2.3.2 M12 DeviceNet drop cables
For the use in for example the IN-FLOW range or CORI-FLOW range (IP-65 applications) it is best to use DeviceNet Drop
cables assembled on both sides with male connector M12 – female connector M12 (5-pins for data and power-supply
connections).

In case of powering instruments or transporting data over longer distances Bronkhorst offers also special RS485
Modbus data cable, with lower voltage-drop. Bronkhorst can advise you when to use this special cable, but for most
cases the standard patch-cables will do well.
If more cables are used in one system, they have to be connected as a daisy-chain. This means that the total Modbus
system has only one begin and one end. For connecting instruments to the bus, Bronkhorst offers special drop-cables
which enable you to build a daisy chained network of Modbus modules.
