2.5 Extending Module Connection

®
2N Analog Vario 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 2N
connector (for connection of another, more 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).
