For serial communications on Port 1 settings are:
TVON =      0         Parameter    0002   1xxxxxx1
ISO =         1                               0038   01xxxxxx
I/O =           0                              0050    Not used
PWE=        1                               0552   10
TAPEF=     0                               0553    Not used


For serial communications on Port 2 settings are:
TVON =     0        Parameter      0002   Not used
ISO =         1                               0038   xx01xxxx
I/O =           2                              0050   1xxxxxx1
PWE=        1                               0552   Not used
TAPEF=     0                               0553   10

x - Does not matter how these bits are set.

Fanuc default protocol is 4800, E, 7, 2
The procedure for reloading a "Brain Dead" 0 Control when you have a copy of the Parameters on Disk or PC is:

1.   Set the E-Stop ON. (Button in)
2.   Select MDI mode.
3.   Set PWE = 1
4.   Set Parameter 901 to the correct value.
5.   Press the DELETE key when prompted to by the controller. (You must delete the files in order to continue)
6.   Cycle power.
7.   Set Parameter 38 to the correct value.
8.   Make sure EIA/ISO = 1.
9.   Make sure I/O = 0.
10. Cycle power.
11. Set the PC's protocol for 4800,E,7,2. (When parameters are lost, the controller defaults to this protocol)
12. Select EDIT mode.
13. With E-Stop in and Parameter Page selected, press EOB and INPUT together. (LSK will start to flash)
14. Send the Parameters from the PC. (When the data begins to flow, LSK will change to INPUT and flash)
15. When INPUT disappears, cycle power.
16. Select Diagnostics Page.
17. Release the E-Stop.
18. Press INPUT only.(LSK will flash)
19. Go to the PC and send the Diagnostics. (When data begins to flow, LSK change to INPUT and begin to flash)
20. When INPUT disappears, cycle power.
21. Set Keep Relays as required by the Machine Tool Builder.
22. Cycle power.

Remember that when working with a brain dead controller that the CRT may display EDIT mode regardless of what mode is actually selected so go ahead and put the machine in MDI mode and enter the necessary parameters.

If Alarm 085 is continually issued, double check the PC's protocol and check Parameters 2, 10, 38, and 552 to make sure the controller defaulted to 4800,E, 7,2.

When viewing the Diagnostics on a PC, N10300 = D0300 and so forth.
