M1KPAS Keypad

[JayD.]

Can the M1KPAS be connected to the M1DBH? If so, what Cat5 wire colors are used in the RJ-45 from the Elk-W018b?

The M1KPAS connects to the M1's data bus, just like a regular keypad.  The M1DBH instructions show how to connect the cat5.
 
+V:     Red   to  Brown (or Brown/White)
NEG:    Black to  White/Brown
Data A: Green to  Orange & Green (or Orange/White & Green/White)
Data B: White to  White/Orange & White/Green

Thanks for the response, just trying to confirm the wiring.  I have been having problems enrolling the M1KPAS.  No problems with the 4 other M1KP2's on the system.

Have you set it's address different from the other KPs?

 

[JayD.]

Yes, all have different addresses.  Have reconnected the Cat5 to the 4-wire also.  Will remove and rewire again.

A couple of other things to check:
 
- Did you remove the JP1 jumper on the M1KPAS?   There should only be 2 termination jumpers - one on the DBH and the other on the M1's JP3.
 
- Check for good crimping on the RJ45 end of the Cat5 cable.  Replace the connector if you have to.

What are you using the Elk-W018b for? The kpas should be wired from the dbh.

That's just the pig-tail cable that goes from the Cat5 to the 4-pin connector that plugs into the M1KPAS.

Got it, I was thinking of the M1 end of the data bus.
 
You can do a test for proper wiring by shutting the system down and testing the resistance between data A and data B of the rs485 at the m1 control board. It should be 65 ohms +- 10 ohms. If it is outside that range you can look for wiring or termination problems.
