serial protocol problems - help needed

February 2007 in NetLinx Studio

Hi all

I am working with ARCAM tuner with rs232 protocol.

I am trying to send this command:

Quote from the protocol:

Select a preset radio station.
Example
Command/response sequence to select preset 12:
COMMAND: 0x21 0x13 0x01 0x0C 0x0D
RESPONSE: 0x21 0x13 0x01 0x01 0x0C 0x0D

When I am sending this command from the telnet for preset 2 like this:

send_string 5001:4:1,$21$13$01$02$0D

its working.
from my program - nothing...I can see the netlinx port number 4 tx led is working but the tuner is not responding.

looking at the notification windows shows the same command - (from some reason it shows the $21 character '!' instead of value)

Same happen to me in other devices too of Kramer. there must be something I am doing wrong here....

I tried everything I know, several string formats, I even made a button event to set the baud rate just to make sure its set.

BTW this device is not sending ONLINE event when its starts, only string event.

Attached are my program and notification window capture.

Thanks for any help

You are not sending HEX values, you are sending the ASCII equivalents.

For example:

Preset01 = '$21$13$01$01$0D'

The single quotes make it ASCII. I'm not certain how to do this in the DEFINE_CONSTANTS section; I would do it in DEFINE_VARIABLES as:

CONSTANT CHAR Preset01[] = {$21,$13,$01,$01,$0D}

This will store each string by the HEX value, which I am presuming your protocol requires. If it really does what the ASCII encoding of the HEX, well, never mind .

OUCH!!!

I was debugging all day cause I send wrong values???

I suspect the values, but I tried different version with no sucess, but not inside variables.

Why does the notification windows shows the same?

Thanks a lot, I will check it asap on the morning

it's strange that the notification window showed '!' instead of $21

It does that when it's sending out "real" hex strings, but since you were sending out ASCII strings i'm really curious what's happening.
Did you get the '!' when sending from Terminal window or from your program?

The notifications window will always show ASCII characters when it can and if it's unprintable then it will show the 2 digit hex code.

It would be a nice option to have it display all hex if desired. Feature request?...

When you're sending Hex: Power_button[] = { $21$00$01$01$0D }

Just thought I'd give you another idea.
Try this in your code, it is much easier to read and faster to code$$$

DEFINE_EVENT

BUTTON_EVENT[dvTPStudyRoom, nTPTunerBtns]
{
  PUSH:
  {
    STACK_VAR INTEGER nBtnIndex
    nBtnIndex = GET_LAST(nTPTunerBtns)

    if(nBtnIndex == 1)
      send_string dvARCAM, "$21$00$01$, nBtnIndex  ,$0D"    //power command
    else
      send_string dvARCAM, "$21$13$01$, (nBtnIndex-1)  ,$0D"    //all others
  }
}

The port your Arcam is on may never get set to the correct baud rate. Move your "SET BAUD" commands OUT of define_start and put them in DATA_EVENT -> ONLINE: handlers. You are more than likely asking that com port to go to 19.2k before it has come online, so when it actually does appear, it stays at whatever it was at previously - probably 9600.

From the telnet ( you can see it in the attached picture at the begining of the thread)

You can see that I am listening to the online event too, and its never gets there.
when the arcam device up its sends STRING data event and not online...

is this is normal for devices or am I doing somthing wrong?

Hardware devices built into the controller chassis (serial, IR, relay, and IO ports) generate an ONLINE event once they start talking to the master, and not again unless the chassis is rebooted or the system gets restarted. In most cases, it happens just after DEFINE_START runs. Unless you connect to the master very quickly after a restart, you aren't likely to see these ONLINE events happen, they are already done.

I only saw the SET_BAUD commands you have in DEFINE_START - not the ones in the module under DATA_EVENT ONLINE:.

Since that online event happens shortly after the processor reboots, you're probably just not reconnecting to the master in time to see the "ARCAM ONLINE" message...
