I have a 1991 HT20SII with the Yasnac LX3 seikos multi control
It had been receiving NC programs via RS232 port but yesterday it will only send the program and no longer receives. I tested the cable and computer by sending to another machine and it is working fine, I can receive a program from the machine but it just blinks receiving data never ending or giving an error? what can I do from here? located in AZ Thanks
