Hi All,

I have been having some problems with controlling an Aquavision 26" via RS232 with RTI, and was hoping someone might be able to help.

First off, I know the commands I am trying to send are correct, and know they are getting to the TV in the en-suite.

When connecting my laptop to the TV using TerraTerm I can turn the tv on and off with commands, POWR00 & POWR01.

When connecting my laptop at the TV I read the correct commands coming from my RTI XP-8.

Yet put the two together and nothing.

So I connected my laptop to the TV and tried again with TerraTerm and everything works fine. So I decided to use some of my other control software to check they all work. They do not. I tried Commaster, 232Anaylzer and Docklight, none work. Whenever I send a code I get a partial echo of what I sent before, "PW1" PR0" etc.

I tried putting in a character delay, nothing. I know TerraTerm includes a null command at the end, which I put in and still nothing.

I then realised I had a 40" AquaVision in stock and tried that on site. Everything works fine ! So I got a replacement believing the unit I had was faulty, and still the same bloody problem with the new unit.

I am really really baffled at the moment, I can't believe I have two faulty units yet the 40" works ? All my other equipment is being controlled fine via RS232 on this site, I tried a second RTI XP-8 and still no luck. Aquavision are not really help at all and my RTI help has reached an end point as when I tried with the 40" everything worked so we all believed a faulty TV.

Please oh please someone shed some light on this. Why does TerraTerm control the TV but no other programs can?

Any absolutely ANY ideas welcome here.

Don't know if this helps, but just looked in an AMX module I wrote for an Aquavision.
SEND_STRING DVaQUA,"$0D"
WAIT 10 SEND_STRING DVaQUA,"'POWR01',$0D,$0A"
Similar for power off. In case this doesn't make sense, it sends a carriage return, waits one second, then sends 'POWR01' carriage return, line feed.
Other commands do not seem to need the preceeding carriage return.

I cannot remember doing the programming, but guess it may be needed to clear a buffer or something like this.

Hope it helps.

Hi Henry,

Thanks for getting back to this problem of mine,

I'm a little confused on your commands, is the code you sent,

"$0D" for power on ? I don't know about AMX and if what you have written is standard code or something designed for AMX modules.

If you could clarify where the code actually starts and ends i would love to try it as I am about to throw this TV out the window.

Many many thanks for your reply.

Sam.

Hey guys,
I know this thread is almost a year old now, but given there was never a final solution to this I thought I'd let you know what I've dsicovered:

I had exactly the same problem, RS232 to Aquavision works fine from my Laptop in Hyperterminal or docklight, but sending the same string from Control4 doesn't work at all. I can confirm the string is outputting correctly from Control4 by using Docklight aswell.

After hounding Aquavision for an answer we finally got them to suggested that a 200ms delay between each ASCII character will fix the problem. It seems the serial hardware in the TV has a very poor buffering capability, and so the string output from the control system was simply arriving too quickly for the TV to process. That's why when typing the characters on a keyboard it worked fine because of the inherent delay between characters when you type.

Hope this helps someone out there. I spent two days trying to solve this one.

I know this is a bit of a bump, but I'm so close to figuring this out thanks to this thread!!

I just need to know how to make that delay between characters in control4 driver wizard!!

The documentation says about using # followed by the number of milliseconds, but this doesn't seem to work inside the "", as far as i can tell iv tried every combination of codes and # that i can think of, anyone got this working?

Thanks for anything you give me that might help!

Andrew

I know this is old but I am a newbie and have a 40” Aquavision TV which is responding only to the On/Off functions on my remote. It comes on and is stuck on a channel with subtitles and appears to be muted. It had been working tempramentally from the start... Any pointers on this site as to how I can rectify this. I did notice before that pressing buttons too quickly upon start up would interfere or sometimes stall the start up which only rectified itself after turning the power off and on... not so now of course... any help to be had here???? Thanx in advance.

First of all, you give us no information with which to answer.

1. What brand and model of remote are you attempting to use/program.
2. Model# of TV would be helpful.
3. From what I have found in this brief thread, it appears a delay should be instituted between character transmission of at least 200ms. In the control4 world, the delay should not have "" around it while building a one way driver. The ocotothorpe delay is part of the proxy. The code you wish to send would look like $0D #200 $0A or "INPUTSELECT" #200 "HDMI1".
No, it doesn't come preprogrammed.

When you use hyperterminal and press "enter" you are sending a and .

these are 0D and 0A.

Make sure you are adding this to your control system. They all do it differently. Look for things like \r \l $0D \x0D etc.
