Rail-Switch II User Guide
The diagram below shows how Rail-Switch II could be utilised in a typical application. The DMX
controller is not required if the Rail-Switch II has been preset programmed using RDM, or if it
is in test mode.

It is recommended that inline current-limiting
filters (e.g. Sequence-Filter) are used to protect
the relays in Rail-Switch II for all inductive loads.
Data loss mode
DMX-Workshop (or a suitable RDM tool) also
allows programming of data loss mode. This
mode is intended to be used when Rail-Switch
II is being controlled by DMX (i.e. when it is
not running in preset mode).
The data loss programming determines what
Rail-Switch II should do if DMX is lost for
more than 2.5 seconds. It can be selected to
play one of the 8 presets or hold the last state.
If DMX returns, the control is immediately
returned. Rail-Switch II will also power up in
this mode until DMX is detected.
To access the data loss mode menu, right-
click the Rail-Switch II RDM device, then go
to Advanced - Artistic Licence products - Data
loss mode.
The priority of output is as follows (highest at
the top):
1.
Test pattern
2.
Preset playback
3.
Data loss event
4.
DMX512
Test mode
Output priority
Rail-Switch II offer two test patterns:
Test 1 = all outputs on
Test 2 = all outputs off
DMX-Workshop (or suitable RDM tool) can be
used to put the product in test mode, which
can be useful during show commissioning or
rehearsals.
To access the data test mode selections,
right-click the Rail-Switch II RDM device, then
go to ‘Self test’.
Preset playback is non-volatile. This means
that if a preset is played back, Rail-Switch
II can be then disconnected from DMX and
power cycled and will still playback the preset.
