# Trigger the LocoNet Find Transponder interaction
|
|
#
|
|
# The DCC address being found is hard-coded into this sample script
|
|
#
|
|
# After sending the LocoNet Find message, the script also
|
|
# commands a few DCC packets to be sent. This is in case
|
|
# the command station is not currently addressing the
|
|
# decoder, e.g. if it's not currently on a throttle. Transponding
|
|
# decoders only reply when they receive a DCC packet addressed
|
|
# to them.

# A find request to (long)433 should send E5 09 40 03 31 00 00 00 61
|
|
# and the hardware should return E5 09 00 03 31 00 20 00 01
|
|
#
|
|
# For (short)10: E5 09 40 7D 0A 00 00 00 24
|
|
# and reply: E5 09 40 7D 0A 00 20 00 44
