Using the SRC8 with
DCC Specialties products
The SRC8 provides a very cost
effective solution for a LocoNet interface. There are
eight groups of throw/close inputs for turnout control
and reporting. Optionally, these can provide up to 16
inputs for sensor state reporting. The group inputs can
be individual programmed to any of these three types
inputs.
Typically the SRC8 group inputs connected to the
Hare and Wabbit would be programmed for turnout
(switch position reporting) feedback and for the PSX
and PSX-AR series as sensor (version 50 or later of
the SRC8). Because of the SRC8 flexibility you can
have Hares, Wabbits and PSXs all connected the SRC8
inputs at once.
Below is a diagram showing how each of the DCC
Specialties products can be connected to the SRC8. For
details on how to program the SRC8 look at the manual
located on this page.
Below is a diagram showing
how eight Hare can be connected to a SRC8. The optional
TSA provides the connivence of screw
terminals. All group inputs would be programmed for
turnout (switch position reporting) feedback.
A typical application is
depicted below where a SRC8 receives status information
from several DCC Specialties products and transmits it
over LoconNet to a SIC24. The SIC24 is used to drive
LEDs on a panel to visibly show the status. A TSA is
used to provide screw terminals for the wires
connected to the SIC24. It also provides the current
limiting resistors for the LEDs used on the panel.
TSAs could be used with the SRC8 as shown above. In
this example the panel would show turnout status from
the Hare and block occupancy and short circuit state
from the PSX. This scheme greatly reduces the length
of individual wires and reduces the complexity of the
wiring.
