2.5 Extending Module Connection
2N Helios
®
features an easy installation of extending button modules. Extending
modules are connected using a single cable (included in every extender delivery) in a
chain pattern (every additional unit is connected with the previous one). Each
extending module has two connectors – an input connector (for connection towards the
basic unit) and an output connector (for connection of another, more
2N Helios
®
remote unit). Be sure to maintain the correct orientation of the units and avoid
connector mismatch to ensure a proper function of the device!
Module Cable Interconnection
The cable is included in every extending module delivery. Both its ends are the
same. Configuration is 1:1. Connectors cannot be shifted or inserted conversely
because they are equipped with a so-called key.
The basic unit is always on the left. Extenders are chain-connected, i.e. each is
linked with its neighbour.
The cable cannot be driven through the box interconnecting holes until the boxes
have been connected (see subsection 2.3 Mounting – Mechanical Installation).
