ioLogik R1200 Series
Initial Setup
2-6
Jumper Settings (DIO and AI)
The models with DIO or AI channels require configuring the jumpers inside the cover. Remove the screw
located on the back panel and open the cover to configure the jumpers.
DIO mode configuration is shown to the right (default: DO Mode).
Analog mode configuration is shown to the right (default: Voltage Mode).
ATTENTION
Remove the screw on the back panel and open the cover to configure the jumpers.
Pull High/Low DIP Switch Settings for the RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection of serial
signals. When using termination resistors, it is important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. Since there is no resistor value that works for every environment, DIP
switches are used to set the pull high/low resistor valve for each RS-485 port.
