FANUC 10M, RS232 Zapped by Lightning
Thank You Again GUHL for help on Fanuc 10M, EMG Display On (problem solved).
(The EMG problem was an initilizing parameter input mistake, GUHL's option answer helped lead us in the correct direction.)
After woking fine for 15 years a lightning strike zapped the RS232 on this Victor Mill 10M.
An office PC was also damaged, not the one hooked to the Victor.
New cables do not help. The cables tested OK with a tape puncher (baud rates were changed to suit). A lot of testing was done and it looks like the Victor 10M is the problem.
In the forum archives, #2042 dated 10-17-2008, has this problem.
(http://www.cnczone.com/forums/archiv...p/t-66523.html is the address)

The first reply is from, Al_The_Man, he wrote:
"On the 10, there is usually two ports, one on the MB and one on the operator panel, you can use the appropriate parameter to swap the port over, failing that you could trace the RS232 pins on the Honda socket and look for any IC close by that have 1488 or 1489 on them, I cannot remember if they use this common IC or not, but any IC connected to the port could
be replaced as an attempt to cure it if you cannot find the other port."

(Back to the problem) There is a small Honda socket labeled CM4 in the CRT/operater cabinet.
If possible could someone help with:
Is the CM4 the other RS232 port.
The Honda socket on the main (mother) board that goes to the 25 pin Male RS232 looks identicle to the socket in the CRT cabinet, could it be plugged in with the same wire connections.
How many parameters would have to be changed and is anything else to be considered.
This is a wonderful forum, Thanks to All.
