Introduction  

The  DMX  splitters  of  the  ISP-­‐4  line  of  products  boost  an  incoming  DMX  signal  and  provide  it  on  four  output  ports.  

This  allows  for  connecting  more  than  the  32  devices  allowed  according  to  ANSI  E1.11  to  a  single  universe,  as  well  as   for  building  star  topologies.  Further  more,  the  ISP-­‐4  splitters  also  act  as  repeaters  and  may  thus  be  used  for   transporting  a  DMX  signal  across  larger  distances.  

DMX  signals  often  get  disturbed  by  the  environment  or  even  by  the  devices  connected  to  the  signal.  An  ISP-­‐4  splitter   may  completely  clear  the  disturbances  if  it’s  connected  at  a  location  where  the  signal  is  still  “readable”.  

Providing  four  individually  optically  isolated  outputs,  as  well  as  an  optically  isolated  input,  the  ISP-­‐4  splitters  may   prevent  harmful  voltages  applied  to  a  given  port  from  affecting  the  other  ports  and  damaging  the  connected   equipment.    

The  ISP-­‐4R  variants  work  within  DMX  /  RDM  environments,  as  well  as  in  pure  DMX  environments.  Therefore,  ISP-­‐4R   splitters  are  a  good  solution  not  only  for  current  RDM  users  but  also  for  those  who  expect  to  use  RDM  in  the  future.  

The  ISP-­‐4D  variants  on  the  other  hand  only  work  with  DMX,  while  they  ignore  any  RDM  data.  

ISP-­‐4  splitters  are  Din  rail  mountable  and  powered  by  an  external  power  supply  unit  (not  included).

Safety  Information  

Consider  the  following  notes  absolutely  when  you  set  up,  connect  and  use  the  ISP.  

This  product  is  not  for  household  use.  Read  this  manual  before  operating  the  device,  follow  the   safety  precautions  and  observe  all  warnings  in  this  manual.  

Use  this  device  only  in  accordance  with  local  laws  and  regulations.  

Safety  Precautions  

•

Disconnect  the  device  from  AC  power  before  removing  any  cover  or  part,  including  any   fuse  and  when  not  in  use.  

•

Ensure  that  the  device  is  electrically  connected  to  ground  (earth).  

•

Use  only  a  source  of  AC  power  that  complies  with  local  building  and  electrical  codes  and   has  both  overload  and  ground-­‐fault  (earth  fault)  protection.  

•

Before  using  the  device,  check  that  the  power  distribution  equipment  and  cables  are  in   perfect  condition  and  rated  for  the  current  required  of  all  connected  devices.  

•

Isolate  the  device  from  power  immediately  if  the  power  cable  or  the  power  plug  is  in  any   way  damaged,  defective  or  wet,  or  if  they  show  signs  of  overheating.  

•

Do  not  expose  the  device  to  rain  or  moisture.  

•

Do  not  operate  the  device  if  any  cover  or  component  is  missing,  damaged  or  deformed.  

•

Refer  any  service  operation  not  described  is  this  manual  to  Swisson.  

•

Provide  unrestricted  airflow  around  the  device.  

•

Do  not  operate  the  device  if  the  ambient  temperature  exceeds  55°C  (131°F).  

•

Do  not  modify  the  device  in  any  way  not  described  in  this  manual  or  install  other  than   genuine  Swisson  parts.  

•

Do  not  attempt  to  bypass  any  fuse.  Replace  any  defective  fuse  with  one  of  the  specified   type  and  rating  only.  

•

When  suspending  the  device,  ensure  that  the  supporting  structure  and  all  hardware  used   can  hold  at  least  10  times  the  weight  of  all  devices  suspended  from  them.  

•

When  suspending  the  device,  install  a  secondary  attachment  such  as  a  safety  cable  that  is   approved  by  an  official  body  such  as  TÜV  as  a  safety  attachment  for  the  total  weight  it   secures.  The  safety  cable  must  comply  with  EN  60598-­‐2-­‐17  Section  17.6.6  and  be  capable   of  bearing  a  static  suspended  load  10  times  the  weight  of  the  device.  

•

Make  sure  that  any  external  cover  and  rigging  hardware  is  securely  fastened.    

