ModBus Resources
ModBus is a public protocol that can be freely adopted by any developer or
manufacturer desiring to implement it. While a detailed discussion of
ModBus protocol is beyond the scope of this manual, there are a number of
up-to-date resources available on the internet for those wishing to
investigate ModBus further. The most complete resource is
www.modbus.org.
Termination
When putting devices on the ModBus network, a terminating resistor may be
required for the last device on the network (please see www.modbus.org for
more details). The has a blue jumper on the “public” jumper
that can be used to jumper in a 120-Ohm terminating resistor. By default,
this jumper is not in place. Industrial Scientific - Oldham does not
recommend changing the placement of any of the other jumpers on this
board.
