Determination Of Use And Function; Installing The Z21 Signal Decoder - Roco and Fleischmann Z21 Manuel D'utilisation

2. Determination of use and function

The Z21 signal DECODER has been developed for use on model railway systems with DCC control centres for switching light signals,
each equipped with up to 8 LEDs with a series resistor and common plus pole.
The Z21 signal DECODER has been specifically designed for use with the Z21 product range, but is also compatible with older ROCO
control centres as well as with DCC control centres from other manufacturers. In the latter case, however, the addressing mode should
be set to "RCN-213", see also section Operation on control centres from other manufacturers.
Features
• 2 to 4 signals can be independently configured and operated
• Over 40 predefined signal configurations from different countries can be selected
• Programmable with RailCom on the main track (POM)
®
• Controls switching commands for basic and extended accessory command
• Signal addresses 1 to 2040 programmable (in groups of four)
• Can be configured and updated via zLink
• Optional power supply
• Secured against overload and short circuit

3. Installing the Z21 signal DECODER

Install the Z21 signal DECODER at an easily accessible location with adequate ventilation to facilitate carry-off of waste heat. The Z21
signal DECODER should never be placed close to strong sources of heat such as radiators or places subject to direct sunlight. This Z21
signal DECODER has been developed exclusively for dry interior spaces. For this reason, do not operate the Z21 signal DECODER in
areas subject to major temperature and air humidity fluctuations.
TIP: Use screws with a round head for installation of the Z21 signal DECODER, e.g. 3 x 30 mm.
