The TEAC User Manual, page 27 lists three colour temperature settings, Low / Medium / High, ranging from 7180K to 10,180K and these are set from the OSD user menu by either the remote control or by front panel buttons.

Page 13 lists a fourth colour temperature setting, 6500 D, available by setting parameters via the RS 232 port.

Today I tried without success to communicate via the serial port.

I used a Windows 95 laptop, the HyperTerminal program, different comms cables (Null & straight-through) and a range of terminal emulations (VT 52, VT 100, Auto detect) and handshaking (none, hardware & X-On/X-Off).

The best result I got was to the command, AT to which I got the response OK.

I got no response to any further attempts, for example to read a parameter, such as "display the volume setting".

Anyone got this working?

All I want to do is to set the colour temp to 6500D...

Unfortunately I can't help, but I'm very interested in finding out!

What I do know is that the screen is made by Sampo. Some Sampo screens offer 6500D in their menus and also have a "semi hidden" colour temperature menu that allows for custom settings of RGB gain and bias. This was mentioned in a US review, but despite posting on AVS etc. no one has replied to tell me how to access it. Apparently it is described in the Sampo user manual - but that's not posted on their website yet.

I emailed Teac, but got no reply.

Well Chris, we are going to have to escalate this...

I've had a look at both the Taiwan and US Sampo sites and their PDF's. I think the specs on the link are not as good as the Teac - ours seems to be much better than the Gateway.

Here's another link, it's a 50" but the rest is similar. Note the reference to D65 the RGB bias/gain menu.

DONE: Got the RS232 interface to change settings in the panel today.

Can alter settings 'till the cows come in. Have set to D6500K on inputs for DVI & Component. Have yet to do extended testing to determine if settings are retained after power-off and through time.

All you new is the TEAC panel, an RS232 cable, software called "RS232 Hex Com Tool" from this vendor of hex programming software and a PC or laptop near the panel.

This result is at the end of a mission. TEAC Aust HQ read my email enquiry (I have the receipt but no answer). The local branch was sympathetic but had no knowledge (could not/would not give service menu details), SAMPO Americas ignored both requests, GATEWAY had no info and VIEWSONIC had a dowload which was their reprint of TEAC page 13. However, ViewSonic user guide (downloadable) showed their menu with the colour setting to D6500K as a selectable option. Encouraged afresh, I searched and found the software tool I needed. The download is free for evaluation & fully featured but shuts after 5 minutes of use and needs a restart. Buying the software is cheap enough for such a handy utility and removes reminders and the timed shutdown.

In summary, I deduce that "someone" overseas decided to eliminate an available setting in the user menu, way-back when. This means the panel will change to D6500K (option 03) under software control but the user menu text for colour setting cannot show the real setting.

Well, at least today we have V1.07 for our DVB 800 STBs.

ps This hex comm software can be used to program ANY device that takes data via RS-232 port

Well done!

Let me know how it goes. According to the reviews the D65 setting was pretty close on this panel.

Step by step instructions would be good too

Ok, will write a step-by-step doc, but not today - about to go away for 24 hours.

Perhaps a post tomorrow evening...

ChrisM,

Ok, here we go...

"How-to-do-it, Lite Version". You need a Windows computer, db9 to db9 cable and a TEAC 1060 panel.

a) Go to www.rs232pro.com web site link here and download the demo version of RS232 Hex Com Tool.

Install the downloaded program using windows > control panel > add remove programs. Let the program install and just click the default settings all the way. I loaded the program on to a Windows 95 laptop & there was a new entry under the Programs menu. I used a DB9 to DB9 cable (female - female) between my laptop COM port and the TEAC panel COM port.

The download is small enough to fit on a 1.44Mb floppy (remember these?). The installation is over & done in 2 shakes of a lamb's tail.

c) Start the program and read the Help files or just go to Jump In. There is enough info here to answer your questions / get yourself into trouble, depending on your experience / skills.


Jump In:
So, your computer & panel are connected via RS232 cable between the COM ports on each unit and both units are ON, Windows is booted & RS232 HEX COM Tool is running.

Now,

Setup the computer COM port parameters. 9600 is the speed, 8 bits, 1 stop, no parity. The port has to be set OPEN.

Set the Transmit ASCII / HEX and Receive ASCII / Hex (at left side of) data fields to each be Transmit Hex and Receive Hex. There are 2 unlabelled, weird looking buttons at the right side of the data fields. Just click and it toggles between ASCII / Hex. For those who do not know hexadecimal, the valid symbols are 0 to 9 inclusive and A to F inclusive.

Testing 1-2-3

Now, to ask the panel what is colour temperature setting. See page 13 of TEAC user manual for details of commands & valid data.

In the Transmit Hex data field type 80 98 Note: I pressed 80[spacebar]98
click on the red arrow symbol (hey, there is only one of them).

The panel will respond with one of the following: 00 or 01 or 02
00 is High temperature 10,180K
01 is Mid temperature 8,680K
02 is Lo temperature 7,180K

That is it - down to the pub......

------------------------------

Ok, let us select the DVI Input, change to 6500D and read the setting

in Transmit Hex field:

To select DVI input. Enter 91 07 click red arrow
To set temp 6500. Enter 98 03 click red arrow
checking:-
To read colour temp. Enter 80 98 click red arrow

response from TEAC is 03

-------------------------------
Well, that is the Lite version...

The RS232 Hex Com Tool program has more features than the above. It is possible to create programming scripts with the in-built editor to avoid all the typing, but I will leave you to explore these other features for yourself.

Please note, the demo version is fully featured but stops after 5 minutes. You can re-start the program as often as for 30 days. The purchased version is without nags or nuisances.

Tired & to bed.

Thanks for your efforts Robo, you're a legend.

I'll give it a go when I get a chance. Have you determined if the setting "sticks" after power down etc?

edit to correct typo. R.

Yes ChrisM, the setting does "stick". I set the temperature for all inputs to D6500 2 weeks ago and they are still set the same this morning.

Also, using the script feature of the program RS232 Hex Com Tool I wrote a looping sequence to change from HI to MID to LO to D6500 with a delay of 2 seconds between each change. The script cycles through the sequence 3 times and stops at ... D6500.

The effect is interesting (well, to me). HI has whites exhibiting a red shift and appear with a pink hue. The pink hue decreases with each lower setting and white is white at D6500. I guess we should expect that.

Fortunately, Channel 77 is static today for maintenance, showing just the channel $even red & white colours with text and so provided a stable image for comparisons.

I want to thank AlanH for his authorative guidance regarding D6500 and must say the correct setting makes a world of difference.
