Hi everyone,

I am trying to transfer data from a pulser/receiver device (http://www.tekxtreme.net/IMG_2958.jpg) to a computer through RS 232 interface.
I use the standard algorithm below to define a serial object as the following:

obj1 = instrfind('Type', 'serial', 'Port', 'COM1', 'Tag', '');

if isempty(obj1)
obj1 = serial('COM3');
else
fclose(obj1);
obj1 = obj1(1)
end

fopen(obj1);

data1 = query(obj1, '*IDN?');


However after the last command, i always receive the error "A timeout occurred before the Terminator was reached".

I have checked all the parameters ( Baud rate, stop bits, data bits..) whether they are consistent with those of the instrument. The only parameter which i have no idea about is "Terminator" property of the serial object. It is set to 'LF' by default but i don't know if i have to change this or not. I have read the manual of the pulser/receiver but could not find any information as to this parameter.

Can you please help me about this problem?
