I have a daewoo linx 200 and there is not sending data , i use an Rs232 tester and looks like the ic (chip) for output is not working .


Does any one know the IC number ?

Just want to clarify. Does the communication works one way but not the other? i.e. will read but not punch? How recently was this functioning? FYI. You will not be able to replace the RS232 related components on 21TB easily. They are surface mount type components. Please also post main CPU board number.

YES the machine READ but not PUNCH , it was working monday
the machine is working at this time so i can't get the cpu board # , but i know that the connector on the board side is XJD5A and the terminal to follow is "11" , i have to take the board and follow the circuit from there.

You say the machine will punch but not read. What happens when you try to read? Do you get an alarm?

sorry i correct my self
No the machine read (receive ) programs but do not send so y can't get out the programs from the machine .

What happens when you try to PUNCH? Does OUT blink on the CRT? Any alarms?
