NET Module DCC100-E - User Manual
To connect accessories (turnouts signals or other) please refer to the "layout" module
instructions.
1.5 M unting n the lay ut
The decoder must be not touch anything else during operation. In particular it CANNOT
come into contact with any metallic material.
For temporary installations it can be placed on a non-flammable insulating surface
(plastic glass ceramic floor etc...).
For fixed installation it is recommended to mount it by screwing the HP-100 on a
wooden surface with the screws and spacers provided. This should be done before
inserting the DCC-100 (if additional modules have already been inserted they can be
removed gently without worries).
1.6 N rmal perati n f the DCC dec der
After connecting everything as
described activate the DCC signal
with the controller. Green LEDs 1 and
2 will light up indicating that the
connections are correct and the
decoder is on. (figure 2).
According to DCC-NMRA the
accessories can be addressed in two ways:
a) Decoder address. Each decoder has its own address and drives 4 accessories each of
which has two states (A and B). The accessories are identified by the address of the
decoder and by the position (1-4) relative to that decoder. So for example an accessory
is located in position 2 of the decoder with address 1 and another accessory can be found
in position 2 of the decoder with address 5.
If you use this configuration the default addresses are "1" for Layout Module 1 and "2"
for Layout Module 2.
b) Addressing by accessory: each individual accessory has its own address and
no address is assigned to the decoder. For
example if an accessory on a decoder has
address 2 no other accessory can have that
address even on other decoders.
In this case the default addresses are 1 to 4 for the layout module "1" and 5 to 8 for the
layout module "2".
The choice between the two modes depends on the settings of the digital control unit.
The decoder responds indifferently to both situations.
To change the addresses simply follow the procedure indicated in the chapter 2 of this
manual.
To operate the accessories please use the controls on your digital control unit.
In questo caso gli indirizzi di default sono da 1 a 4 per la scheda layout "1" e da 5 a 8 per
la scheda layout "2".
2. PROGRAMMING OF THE DECODER
2.1 Pr gramming c nnecti ns
The Helvest decoder can be programmed in any of the modes available in the DCC
control units: (by CV by page or by register).
The procedure for programming the decoder is as follows:
- Mount the DCC100-E module on the HP100 board as for normal operation.
- Connect the power wires to the HP100 board.
- Connect the programming wires to the DCC100-E board. In some control units these
come from the same output used for power supply while other control units have a
separated output for a programming track. In this case the HP100 board must be
connected to the programming track output.
- Disconnect any layout modules installed.
This operation is necessary only for some digital control units because of the low power
that they provide in programming mode. Leaving the layout modules connected the
decoder is programmed correctly even if the control unit signals an error. It is advisable
to remove them to confirm that programming has taken place and to read the CVs
correctly.
- Program the decoder according to the procedure provided for any locomotive or
accessory decoder. The programming procedure depends on your central unit.
- The system also allows you to read the CV values and have an acknowledgement of
programming without any additional connection and without the need to connect
anything to the outputs.
- The flashing of LED no. 3 on the DCC100-E module (fig. 2) means that it is responding
to the control unit during programming.
