The SnakeSys R4 is a multi-purpose network distribution node, comprising DMX
output ports, DMX input ports and multiple network ports in a 1U rack.
The SnakeSys R4 is designed to be used on stage for Ethernet to DMX
conversion, at front of house for DMX to Ethernet conversaion, and in any other
location that requires conversion between DMX and Ethernet or Ethernet
Using one SnakeSys R4 at front of house and one SnakeSys R4 at stage
interconnected by a single CAT 5 network cable, the system provides four DMX
lines and three independant network lines all over one cable.
The SnakeSys R4 is a 1U rack featuring:
- Powercon input
- UPS battery backup
- Three Ethercon network connections on front (all can supply Power over
- Two Ethercon network connections on rear
- Four 5-pin DMX output sockets on the front
- Four 5-pin DMX input sockets on the rear
- Full break detect on all four DMX inputs
- Two remote contact inputs
- Relays to automatically connect inputs to outputs in the event of a power

The front panel provides simple configuration using easy to operate
switches. The configuration of the unit can be immediately determined
throught the front panel status LEDs.

Physical enable/disable switch for the DMX section
The SnakeSys R4 stores the current state of all swtches and the internal
configuration, so if it is powered down or restarted it will restart in the same
On the front panel there are 4 selection switches for enabling and disabling
each of the three front network ports and the DMX sub-section. Each of the four
switches has a status LED to indicate enabled or disabled.
The enable/disable switches for the network ports enable multiple lighting
consoles or other equipment to be connected to the switch and to be physically
switched in or out of the network. Traditionally this has been carried out by
physically unplugging network cables, however this is prone to error with cables
getting lost or damaged. When a network port is disabled, the transmit and
receive on that network port is disabled at software level, but the physical
connection is maintained and the LEDs continue to show the presence of a
physical link. This avoids delays when the port is re-enabled.
The DMX switch enables the DMX input rather than the network input.
When the interface is operating as an Ethernet to DMX convertor in output
mode, the DMX control switch freezes the current state of the DMX output.
The DMX outputs are connected to the DMX inputs via relays. If the unit loses
power then the inputs will automatically connect to the outputs so that the unit
is bypassed. This allows mutiple units to be used giving a level of redundancy
which is normally only available by using DMX switchers.
It is also possible to bypass the unit using the front panel bypass switch,
or from MagicQ when in ChamNet mode.
VLAN operation is selected from a switch on the front panel, or when in
ChamNet mode from MagicQ. To operate the VLAN you need a SnakeSys R4 at each
end, and the VLAN switch set on both.
In VLAN mode, each of the network ports on the front panel operate
independantly of each other, providing a virtual network between the two
SnakeSys R4 interfaces. Network traffic on port 1 at one end will only be
transferred to port 1 on the other end, port 2 to port 2 and port 3 to port
The overall bandwidth of the CAT 5 cable between the SnakeSys R4 units is
shared between all three ports with no single port being able to hog the
network. In VLAN mode, the DMX section on each box is connnected together - one
box is set as input and the other set as output which gives four DMX links
between the two boxes.
