Do not exceed the maximum current for the wiring
Determine the maximum possible current for each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current exceeds the maximum rating, the wiring could overheat, causing serious damage to
your equipment.
Grounding the ioLogik R2140
The ioLogik R2140 is equipped with two grounding points, one on the wall mount hole and the other
on the DIN-rail mount.
Setting the RS-485 Baudrate
The RS-485 port on the ioLogik R2140 is reserved to chain another RS-485 I/O server. The RS-485
port can run Modbus/RTU or I/O command sets. The baudrate is set by a physical dial on the back of
the ioLogik R2140. The default settings are baudrate = 115200, parity check = N, data bits = 8, and
stop bit = 1.
