The
ICF-1150 series supports 2 serial ports, with a D-sub connector
for RS-232 communication and a removable terminal block
for RS-422 or RS-485 communication. The 3 ports (2 serial
ports and one fiber port) are completely independent.
When an ICF-1150 converter receives data from any one
port, it will send the data out through the other 2 ports.
For example, once the ICF-1150 converter receives a command
from the remote master through the fiber port, it will
convert the signal and send the command through the RS-232
and RS-422/485 ports at the same time. If the user is
monitoring a system running on an RS-485 network, there
is no need to use an additional RS-232 to RS-485 converter
to connect the laptop computer's serial port to the RS-485
bus.
Rotary
Switch for Setting the Pull High/Low Resistor
The
RS-485 interface supports multi-drop or daisy-chain connections,
which system engineers will use to connect serial devices
such as meters, RTUs, and readers together on the same
bus. Since the number of serial devices on the same bus
will cause the impedance of the data line to increase,
the ICF-1150 allows users to tune the pull high/low resistor
by simply rotating the switch to the appropriate value without
removing the ICF-1150 from the DIN-rail.
