The Roco Cranes I have (DCC - rail mounted and dockside) can be EITHER 6 or 7 and operate in 14-speed step mode which is easily set for that loco number with a multimaus.
You probably also want to look at using 'Library Mode' and to call it CRANE 8-) ... then it will remembered and copyable from one handset to another.
(The library is held INSIDE each multimaus, and can hold the name and settings for 64 locos - they DO NOT HAVE TO HAVE SHORT ADDRESSES as 'implied' by the manual only refering to CV1 .... Long addresses are just as usable!!!! (Not realising that stopped me using the library/name mode for several years!)
I always use the (dock) cranes via the separate digital interface and joystick - which is easy and logical with the fixed cranes.
This forms a separate'dcc'/control system, totally spearate from the track/accessory bus dcc sysytem. 16Vac power supply used + 1 std Joystick
The mobile crane - assume it can .must be usable anywhere on the track (accidents don't only happen where you wannt them) means that No.6 or 7 is reserved for the crane, and not used by any other device/loco/
SOMETIMES, 'control' is lost - and a Power OFF REset is needed - for the crane decoder... but most usually, someone has accidentally changed number with the joystick.
F0 is another name for 'LIGHTS On/off' - sometimes labelled as F10 (Bachmann EZ ??? ) - it is the [ * OK ] key on the multimaus. Speed Steps Menu + Cursor Left to cycle
You are correct that flashing green meand it is receiving commands to that address ( With the Joyustick, the FIRE button swaps it between Addresses 6 and 7, so it is important to watch it. THe LED goes RED when the Electromagnet is operated to open the bucket.
With the Joystick -because it uses Analogue to Digital conversion, it is important to use the trim pots to set the ZERO positions ! Not a problem via Multimaus.
Rutger Friburg, the designer, also suggested opening up the sides of the bucket to turn it into a log-handling grab - which is how we let visitors operate it at shows ... moving twigs in and out of stake wagons.
