NEW: Controlling Charlieplex signals with the OC32
It will soon be possible to control signals constructed according to the Charlieplex
principle with the OC32/NG. These signals are also offered
under the name “multiplex technology”.
The maximum of 12 LEDs in the signal are connected according to a matrix and the whole unit
is controlled with 4 wires. This technique is especially interesting for signals that
have many LEDs, such as the well-known German exit signal with distant signal (10 LEDs).
To be able to control these signals, an OC32-ADM/CPX
module has been developed for the OC32/NG. This module occupies 8 connections on the OC32 and controls
a maximum of 2 Charlieplex signals.
The OC32-ADM/CPX is supplied including a CPX-CM connection module. You
connect the connection module to the OC32/NG using 8 wires, and you can connect 2 signals to the
connection module that are equipped with a 4-pin square
plug, such as those used by Viessmann®, among others.
CPX-CM is also available separately in case you want to connect two signals
that are too far apart to plug them together into one connection module.
The ADM/CPX has an extensive set of functions with which signals
can be controlled realistically, with a lifelike transition
between signal aspects and with or without fading in and out. Especially for e.g. the Ks
signals, the module also features flashing functions. The speed of fading in and out,
the pace of transition between signal aspects and flashing frequencies are adjustable.
The exact introduction date is not yet final, but the OC32-ADM/CPX
and CPX-CM are expected to be available from early April 2026. The
recommended retail price for the OC32-ADM/CPX + CPX-CM set is €24.50
The new firmware for the OC32 version 3.22 as well as an update file for
OCConfig version 3.22 is now available on the downloads page.

DTRv2/PAR becomes DPS1X8
The DTRv2 is a relay module from the DinaSys portfolio to cost-effectively provide tracks at a
turntable with track voltage in a block-controlled
system. The DTRv2 is controlled via a CAN connection.
The DTRv2 also has a parallel version, where the control takes place from
for example an OC32 module. You then use this DTRv2/PAR, for example, to
provide multiple tracks of a staging yard with track voltage from just one
block output of a TM44, without having to connect a
tangle of wires.
DTRv2/PAR is now being replaced by the DPS1X8. It is actually the same module,
with the same handy connection options, but more compact and cheaper to
produce. DPS1X8 stands for “Double Pole Selection of 1 out of 8”.
Due to the more economical production, the DPS1X8 also gets a lower retail price than
the DTRv2/PAR, but that’s not all: We are also going to supply this module in the
form of a kit. This kit consists of a PCB already pre-assembled with SMD
components and loose Through-Hole components that the customer can
solder on themselves. These loose components are the relays and connectors, so it
(almost) can’t go wrong!
The recommended retail price for the DPS1X8 is €49.95
The recommended retail price for the DPS1X8 kit is €41.95
The DPS1X8 is available from late March 2026.

DPCO4 Kits
The DPCO4 is a relay module, intended to be able to switch all sorts of things
that need a galvanic connection. You can think of powering
routes by means of relays in a Dinamo system, frog polarization of
turnouts and crossings, etc. DPCO stands for “Double Pole Change Over”.
The DPCO comes in two versions: a version
DPCO4/05 where the relay control is powered with 7..15V and a
version DPCO4/12 for 13..24V.
In consultation with DinamoBesturing, we have decided to also start supplying these modules
in the form of a kit. This kit consists of a PCB already pre-assembled with
SMD components and loose Through-Hole components that the
customer can solder on themselves. These loose components are the relays and connectors,
so it (almost) can’t go wrong!
The recommended retail prices for the DPCO4 are:
DPCO4/05 Module: €34.95
DPCO4/12 Module: €34.95
DPCO4/05 Kit: €28.95
DPCO4/12 Kit: €28.95
