We are trying to hook our LC-30 w/ 5020L controls up to a computer to send programs not even drip feeding.

We have a connection through an rs 232 port on the machine.

i have the parameters set to match on both the machine and the PC.

We go into edit aux and then to DATA PIP, then to READ.

we type TT:, "file name" and the press WRITE

machine thinks about 45 seconds

then we get "ERROR 2561 RS232C ready interrupt time out ERROR"

can anyone help us figure out what we are doing wrong?

the machine was recently moved and the plant where it was had a peminant DNC that feed multiple machines. The RS232 port worked a week ago.

We are using a single PC and our own cable.
machine came with an adapter hooked to rs232 and we have tried with and without it.

Thanks in advance
