Encoder to Skyko

[bbrreid]

can anyone help with Heidenhain encoder Rod 250 wiring to Skyko 100 board.
the board has connection EncA , EncB , Ena , ref- , ref+ , +5v , Gnd.
I dont have the schmatics for the 250 but the other Heidenhain encoders have
a1, a2, a0, 5v sensor, 5v etc. the Rod 250 has brown , green ,pink ,black ,
and brown/green, can anyone tell me what goes where.
I also have a BEI encoder 4H-SB250 for "Z" axis with black,yellow,green,red,orange,blue.
and need to know the connections for this one
thanks

Not very good news, I show the ROD250 as low level sine wave, which means if this is so, you need intermediate electronics to condition it and square it up to TTL level.
BEI colour codes are shown as:
Yellow ChA
Blue ChB
Orange Ch Z (marker)
Black Common
Red Supply
Green Case ground

Thanks Al once again a great help.
I did wipe more dust of the Heidenhain plate and the numbers are
Rod 426. 000B - 250
Id No. 295 434 35
Sn. 388 268 T9
is this better news ?
cheers

The 426 shows as TTL so you are in luck.
A = brown
/A = green
B = gray
/B= pink
Z = red
/Z = black
+5 = brown/green
comm = white/green
white & blue are sensor, disregard.
If using in the single ended mode, do not use the / signals.
