5. Setup

This section details the physical installation and connection of your Roco 10808 Z21 Detector.

5.1 Device Layout and Connections

Figure 1: Top view of the Roco 10808 Z21 Detector. Visible are the 8-channel screw terminals (labeled 1-8), the power input terminals (P, N), the R-Bus and CAN-Bus RJ45 ports, and the Status, Error, and Program LED indicators.

5.2 Wiring the Detector

The Roco 10808 detector requires connection to your track sections, a power supply, and your Z21 central unit via the R-Bus or CAN-Bus.

1. Track Section Connections:

   The detector features eight screw terminals (labeled 1 through 8) for connecting individual track sections. Connect one rail of each isolated track section to its respective terminal on the detector. The other rail of each section should be connected to the common return of your digital system.

2. Power Supply Connection:

   Connect a suitable DC power supply to the 'P' (Positive) and 'N' (Negative) screw terminals. Ensure correct polarity. Refer to your Z21 system documentation for recommended power supply specifications.
3. R-Bus Connection:

   Use an RJ45 cable to connect the 'R-Bus' port on the detector to an available R-Bus port on your Z21 central unit or an R-Bus distributor. The R-Bus is used for transmitting occupancy information to the central unit.

4. CAN-Bus Connection:

   Alternatively, or in addition to the R-Bus, you can use an RJ45 cable to connect the 'CAN-Bus' port on the detector to an available CAN-Bus port on your Z21 central unit or a CAN-Bus distributor. The CAN-Bus offers higher data rates and is recommended for more complex layouts or when utilizing advanced features like firmware updates and address changes.

Important: Ensure all connections are secure before applying power to the system. Incorrect wiring can damage the detector or other components of your model railway.

6. Operation

Once properly connected, the Roco 10808 detector operates automatically to detect train occupancy on the connected track sections.

6.1 Occupancy Detection

The detector senses current draw in the isolated track sections. When a locomotive or lighted rolling stock enters a section, the detector registers occupancy and transmits this information to the Z21 central unit via the connected bus (R-Bus or CAN-Bus). This allows your Z21 system to display track occupancy on its interface and enables automated control functions.

6.2 RailCom Functionality

With RailCom enabled on your Z21 system and RailCom-equipped locomotives, the detector can not only report occupancy but also identify which specific locomotive is present in a detected section. This advanced feedback is crucial for sophisticated automation and operational control.

6.3 LED Indicators

The detector features three LED indicators on its top surface:

• Status LED: Indicates the operational status of the device. A steady light typically means normal operation.
• Error LED: Illuminates or flashes to indicate a fault or error condition. Refer to the troubleshooting section for common error interpretations.
• Program LED: Indicates when the device is in programming mode, for example, during firmware updates or address configuration.

6.4 Firmware Updates and Address Configuration

The Roco 10808 detector supports firmware updates and unit address changes directly through the Z21 central unit, typically via the CAN-Bus connection. Consult your Z21 central unit's manual or the Roco website for detailed instructions on performing these operations.

7. Maintenance

The Roco 10808 detector is designed for reliable, long-term operation with minimal maintenance.

• Cleaning: Use a soft, dry cloth to gently wipe the exterior of the device. Do not use liquid cleaners, solvents, or abrasive materials.
• Storage: If storing the device for an extended period, disconnect it from all power and bus connections. Store in a cool, dry place away from direct sunlight and dust.
• Connections: Periodically check all wiring connections to ensure they remain secure and free from corrosion.
