Rs232 serial control for a projector

bagarrett74

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 shall work ones you setup the right com settings

if open your monitor // windows -> show monitor

you can double check the send values

Hi Brent,
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.)

You're sending the wrong characters stream. 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.

Also try to send data directly from a terminal window (CoolTerm is cool on the Mac). 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.

hi marc,

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

You're right.

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

hi bent,

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