•

Block  access  below  the  work  area  whenever  installing,  servicing  or  moving  an  overhead   device.  

•

Do  not  use  the  device  in  areas  where  it  is  exposed  to  direct  sunlight.

PSU  Connection  

A  suitable  power  supply  unit  that  meets  the  following  conditions,  must  be  supplied  by  the  user:  

•

Stabilized  DC  output  voltage:  10V  –  48V,  max.  400  mA  

•

Power:  4  W  

See  page  7,  item  1,  “power  input”.  

It  is  not  strictly  required  but  highly  recommended  to  properly  connect  the  ground  pin  to  earth.  Not  connecting  the   ground  pin  may  affect  the  performance  of  the  device.  

The  device  can  only  be  operated  as  a  “ground  referenced”  transmitter  if  it  is  properly  grounded.  See  page  9.  

Warning!  For  protection  from  dangerous  electric  shocks,  the  device  must  be  grounded  (earthed).  The  local  AC   power  source  must  have  both  overload  and  ground-­‐fault  (earth  fault)  protection.  

 

DMX  Connections  

The  DMX  input  is  fully  isolated  and  has  a  built  in  termination.  

Depending  on  the  product  variant,  the  DMX  inputs  and  the  

DMX  outputs  are  provided  as  pluggable  screw  terminals  or  as  

RJ-­‐45  connectors.

The  DMX  standard  ANSI  E1.11  suggests  that  transmitters  are  “ground  referenced”.    With  the  ISP-­‐4,  this  is  achieved   for  each  output  port  by  wiring  pin  3  to  pin  4.    

 

In  some  cases,  however,  the  above  configuration  may  lead  to  so  called  ground  loops.  This  applies  when  a  DMX   receiver’s  COM  input  signal  is  connected  to  the  earth  with  a  low  resistance.    In  such  cases  it  may  resolve  issues  by   not  connecting  pin  3  to  pin  4  of  the  corresponding  output.    

 

Note:  Only  with  the  latter  setup,  each  output  port  is  individually  optically  isolated,  meaning  that  it  is  totally   isolated  from  the  other  output  ports  and  from  the  input  section.  

Models  with  RJ45  Connectors  

The  RJ45  versions  ISP-­‐4D-­‐DC-­‐RJ45A,  ISP-­‐4R-­‐DC-­‐RJ45A,  ISP-­‐4D-­‐DC-­‐RJ45B  and  ISP-­‐4R-­‐DC-­‐RJ45B  are  configured  as  

“isolated”  transmitters  as  defined  in  ANSI  E1.11,  such  that  each  output  port  is  individually  optically  isolated,  meaning   that  it  is  totally  isolated  from  the  other  output  ports  and  from  the  input  section.  

 

ANSIE1.11  compliant  RJ45  configuration,  applies  to  

ISP4X-­‐DC-­‐RJ45A  models.

Line  Termination  

The  line  termination  of  the  ISP-­‐4  splitters  may  be  turned  on  or  off  using  the  toggle  button  next  to  the  through  port.  

See  page  7.  The  line  termination  should  be  turned  on  by  pushing  it  down  when  no  receiver  is  connected  to  the   through  port  of  an  ISP-­‐4,  and  turned  off  otherwise.

A  missing  termination  at  the  end  of  a  DMX  chain  may  lead  to  significant  reflection  issues.  Additional  termination   resistors  in  the  middle  of  a  chain  may  cause  an  unwanted  drop  of  the  signal  level.  Line  termination  is  also  known  to   reduce  the  susceptibility  to  environmental  noise.  

 

RDM  Protocol  (Remote  Device  Management)  

All  ISP-­‐4R  models  support  the  RDM  protocol.  ISP-­‐4D  models  do  not  support  the  RDM  protocol.  The  ISP-­‐4R  models   forward  incoming  RDM  messages  to  all  connected  devices  and  send  the  RDM  responses  back  to  the  RDM  controller.  

The  ISP-­‐4R  acts  as  a  non-­‐proxy  inline  device.  Further,  the  ISP-­‐4R  is  a  responder  itself.  It  responds  to  RDM  messages   and  can  be  discovered  on  an  RDM  network.
