CONNECTING AUXILIARY PERIPHERALS VIA SMARTWIRE
The SMARTWIRE terminal on the back of the M2000 is a multi-drop, RS485
communications interface. It may be used to network several Option boards
together in a “daisy chain” fashion.
WIRING FOR SMARTWIRE
SMARTWIRE terminal connections:
(V+) Positive SMARTWIRE power
(V-) Negative SMARTWIRE power
(A) RS485 differential + signal
(B) RS485 differential - signal
• The peripheral device being connected should have a terminal block with
the same signal names.
• Connections between the M2000 and the peripheral should be done using
a Beldon type 8723 cable or equivalent. The shield wire can be
connected to “V-“ terminal.
SMARTWIRE BRIDGE INTERFACE
Some available M2000 Option Boards utilize older technology and are not
SMARTWIRE compatible. The SMARTWIRE Bridge Interface board will be
included with these boards. If you have a 4-20 mA or Setpoint option board and
do not have a SMARTWIRE Bridge Interface, please contact the factory.
• A cable will be provided to connect TB1 on the SMARTWIRE Bridge
Interface board to the SMARTWIRE terminal on the M2000.
• Use the ribbon cable provided to connect the option boards to J1.
