VESDA ECO Detector by Xtralis

Installation

By default, the Modbus protocol settings for an RS485 interface are 

•

  Baudrate 19200 

•

  Parity Even 

•

  Stop Bits 1 

 

These are the default settings programmed into the ECO at shipping.  Refer to the 
ECO  Configuration  section  on  page  33  for  details  of  how  to  program  the  address, 
Baudrate etc. 

The RS485 specification gives a maximum permitted cable length of 1200m.  There 
are two methods of terminating the Bus.  The ECO detector can operate with either 
method, but the user should ensure that any 3

rd

 party devices attached to the bus 

are compatible with that method of termination. 

•

  Basic  DC  termination  in  which  a  120

Ω

  termination  resistor  should  be 

connected across the connections A & B at the two end points of the Cable, 
i.e. at the RS485 Master interface device and at the last device on the bus.  
The  ECO  detector  is  provided  with  a  120

Ω

  termination  resistor  fitted  to  the 

PCB assembly along with a jumper connection next to SKT2, which permits 
the user to connect the 120

Ω

 termination to the bus.  The jumper is fitted 

as  supplied  and  should  be  removed  from  all  units  except  for  the  last 
one in the line. 

•

  Biased  Bus  Termination.    Using  a  biased  bus,  the  user  must  use  an  AC 

termination  and  Biasing  resistors.  Refer  to  the  Modbus  specification  for 
details. 

The two methods of termination must not be mixed on the same bus.
