In Antwort auf: 'On the layout' programming of old DCC turnout decoders=======================================================In order to program old DCC turnout decoders (like the Maerklin 6087& 6074 types) using the IB, the following procedure must be used:1) reset the IB;2) now CAREFULLY AVOID controlling any turnout device!!! (No Keyboard mode turnout key should be pressed. This is EXTREMELY important);3) take control of any DCC Lok in address range 1..111 (I haven't checked long addresses - in fact, I've only checked address 111 (14 DCC) and 3 (128 DCC)). I guess it is also important that NO OTHER Lok (particulary no other non-DCC Lok), except this DCC one, be in the refresh cycle (also: given the new Purging feature, in absence of commands and assuming default configuration and Lok stopped, packets for this DCC Lok would be generated by the IB for only about 2 minutes, therefore the programming procedure must be completed within this time interval);4) eventually (still being careful NOT to control any turnout, particulary when pressing the [Enter] key (it should not be pressed twice!)) you can change the IB Keyboard mode turnout base address to one of the addresses which you'd like to control through the k87 which you are about to program;5) now press the gray programming key on the k87 decoder which you'd like to program to a specific address AND KEEP IT PRESSED;6) press and release on the IB one of the (green or red) turnout keys which correspond to one of the turnout addresses which you'd like to control through the k87;7) release the k87 gray programming key.For example: in order to program a k87 for turnout addresses 1-4,you can press - while keeping the k87 gray programming key pressed -any key of the first two "rows" (of the IB keys which control turnouts).In order to program one more k87, it suffices to press [Stop], wait acouple of seconds, press [Go] then repeat steps 4..7 (there is no needto repeat steps 1..3 - a Power Off cycle suffices).This implies that a k87 only accepts programming provided threeconditions are met:a) there is (was) a DCC Lok packet;b) the gray key of the k87 is pressed;c) this one is the first turnout DCC packet since Power On.(For your information: the Mrk manual says that before programminga k87 on the layout, the reset key of the 6027 (on the back) must bepressed: this only causes a brief Power Off cycle - besides clearingthe refresh cycle. N.B.: a 6027 does not use the standard DCC idlesignal.)N.B.: if you forget step 3 (that is, if there is not a single DCC Lokin the refresh cycle), then you'll most likely cause a "bad programming"of the k87. It shall then be necessary to "recover" it by programming iton the PT: Register Prog., Register 1, Value = 128 + decoder address.E.g. program register #1 to the value 129 in oder to have that turnoutdecoder control turnout addresses #1..4.For other turnout addresses, the computation is:((turnout address - 1) / 4) + 1where 'turnout address' must be the first turnout address of that decoder.For example, for a turnout decoder controlling turnouts 17/18/19/20:((17 - 1) / 4) + 1 = 5therefore, you must program register #1 to the value 128 + 5 = 133.
