I am trying to configure a LSID 0704 RFID reader without success.
Tried different configuration of baud rate but data output is always bogus character.

Connector is RS232 with Green White Brown wire connected.

Thanks for your help.

I think Guest_SHNOWLERS means that at step 1.2, he gets the "Data line not plugged in or the device is not open" message.  @Guest_SHNOWLERS  Is that correct? @Young What does he have to do in this situation?

Any news about this request? Our customer sent us their LSID_0704 and we
can't get it to work either. We've tried using the demo program (download
,
instructions
; breaks
at step 1.2) and even tried using our own program implementing the protocol
(download , procotol
; data is
sent, nothing is received).

We've tried connected directly with RS-232. We've tried using an RS-485
adapter (see picture). We've tried connecting the RXD and TXD to an FTDI
chip (TTL UART to USB). Nothing works.

When we connect the device to power, the device does beep, and approaching
a RFID card in its range does make it beep some more, but just can't seem
to communicate with it.

Please let us know what we can do next.

It sounds like the reader can work, but it can't communicate with your PC.

Could you post a picture of your wire connection here?

Does Dropbox work for you?  The links are public.

 

How about this?

If not, I'm not sure what I'm supposed to do because I can't find an upload button for this forum.  Do you have access to the original email you received on Monday?

I viewed the pictures. You use RS485 converter? I think it is not need.

 

The reader is RS232 interface. I used an USB to RS232 Converter cable:

Plug the cable to PC, then you can find a COM port in PC Device Manager:
 

0702 7

 

Connect the reader's RS232 interface to USB to RS232 Converter cable:

Then plug the 12V DC power.

Next is demo program operation:

 

1.  Download the demo program: https://s3.amazonaws.com/linksprite/RFID/integrated+reader/demo+program+for+LinkSprite+Long+Range+RFID+reader.zip

 

Unzip the file:

 

0702 1

 

2.  You need install the MSCOMM32.OCX and TABCTL32.OCX. Then you can open the demo program.

 

0702 2

 

3.  Select Port(this number is the cable install on your PC, you can check it in Device Manager on your PC), then click Connecing:

 

0702 3

 
4.  Click Read Para,then you can see the device's Para settings:
 

0702 4

 
You can also revise the Para settings, then click Write Para to save your revise.
 
5. Click EPC  (GEN 2) Single:
 

0702 5

 
6. Click Identify to read the tag:
 

0702 6

I tried that first, before trying with an RS-485 adapter.  Are you sure that RFID works the same as our model?  Ours is an LSID_0704 and has the following label on the back:

At the very least, the colour scheme of the wires is entirely different.

 

This picture shows the DE-9 connector and its wires.  When we connected this to a USB-to-serial adapter and used the software, it should just say "Data line not plugged in or the device is not open":

When this didn't work, I tried connecting the wires that are labelled RS-485 to one of our adapters and connecting that to USB-to-serial adapter.  That's why I took this picture:

Still, nothing works.

We use a LSID_0702_RS232 device.

LSID_0704 is also RS232 interface, I think they are the same.

Did you use the demo program? Did you select the right COM number?
