Need Help!- Fanuc OM 086 Alarm

[ThomasS]

Hello,
stopped after 4 weeks, I can not send more data is received at the PC or cable has been tested, all voltages are ok, and all other functions are ok. PC is changed, no change in Alarm.
On what is this?
Thank you for tips.
Best Regards from Germany,
Tom

086 is DR SIGNAL DOWN. Check the resistance between pins 6, 8, and 20 on the CNC end of the cable. All 3 should be jumped together.

Hello,
i checked the cable, 6,8, and 20 are jumped togehter. This Cable works last year...(and its fixed mounted)

Hi, perhaps a different solution:
how can I activate the second, unused interface? M74 connector (instead of M5) on the Mem- board. The parameters 0002, 0038, 0050, 0552/0553, I've adjusted, however, the I / O port. No success, nothing, no Alarm. No function...
Can i use this Port, the second interface? Or is unsuitable for PC connection and supports read-only devices as punchers and readers?
Greetings,
Tom

par 914 bit4 enables reader/puncher interface 2
You may have to replace the 75188 or 75189 chips on the memory board.
If you tell me the memory board part number I will tell you the locations.

Hello Memoryman,
i have found the two 75188/89 on the Board. At first, i will check if interface 2 is possible to use.
Many thanks for this Parameter, i had not seen yet.

Hi,
after I had changed the parameters of 0914 / 4, a little bit of communication is there. My program says "Hardware detected a framing error" or "Hardware detect a parity error". Another software receives the data, but that's not the right format...
Something does not seem to agree, data is being sent, but the PC shows only trash. 0002/0012/0038/0050/0553 and 0914 with parameters are all adjusted, 7 Bits,2 Stops, Even. Does anyone have any idea? Have i forgotton a parameter? It certainly seems as if broken, the first port, but what I must do in order to use the second port can?
At the first port I had used the (easy) Three-wire communication cable, it may be that I need the second port of a more wires?
Greetings,
Tom

I forgot to mention,parameter 901 bit 6 is the option for port 1.
914 bit 4 is for port 2.
Send me a parameter file and I will tell you what the problem may be (could be on the memory board). Also, is the SETTING for ISO/EIA correct?

In the moment I can`t upload a current file... 0901 / 6 was set originally, so it went with the Port 1 to 4 weeks.
Since the second port is not used, I would like to take the place of the defective first.
Later i will replace the 75188/75189, but first I want use the other port, if possible.
Is it possible to set both ports (901 and 914) to be active, or is only one at the same time?
I send you tomorrow a file.
Best Regards, Tom
