Locomotive/Locomotive function decoder from firmware version 3.12
Supplement 3: Unamplified function outputs
As in case the unamplified function outputs (logic level 0 V - 5 V, max. 20 mA) cannot switch higher loads, switching
amplifiers (MOSFET, bipolar transistors or the like) must be provided for consumers, which either require a higher supply
voltage (> 5 V) or a higher current (> 20 mA).
The SUSI connectors ZCLK and ZDAT can, if available, alternatively always be used as unamplified function outputs:
* See supplement 1
Please note that it does not matter here whether the decoder also offers these function outputs on other solder pads or
interfaces! The additional activation of the connectors ZCLK and ZDAT does not change anything on these solder pads or
interfaces. If a decoder offers for example AUX3 and AUX4 amplified on corresponding solder pads resp. interfaces, these
outputs are additionally available unamplified at the connections ZCLK and ZDAT, if CV137 | par088 is set accordingly.
