Getting ready to make the move to Polisy.

Ordered the serial to rj45 adapter but then found a new, in box, serial PLM in my closet ?

I’m hardly the electronics expert but the photo of the end of the cable enclosed in the box only has 3 connections…The connector specifications show 4 connections in different spots.

Can someone explain this to me or do I have the wrong cable???

Thanks

The box with the PLM includes the serial cable. It's tucked away in the packing material. Most people overlook it as did I.

Let me know if you found it.

I know. This is the cable I got out from behind the flap in the box.

It works right out of the box, no need to modify the cable. One end goes to the 9 pin serial jack on the Polisy, the other end plugs into the PLM.

To verify that it's working click on TOOLS | DIAGNOSTICS | PLM STATUS

I have no doubt this is the correct cable and will be using it when it comes time. Was just wondering why the connector specifications don’t seem to match the cable end.

The 2 additional leads are not used. The Polisy requires 3 leads, input, output, and common

@drprm1 I can confirm the cable I have in a NIB (new in box) Serial PLM appears the same as yours.  I wouldn't worry about it. 

The TTL signals are +5 volt logic. Not buffered, can be damage if connected incorrectly and possibly stop the normally used RS232 signals from working correctly. The TTL signals are not in the older 2412S PLM and it included the same cable in the box..

That cable was used with many of the even older devices. Smarthome liked to keep using the same cable and basic pin outs.

You should be fine with the cable in the box. Just ignore the TTL signals as not needed.
