YD 7001 RS Bus not reporting sensor status.


 

Purchased YD9401 and converted DR5000 to YD7001. I connected this to my layout that was using Lenz DCC. I have been able to control Locomotives. But
I am having difficulty reading the RS bus. When I use a LH101 Throttle to query a LR101 encoder (in this case number 83) all I get is "Active" displayed whether the occupancy detectors are active or inactive. If I Query it on the Lenz System I get "Active" plus the numbers of active sensors attached to the LR101 encoder. For example "ACTIVE ? ? 7" if sensor 7 is active.


 

Hi,

?

What is your DR5000 serialnumber ?

?

We found out, that large ranges in serial numbers have the components for the RS-Bus interface incorrectly mounted. As Digikeijs did not too much testing on their products, nobody ever noticed, until shortly when we overhauled the RS-Bus code for the YD7001.

Which is reportedly working fine wit all Lenz LR-1xx feedback units. LDT RS-modules are no good, they spread too much in their timing.

Here are the pictures, where right from wrong can be seen:? ( R16 and R1 in the pictures below )

Well I don't know what is going on. ?Based on these photos my DR5000 (Now YD7001) has the resistors in the proper orientation. When I hook up my test layout to a Lenz LZV100 everything reads out on the RS Bus without problems.
