5. Connection to the digital system
We recommend that you first configure the SwitchPilot 3 Servo
decoder completely and then install it on the layout.
5.1. Terminals
Fig. 4 shows the SwitchPilot 3 Servo with all terminals.
a) This pin header block is used to connect 8 RC servo drives (e.g.
ESU, Futaba®, etc.) and forms the outputs 1-8 of the Switch-
Pilot 3 servo.
b) The power supply of the SwitchPilot 3 including all connected
loads is realized vie the Terminals
Pw A
and
Pw B
. You can eit-
her use the track voltage or use an external power supply. We
recommend an external power supply, particularly for larger
layouts, because then the energy for powering the drives does
not add to the load for the command station or booster.
c) Connect the Terminals
Trk A
and
Trk B
to the track output of
the command station (or booster) that controls the SwitchPilot
3 Servo.
e) Input unit. The three buttons
PROG/OK
as well as (+) and (-)
serve to configure the decoder, as explained in chapter 6.
f) The display shows all settings of the decoder including turnout
address and status of the outputs. After a few seconds, the
screen saver displays the supply voltage.
g) Extension socket for the SwitchPilot Extension relay module.
h) These pin header blocks are used to connect 2 x 4 external
switch buttons in order to be able to specify the servo positions
directly without a digital center. Chapter 12 provides more in-
formation.
