Rod... Just a review from page 25 in the T9000 manual... I know you've read it a dozen or more times. I've added the (locomotive number) in addition to the work address.
Since service mode programming can change everything including addresses, an extra
keystroke has been added to confirm entering this mode. For this example, the decoder
address will be set to the locomotive number of your choice. Make sure that all other locomotives are turned off.
All service mode programming is done with following keystroke sequence, no matter
what CV is to be programmed.
Start by pushing and releasing SPR. Notice the $ sign and SPR are both flashing. Imagine the dollar sign as a warning about the “cost” of accidentally programming more than one locomotive. It’s corny but it does serve as a reminder to check that only the desired locomotive is powered up.
Push the SEL key to confirm and notice the flashing has stopped.
The CV to be programmed is entered first. The T9000 uses the * key to enter CV numbers. Since the address is CV1, start by pushing by pushing the * key.
Cn means configuration number.
Now push 1, then * again.
Enter the value for the CV, by first pushing the # key.
Notice that the Cn is now just C with the colon flashing.
Enter the desired address, (Lovomotive Number) for this example and then push # to transmit the address.
The colon will stop flashing. The AirWire decoder will beep twice if the (locomotive number) address is in the range of 1 to 99. If the (locomotive number) address were higher than 99, theAirWire decoder will beep 3 times.
At this point, you have two options.
(1.) Enter another CV number, starting with the * key again and repeat the same sequence as
above. The * key does not end this mode. Pushing it means you want to enter another CV
(2.) Exit the programming mode by pushing the SPR key. This is the only key with which
you can exit the service programming mode.
Rod, these are my procedures from here down...
At this time, I generally everything off. The turn the receiver and transmitter back on. If the LN # you programmed in is on the LCD, you should be linked and all functions working.
Hope this would give some help...
