ASCII string

Trying to send RS232 sting from PACA.
9600 Baud, 8 Data Bits, 1 Stop Bit, No Parity
Initialisation
OpenSerial(2, 2, 9600, 8, 1, 0, 1);
Code
once (GetLightingState("70_Master door close") = ON) then
begin
WriteSerial(2, '0101U');
end;
I can send this code from Ness M1 without any problems.
What am I doing wrong here?
Thanks
George

 

Hi Nick,
What I'm trying to send is 01 controller address, 01 motor address and U up.
Thanks

 

Do you need "carriage return" and/or "new line", something like #13#10?

 

I’ve tried 0101U^M and it doesn’t work.
Thanks

 

Hi Nick,
Thanks for that but still unable to control the motor.
Will have a look into wiring again.
Thanks

 

Have you connected a 24VAC supply to the PAC?

Also some device need either a LF or both CR LF so try

WriteSerial(2, '0101U'#10);

and

WriteSerial(2, '0101U'#13#10);

 

Hey, Not wanting to be too 'suck eggy' but just because it has caught me out before, but you do have your cable plugged into the RS232 port 2 as per your initialisation?


Just noticed.. you have said you wanted no Parity, but your code is written for Odd by the looks?
I think you may want:
OpenSerial(2, 2, 9600, 8, 1, 0, 0);

From the help file:
For use with the Pascal Automation Controller, there are the following limitations :
·SerialPortIndex is the User Port number (1 or 2)
·COMPortNo is the User Port number (1 or 2)
·BaudRate is limited to 600, 1200, 2400, 4800, 9600, 19200, 38400
·DataBits is limited to 7 or 8
·StopBits is limited to 1 (= one stop bit) or 2 (= two stop bits)
·FlowControl is not used
·Parity options are limited to 0 (= none), 1 (= odd) or 2 (= even)

To open serial port number 1, with COM Port 4, 9600 baud, 8 data bits, 1 stop bit, no flow control, no parity :
OpenSerial(1, 4, 9600, 8, 1, 0, 0);
OR
OpenSerial(1, 4, 9600, 8, scOneStopBit, scNoFlowControl, scNoParity);

 

Yes, my mistake with initialisation as it should be no Parity.
I've changed it and...........no luck but then,
Changed all to port 1 and its working.
Just wondering if its possible that port 2 on PACA is fried or am I making a mistake
when cable plugged in PACA port 2 and initialisation is OpenSerial(2,2)?

OpenSerial(1, 1, 4800, 8, 1, 0, 1);
OpenSerial(2, 2, 9600, 8, 1, 0, 0);

once (GetLightingState("70_Master door close") = ON) then
begin
WriteSerial(2, '0101U'#10);
end;
once (GetLightingState("72_Master door open") = ON) then
begin
WriteSerial(2, '0101D'#13#10);
end;
once (GetLightingState("71_Master door stop") = ON) then
begin
WriteSerial(2, '0101S');
end;

Thanks
George

 

Faulty second serial port on PACA.
Does anyone know if its possible to repair?
Don't want to throw out almost new module.
Thanks

 

Well, you should be able to send back on warranty if new? If not, if you are ok with soldering and in particular surface mount you should be able to replace the RS232 transceiver. It will most likely be the transceiver, may have had a static shock or ect or just DOA.
