1. GENERAL PRODUCT PRESENTATION
1.1 What is the Helvest Flex system?
The Helvest Flex system is designed to easily assemble electronic circuits for the
control of a model railroad. Decoders can be made to manage switches, signals and
other accessories, presence detectors, and other future developments.
The HP100 motherboard is the heart of the system. It manages a maximum of three
modules, automatically identifying them and activating their specific functions.
There are two types of modules:
- “net” module: it communicates with other units, with the digital control unit or with
the PC (e.g. it manages the DCC digital signal to control the switches, or
communication buses to report the presence of trains).
- “Layout" module: manages the devices present on the layout (for example it moves
the switches or receives the data from the sensors that detect the presence
of the trains).
The main advantages of the system are:
- You can configure it according to your needs by combining the additional modules
as you wish.
- It is extremely easy to make changes, modifications or updates to the modules.
- You can expand it with new modules that will be available in the future.

OPERATIONS
2.1 Mounting the board
The complete board must be mounted in such a way that it DOES NOT
touch anything during operation. In particular, it
must not come into contact with any metallic or
flammable materials.
For temporary installations, it can be placed on a
non-flammable insulating surface (plastic, glass,
ceramic floor, etc...).
For fixed layouts, it is recommended to mount it by
screwing the HP-100 onto the wooden structure with
the screws and spacers provided (fig. 3). This
operation must be done before inserting the
additional modules.
2.2 Installing the additional modules
The installation of the additional modules must be carried out with the power supply
switched off.
