For buses whose length is greater than 5000 m, the use of repeater type systems may be necessary to ensure the
quality of transmissions.
(2)
The network speed is set by the PROFIBUS master. eNod4 PRO DIN performs self-adjustment.

Type A cable: AWG 22, impedance: 135 to 165Ω.
(3)
Type B cable: AWG 24, impedance 100 to 130Ω.
5.1.2 PC communication
Both models: eNod4 DIN and eNod4 PRO DIN can communicate with a PC using the protocols ModBus RTU or SCMbus
through the USB connector accessible from the front panel.
The appropriate USB driver can be downloaded from our website: http:// www.scaime.com, it is also available on CD to
order from our sales department.
 Note: If eNodView software has been correctly installed, it is not necessary to re-install the USB drivers when
connecting another eNod4 on the same USB port (Windows only asks for the driver if the device is connected
to another USB port).
5.1.3 AUX Communication (for HMI)
AUX eNodTouch HMI must be connected through connector AUX (A4). The common mode voltage admitted is  27VDC
from GND power supply.
When eNod4 is positioned at the end of the line the 150 Ω integrated resistor can be used (connecting jumper).
5.2 Communication address selection
Rotary switches selection (SW1 and SW2) accessible from the front panel. The new address only is taken into account
after a reset.
