How to connect between 8051 training kit with RIDF reader

[henrjay]

This is my 8051 training/development tool integrated with RS232(max232) and others IC

Now my problem how i connect RIDF reader(shown below) with my microc?


Usually, i use rs232 to program or 'burn' hex file into 8051,from what i see from user manual

http://www.cytron.com.my/usr_attachment/RFID-IDR-232N_User's_Manual.pdf

this RIDF reader consists of RJ11(connected to reader), USB to PC and RS232 to PC as well.

Unfortunately, i using laptop which means no serial port and i solved it through using RS232 to USB

I can't figure out how to connect this two devices.
But when i see this video
[youtube]VbJQbU1_kvg[/youtube]
it connected with 4pin into 8051/PIC board, are it means we just connect this RS232 to my rs232 instead connect to PC

anyone experience before then can answer me?

Sorry for my broken English.

The RFID tutorial: http://tutorial.cytron.com.my/2012/07/30/wireless-rfid-reader-using-xbees/ shows it needs UART to RS232 shifter. Since, the RFID works directly on the RS232 port on the PC directly, then, I think it requires the shifter. If thats the case, you can directly connect it to the RS232 connector on your board and power it using 5V connected to the USB cable.



-- From the tutorial website.

**Since the RFID reader is a RS232 peripheral device that can interface with computer directly but not microcontroller or XBee in this case (since TTL UART is used), a level shifter circuit likes URS232A is needed.

They connect directly because they have rs232 to ttl level shifter using diode, transistor and resistoras shown in the last picture

ok, that means i can directly connect the rs232 connector of rfid reader to my 'female' rs232 port right?
since it integrated with uart to serial port already.

thanks for your explanation of that '4pin', in my case i didt use it as you stated on your reply.

My further question is rs232 connector of the reader is female or male since my connector is female?
and in that pdf file attached i hard to see clearly. @.@

from this image, if i using PIC Start-up Kit provided by cytron which is no rs232 provided

can i refer this schematic?

because the training kit i using now got some bug and it is 'old'
sometimes it will failed to burn into 8051 eeprom, i want to 'obsolete' this 8051 already @@.

that image using 8051, but i think it is compatible right?

Yes. you are right.

Its a female connector.
