TRAUB TX7 serial connection

I managed to read from the tx7 controller to PC via serial connection.

But when i try to set the tx7 to accept incoming data from pc i have error 75 (tape recorder error).

If i disable RTR from machine parameters (55:00001101) i don't get the error but it's doing nothing when i activate program input and send .nc file via DNC precisionhttps://uploads.tapatalk-cdn.com/202...accb9bc08a.jpghttps://uploads.tapatalk-cdn.com/202...7374cd23d1.jpghttps://uploads.tapatalk-cdn.com/202...1ac9dc0cd0.jpghttps://uploads.tapatalk-cdn.com/202...766c6857e6.jpg

maybe it needs a % sign at Beginning or just a Blank Line.
Try to send the same Program back to CNC that you sent to the PC

I've tried to send the same program. But the tape error apears instantaneus after i pres the key combination. Maybe i need to make some other bridge in the DB25 connector to fool it that the tape player is OK. Or i dont know what could be the problem.
