Anybody have the wiring diagram to make up a cable for this machine/control? The machine has a 25pin female port on it inside the tape reader.

Thanks!

Be careful... IIRC some of the old Yasnac's had DB25 connectors that were intended for use with a Facit parallel punch, not serial I/O.

But if it truly is a serial port, the cable should be:

DB25M (CNC) <------------> DB9F(PC)

1 <---------- shield --------- (no connection to PC)
2 <---------------------------> 2
3 <---------------------------> 3
7 <---------------------------> 5
4<>5 (CNC end only)
6<>8<>20 (CNC end only)

Thanks!

Any tips on how to initiate the program transfer to the machine? this control is new to me and my documentation is minimal.

Hold off on making that cable. I just found another diagram and now I'm confused.

Ok so it looks like the serial port on the machine is in face for a tape puncher.... Any way to confirm for sure that this machine does not have RS232 program transfer capability?

I googled Yasnac 2000g-II serial and got this.

IIRC, these guys had one or two of these Yasnacs, so I think they know what they're talking about. You might go to Fry's or Radio Shack and get a cheapie RS232 tester and try punching a program to see what pins flicker... if it's 15/16 as opposed to 2/3 (the usual xmit/recv pins) I guess I would try their cable.

I got a tester and tried to punch a program. No lights came on at all.

I checked all the parameters that relate to RS232 and they are set to what that website was showing.

I don't know what the history of this machine is, but it doesn't look like the tape reader was used for quite some time. The 25pin port beside the tape reader says "P.O." Beside it. Hinting at "punch out"? For a tape puncher perhaps?

Try this, Plugs were configured backwards

Use your tester at the computer end, I will not operate on the machine end

You have to make a cable to communicate, Never Have I been able to go any faster than 300 baud

But think about it, Lathe Programs are generally short
Connector at machine
Frame Ground pin 14
Ground pin 19
Transmit pin 15
Receive pin 16
jump 17&18

Be very careful fiddling with this stuff, One mistake not documented will render your machine worthless
following is the complete parameter set out of my SL-1 H

Reference only if you get yourself in trouble

Suggest once you get it operating, Start receive 300 baud 7,E,2

Rotate to Edit, Simultaneously hit OFS and TAPE OUT, this will punch your parameters to you PC or LAPTOP

Entire set for my SL-1s, Sl-2 and SL-3 these communication parameters will be valid for all with 2000 GII

Thanks for all this. I will give it a go

I will be using a 25p to 9p converter to go to my USB serial 9p adapter. This wiring configuration should still be ok with my setup?
