Sending command to accessory decoder not quit consistent

Using signal in patten mode the packet send to the decoder

Send to the XpressNet bus

52 01 8c CRC // turn off "output 1" output group 2

"52" = Acc command
"01" = Acc address
"8C" =
    bit 7-4 = "1000" bit
    bit3
      "0" = activate output ( Don´t think this is right )
      "1" = deactivate output
    bit2-1 the 4 output group
    bit 0
      "0" = "output 1"
      "1" = "output 2"


This command then turn off "output 1" output group 2

The using signal without signal patten
52 01 8c CRC // turn off "output 1" output group 2
52 01 88 CRC // turn off "output 1" output group 0
52 01 8e CRC // turn off "output 1" output group 3
52 01 8c CRC // turn off "output 1" output group 2
52 01 84 CRC // turn on "output 1" output group 2

Then for turnouts
52 02 8e CRC // turn off "output 1" output group 3
52 02 87 CRC // turn on "output 2" output group 3

Then why does signal in patten mode turn off the output?

Hi,

> Then why does signal in patten mode turn off the output?

My test results to this issue are the following: it is not possible with lenz to control the outputs seperatly. The paired outputs always want to react as a switch.

So if i turn on the red one of the first switch we have to deactivate the green one first. This is strange but if we are not doing so the cs will send out the last command over an dover again to the tracks. This can be seen with a tool like showDCC. So I decided to turn off the other outputs before turning on another one. This will prevent the looping of the last command. Maybe this is a bug in the lenz cs, I don't know.

So in short: if one output is activated the other one on this switch is deactivated.
