Roco and Fleischmann Z21 Manuel D'utilisation page 43

It has been ensured for all prepared signal configurations that the most important main lights (usually red, green, yellow) are located as
far as possible on the first four terminals, and that additional lights or additional signals are located on the rear terminals. This makes it
possible to operate several highly complex signal systems even with only four terminals if the signal screens are only partially equipped,
as is often the case with the prototype. This ensures that the connection possibilities on the Z21 signal DECODER can be optimally and
highly-flexibly utilised. Here is an example with SBB signals:

• On the left is a complex SBB main signal System L, and a fully-equipped SBB distant signal.
• In the middle image, the distant signal only uses four lamps, and therefore there is still space for another, partially-equipped SBB
main signal System L.
• On the right, two partially-equipped SBB main signals System L can be operated, and there is even still space for a distant signal
and an SBB dwarf signal with departure permission.
All the main signals shown in the example work using the same signal configuration (Signal-ID 192 "SBB System L main signal") and
merely differ in the number of lamps available. All three connection variants shown require max. five CV variables for the configuration,
namely CV #40 for the number of signals and CV #41 to #44 for the selection of the required signal configurations. This is of course
even easier using the Z21 per LINK, namely with no CV programming at all.
Conversely, the Z21 signal DECODER can also be used to present highly complex and unusual signal screens through the creative combi-
nation of several single signals.
Example: In Graz Hbf., several single signals were combined on one screen
On the left-hand side of the screen is the main signal including the substitution signal and the shunting signal. The distant signal is
positioned in the centre, and on the right is the brake test and departure signal (small green lamp).
