hi, my name is Milton Suarez, and i work in a manufacturing plant. I have two HITACHI HT-50G, with SEIKI-SEICOS A10L control. We were uploading a part programm, and there was an electric overload between the p.c and the cnc...obviusly, the port for comunicate both, was damaged, and since that moment up to now, we couldn´t transmit anymore... neither uploading nor downloading. We had the same problem in another machine with Fanuc control, we solved it changing the port conection in the control from the RS-231 com 1 to rs-232 com2... in this way, we continue transmitting without problems. My question is, do Hitachi machines have other COM port as alternative? I opened the back gabinet, and i saw that there is a label where you read "RS-232 C2", but it belongs to a printer, and the conection is not the same as the common RS-232 serial 25 pin conection.
As you see, i´m lost. i need to transmit again, i don´t know if i could use this other port, and if not, i´m afraid that i not be abble to fix the broken port.
Any help that you could give me, is the most welcome.
Thank you !!!!
