Serial Network
The system uses screw terminal for RS-485 twisted pair connection as a
data gateway between Ethernet Sever and serial Modbus devices. See
Figure 2-3. The following information must be considered.
1. Twisted-pair wire compliant with EIA-422 or EIA-485 standards, which
contains 24 AWG thin copper conductor with copper mesh and alumi-
num foil for shielding.
2. Always use a continuous length of wire, do not combine wires to
attain needed length.
3. Use the shortest possible wire length.
4. Use the wire trays for routing where possible.
5. Avoid running wires near high energy wiring.
6. To reduce electrical noise, it should be twisted as tightly as possible.
