Da wäre ich auch sehr daran interessiert. Bitte in jedem Fall deine 
Erkenntnisse hier posten. DANKE!

roberto, freue mich wenn es läuft! wenn du noch etwas rasufindest bin 
auch ich immer daran interessiert :-). erwähnenswert finde ich noch, 
dass eltako selbst kein betriebsgeheimnis aus ihren komponenten macht 
sondern meine bisherigen anfragen immer nett und kompetent beantwortet 
hat. für mich immer wieder grund genug gerne zu eltako-komponenten zu 
greifen.

I am struggeling to teach-in an Eltako FUD14 dimmer (together with 
FBA14) bus coupler. I'm sending the telegram directly over RS485 
(baudrate 57600).

I created a small python program to send the telegram, but doesn't seem 
to function. Also sending it directly trough a terminal program 
(realterm) doesn't work.

The FUD14 doesn't react to the teach-in telegram, and red led keeps 
blinking after sending the telegram.

I tried following telegrams:
0xA5, 0x5A,0x0B, 0x07,0x02,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x00,0x15]

According to Eltako documentation, the teach in telegram should look 
like this:
0xA5,0x5A,0x0B, 0x07,0xE0,0x40,0x0D,0x80,0x00,0x00,0x00,0x0B,0x00,0xCA

 
import serial                          # import the module 

#com port settings for eltako
#tested with moxa uport usb to rs485 adapter
ComPort = serial.Serial("COM5")
ComPort.baudrate = 57600
ComPort.bytesize = 8
ComPort.parity = 'N'
ComPort.stopbits = 1

     
#set fud14 address to "0B"
teachTelegram = [0xA5,0x5A,0x0B, 0x07,0xE0,0x40,0x0D,0x80,0x00,0x00,0x00,0x0B,0x00,0xCA]

#set dimmer on(0X09), dim with max speed (0x01) & to 100% dim val (0x64)
dim100 = [0xA5,0x5A,0x0B,0x07,0x02,0x64,0x01,0x09,0x00,0x00,0x00,0x0B,0x00,0x8D]

#convert to an array of bytes
data = bytearray(teachTelegram)
print("raw data: ",data)
No = ComPort.write(data)
print(No,"bytes written")

#close com port when finished       
ComPort.close()

Any ideas?
