marked SH should be connected to the shield of the RS-485 network cable.  Do NOT connect the shield
to earth.

These three connections at this terminal block are optional and only needed when remotely accessing the
C-100MB through Modbus.

A  good  quality  twisted-pair  shielded  cable  should  be  used  for  the  RS-485  network.    The  cable  should
connect  to  each  device  on  the  network  in  a  daisy-chain  fashion.    Branch  lines  or  splits  are  not
recommended.  The maximum length of the cable should be 4,000 feet or 1,220 meters.

This port has built-in line biasing and termination.

3.2.4 External Start Input

The  External  Start  connection  (CN4)  is  a  two  wire  terminal  block  located  towards  the  left  of  the  printed
circuit board.  It is identified with CN4 and an open switch symbol.  These two terminal screws are polarity
independent  and  are  intended  only  for  a  dry  contact  closure,  such  as  a  relay  output  from  a  PLC  or  a
pushbutton switch.  This connection does not source or sink any negligible amount of current so a quality
twisted-pair cable of 20 to 22 AWG wiring is sufficient.  A shielded cable is not required; however, if one is
used leave the shield un-connected at the console.

The External Start connection is optional and only needed when a PLC/DCS or remote pushbutton switch
is  needed  to  initiate  a  measurement.    This  input  can  only  trigger  one  SmartBob  sensor  but  can  be
assigned to any one on the network.  This input is negative edge-triggered, meaning the dry contact must
be cycled open and then closed again to initiate a new measurement.
