Never have written a RS232 string. Have a Krell Showcase Processor with 232 in, and have the new rs232 adaptor for RTI T2. Need Help! Thanks, Radiorhea

Depends upon the code structure that the Krell wants to see. The adaptor simply transmits the ascii or hex codes that you tell it to.

The Krell manual should have the communication settings as well as the command protocol and string format.

Matt,
Don't count on it unless you have seen it.

The JVC DILA can be fully controlled by RS232, as can the old Vidikron projectors.

The Vidikron manual has one page with every RS232 code, written out just as you need to type it between an initial string and a carriage return.

A couple of years ago, after hassling JVC technical and my rep for almost three months, I was able to extract the RS232 info for the DILAs from them. It was a document of more than sixty pages that described in great detail how they constructed their RS232 codes, but it never gave any actual codes. You would have to read the thing, see if you understood it by trying it out, experiment...and nothing I could write to them or ask them about could get them to just send me a list of the damn codes.

Isn't that what I said? You will have to find the control protocol and communication format for the Krell device. The RTI will simply transmit these codes...

I have the data just need to know how to write the string. Krell provides everything data wise just not how to write the string. Thanks, Radiorhea

Radiorhea,

The RTI T2 software makes this easy:

1)Create a button

2)Edit a Macro on the new button.

3)From the "Command Type" box in the Macro Editor select RS232.

4)For BAUD rate choose 9600

5)For PARITY choose NONE

6)For DATA BITS choose 8

7)For STOP BITS choose 1

8)For IRF-6 port choose the port you are going to connect the RTI CM-232 module (and then connect to the Krell).

9)In the STRING section type in the RS-232 command from the Krell Developers manual for the Showcase. You can download that here:

[Link: krellonline.com]

For example, if you want the volume set to 100, type in 100MVLZ

If you want the input to go to CD, type in CDZ

10) Once your string is typed in, drag the ICON below the string to the macro list.

The T2 software is a wonderfully straightforward approach to programming one way RS-232 control of a component like the Krell.

Krell offer excellent automation support via an extensive list of RS232 codes for all of their processors. In addition, with more advanced automation systems like CoreAccess, Crestron and AMX, you can query the status of the unit and display current input, mode, level etc information on your touchscreen or use the information to create intelligent action on the part of the controller.

If you have any questions about programming this, give me a call.

Best Regards,

Thanks man! I'll try it tonight! My wife got a virus on her computer so that has been taking up alot of time. RadioRhea

Eric, have you ever done this with AMX Landmark? RadioRhea

All systems utilize RS-232 in the same way. The advantage of better automation systems than the RTI (including AMX Axcent and better) is that they can query the Krell for status and get information back which can be displayed on a screen for the end user.
