Lexicon serial problems

adys

Hi guys

I am working with MC-8 ver 2 .
The AMX module is working only with MC-8 ver 1...

The program that came with the module sent properly only few command.

I am trying to work with the serial command with no success..I am sending command like this:

Set Volume - SEND_STRING dvLexMC8, "'$F1,$04,$40,$01,$01,$F2'"

its not working...

I am also trying to understand how to change input and the document is not clear to me. every company has it logic, and this one is so not clear I don't understand what they want...

Ok, we found a solution - to use the "Ir Codes" commads via serial commands. nice solution.


We have a strange problem:

DATA_EVENT[dvLexMC8]
{

ONLINE:
{
SEND_COMMAND DATA.DEVICE,'SET BAUD 19200,O,8,1'
}
STRING:
{

local_var char cLCD_DATA[64];
cLCD_DATA= DATA.TEXT

SEND_STRING dvDebug, "'lexicon string'"
SEND_STRING dvDebug, DATA.TEXT

} // END OF - string event
} // END OF - data event



The device is not sending strings to the data event...

but If we connecting it with a serial cable to the terminal program - we can see that its sending string on the serial port.

the code is the same for a lot of other serial devices.

Any idea how to start solving this?

thanks

SEND_STRING dvDebug, "'lexicon string'"
SEND_STRING dvDebug, DATA.TEXT

SEND_STRING dvDebug, "DATA.TEXT"

Did you remember the quotes in your actual code?

adys

yes..

The code don't reach there at all, not even with the a debugger.

Netlinx studio notifications window also don't work.

Only when connecting with a cable via terminal its sending some strange characters...

I can understand that maybe there is some porblems in the code, but why the notifications window don't show the coming strings?

Problems Solved

I changed the line

SEND_COMMAND dvLexMC8, 'SET BAUD 19200,O,8,1'

to be

SEND_COMMAND dvLexMC8, 'SET BAUD 19200,O,8,1 485 Disable'

and now it working like it should...

Why is that?

I messed with it 2 days just to find out this 485 disable .. this is not written anywhere

Should both work, the '485 DISABLE' or *ENABLE*is optional (but must be written uppercase). For RS232 control (pins 2,3,5), it also doesn't matter if 485 mode is enabled or disabled (it's just a different handling of the data sent and received on pins 1,4,6,9). Maybe it's some kind of side effect if a full patched com cable is used and 485 mode was ON.
