TT-4 issues

Hi all.
My TT-4 is giving an error. TT PLC not set.
Last time I used it successfully was last fall.
When I connect the cable to the control I I can see plc input 772 is going green, not 771.
As a test I try the KP-3. 771 lights up green.
Both devices cycle 769 when the probes are touched.
Am I missing something?
These sit in a drawer untouched and I have made no changes since getting the control installed.
Thanks for the help.

Set Parameter 44 = 50769.
Contrary to what the manual says, current software requires that you explicitly set Parameter 44, even if the tool setter uses the same input as the probe, which is already specified in Parameter 11.

Thanks, will go change it.
Question - was this mentioned in the release info for the code update as something that may need to be addressed at the machine?
I'm terrible at reading all the fine print.

Parameter 18 is set to 50771 (KP-3 connected trips this one)
Is there a new parameter to use for the 50772 (this is the one I observed going green when connecting the TT-4)

Parameter 257
The manual still says that parameter is for a "TT1", but in reality it applies to any tool setter.

Alright made both suggested changes and all is right in my world.
Thanks you Sir.

Well, seems only a partial fix.
This screenshot is showing the result of loading my reference tool in order to find Z ref.
Measuring a tool from the F3 Auto Ref works.

See Parameter 43
