hard to verify
and we have to wait for brent
what is working

The projector must reply 6[cr] on each valid command or ?[cr] on unknown commands according to the tech docs (chapter 6).
And if it still doesn't work, swap pins 2 and 3 on one side of the cable.

I don't have a beamer in hands to test, but I will try the following code from Send Serial Data actor:

"C" 0D 0D to mute
"C" 0E 0D to unmute
By default, the serial actor send hex. Hex are often noted 0x## or $## in tech documentations, but you don't have to send these 0x or $. By putting the C in brackets, you tell Izzy to send an ASCII character. If you monitor your output with a terminal, you will get in hex 43 0D 0D (43 is the hex for C) or 67 13 13 in decimal.
Also double check the transfert speed. Eiki X85 default is 19'200bds 8 bits no parity no handshake.

I am not serial data expert... but this seems to output the required data string in my monitor window (Sorry I don't have my dongle license with me tonight, so uploaded a screen grab instead.)
