Fanuc 11 crt problems

Hello.
The company i work for owns a very large cnc-mill with fanuc 11m as the controller.
Unfortunately the monitor sort of burned itself out a couple of days ago.
We have had a tv-repairman here to try fix the problem but so far no luck.

I am now considering replacing the entire monitor with something a bit more modern, but to do this i need to know how the monitor talks to the machine.
That is, levels(ttl, analog...) and hopefully a pinout of the honda-connector that the screen hooks up to.

Replacing the monitor with a spare fanuc monitor is apparantly horribly expensive.

Any help would be most appreciated.

kindly bofr

Contact DMT CNC (www.dmtcnc.co.za)
They supply 15" replacement LCDs (colour) for a third of the FANUC CRT price.
Easy to install and looks brilliant.

D sub 15 vga -> honda 20 pinouts:

vga honda
1 -> 1 (RED)
2 -> 4 (GREEN)
3 -> 5 (BLUE)
10+11 -> 8+9+10+11+12 (GROUND)
13 -> 2 (Horizontal sync)
14 -> 3 (Vertical sync)

4,5,6,7,8,9,12,15 (vga not connected)
6,7,13,14,15,16,17,18,19,20 (honda not connected)

Tested: fanuc 11m+fanuc 15m

Pinouts measured from retrofit monitor cable. (honda 20 pin, d-sub 15 pin adapter cable)

If you can find any older multiscan TTL monitors, you can sub one in fairly easily.
Unfortunately they are getting rare and most have gone for scrap.
Al.

we have 3 of our machines with retro-fitted LCD's. From about 1990 onwards the monitors are just VGA so you can fit in any common VGA monitor using a VGA to FANUC converter cable (using the above pinout). We just cut the FANUC connector off the cable and hard-wired in a female VGA connector :)
for older monitors that run at 15k or 25k just use a scan converter. They are found on ebay and commonly used to convert arcade machines (which run at 15kHz) to run VGA monitors.

Hi,

can I just confirm that pin 18 on the honda plug does not go any where on the 15 pin plug.

On the pinout diagram, it says pin 18 is not used, however on my plug, it is grounded to the Blue and Green grounds on pins 11 and 12 ???

Thanks fordav11, I believe I will be going down the road of using the scanner for our system, as it is 1990!!! I cant beleive its that old now.

its just a ground. unused pins can be grounded or left open.

For video connectors wiring get APP from google play store " Monitor experts" cnc retrofit monitors.
