Programming On The Programming Track - Viessmann 4701 Bedienungsanleitung

4.5 Programming on the programming track

The configuration of the signal can also be accomplished by connecting it directly to the programming
output of the command station. Simply connect the terminals of the decoder to the programming output of
the command station as shown in fig. 7.
The signal address is programmed in 2 CVs. In CV 1 you set the lower byte (LSB) of the address, in CV
9 the upper byte (MSB).
Please note that signals with two uncoupled semaphore arms require two addresses.
The address is established as described below. Write the address value directly into CV 1 if you want to
assign an address between 1 and 255. Set CV 9 to 0. Addresses higher than 255 must be split into the
MSB and the LSB: Divide the desired address by 256 and determine the result without decimal points as
well as the remainder. The table on page 20 contains examples.
Further programming options are listed in the CV table. You may also set the desired digital protocol in
CV 40.
The decoder will respond to commands of the programming output of a DCC compatible command station
regardless of the set protocol.
Please note that due to the low current draw some command stations may not be able to read out data on
their programming output. Read chapter 9.5 for potential remedies.
Note:
If the switching direction is inverted caused by the properties of your DCC/MM command station you
can correct this according to fig. 8.1 or change by programming the CV 36 on value 1.
4.6 Configuration with Motorola central units
To use the signal in a digital environment, you have to assign a digital address at first. To control the signal
with a Motorola system, observe the following instructions:
1. Switch off the digital system (e. g. emergency off). There must not be any current at the rails.
2. Connect only the blue wire with the green marker and the power supply wires of the signal (brown and
yellow, fig. 7) to the rails – just 3 cables!
3. Switch on the digital system.
4. Connect the so far open second blue wire (red marker) to the track signal, too (fig. 7).
5. Use the digital command station to send a switching request for the desired Motorola address. The
signal receives the request, registers the address as its own and as a receipt, it switches the signal.
The decoder is now ready to be used with the new digital address. If you want to change the address, you
just have to repeat the described procedure.
Disconnect the blue wires from the track and insulate the ends.(fig. 8).
Note: If you use a multi protocol digital command station, which is able to use the Motorola as well as the
DCC system simultaneously, it is recommended to programme the signal on a DCC address.
4.7 Programming with POM
The decoder supports programming of all CVs via POM ("Programming on the Main"). Since not all
command stations support POM for switching decoders you may also set the decoder to respond to
the locomotive POM mode. Enter the value 80 in CV 8 of the address 9999. Then the signal decoder
responds to normal POM commands for locomotives under the respective address.
Please be careful to avoid inadvertent programming of other locomotives with the same address. Remove
locomotives with the same address from the track or disconnect power to such track sections. If RailCom
is active the corresponding feedback will be sent to the command station.
4.8 Switching outputs
The switching outputs can be configured to suit various functionalities (CV 38). The outputs are intended
for relays, but can also power small loads such as LEDs.
4.9 Feedback via relays
The signal is equipped with 2 transistor-driven outputs, which are able to indicate the aspect of the signal.
