4.2. Light signals

The lamps for the signals are connected to the outputs A1 to A8 and B1 to B8. At the ports, each "+" terminal refers to the common
plus pole.
WARNING: Please note that LEDs may generally only be connected to the decoder with a series resistor for current limitation,
regardless of whether they are dimmed or operated at full brightness. The resistance value depends greatly on the LED type
actually used, meaning no accurate data can be provided here. However, commercially available LEDs can normally be operated
with a series resistor of approx. 2.2 - 10 k . If in doubt, start with a higher resistor value.
2 to 4 signals can be connected to the Z21 signal DECODER. The Number of signals can be set via the programming button
Option 2 – Set number of signals) or CV #40. This is even simpler using the Z21 per LINK, where the number of signals can be directly
selected in the "Settings" menu.
Depending on the set number of signals, the signals are distributed as follows on the terminals:
• 2 signals: Up to 8 outputs are available per signal, namely A1 to A8 and B1 to B8.
• 3 signals: For the first signal, up to 8 outputs (A1 to A8) can be used. Two further signals can also be connected to 4 outputs
respectively, namely B1 to B4 and B5 to B8.
• 4 signals: Up to 4 outputs are available per signal, namely A1 to A4, A5 to A8, B1 to B4 and B5 to B8.
