Setting of end-positions and the speed of movement
1. Power on the module, and make sure that the servo(s) is/are
connected
2. Hold "PROG" for max. 1 second
3. "LED1" lights up to indicate that "Servo 1" is being programmed
4. Use UP/DOWN to set the first end-position
5. Briefly press "PROG"
6. Use UP/DOWN to set up the second end-positions


7. Briefly press "PROG"
8. Use UP/DOWN to set the speed of switching between the previous
two end-positions
9. Briefly press "PROG"
10. "LED2" lights up to indicate that "Servo 2" is being programmed
11. Repeat steps 4 to 8 for the second servo as well
12. Briefly press "PROG" to exit from programming mode
Quick programming of digital addresses
Digital addresses can be set up easily without CV programming by using
quick programming.
1. Power on the module
2. Hold "PROG" for at least 3 seconds
3. "LED1" flashes briefly to indicate that the address connected to the
output "Servo 1" is being programmed
4. Set the desired switch address on the digital center
5. Issue the switch command (in any direction)
6. "LED1" lights up for longer, indicating that the address has been
registered
7. Briefly press "PROG"
8. "LED2" flashes briefly to indicate that the address connected to the
output "Servo 2" is being programmed
9. Repeatedly issue the address (steps 4 to 5)
10. Briefly press "PROG" to exit from programming mode.
After exiting from programming mode, the decoder can be controlled
from the digital center.
