Figure 5-33 Terminal wiring
2) Method 1: Check whether other terminals of the node share a reference ground with the 485 circuit.
If yes
,
connect the CGND cable (shield layer) of the bus to the corresponding pin;
3) Method 2: Find the reference ground of the 485 circuit on the board of the node and connect a cable
from the reference ground to CGND or the shield layer;
4) Method 3: If you cannot 󶍾nd the reference ground of the 485 circuit
,
keep the CGND cable or shield
layer unconnected
,
as shown in the preceding 󶍾gure
,
and use an additional ground cable to connect
the node to the PE terminal of other nodes.

Transmission distance and number of nodes
The maximum node count and transmission distance supported by the standard 485 circuit at di󶍽erent
transmission rates are as follows:
No. Transmission Rate Transmission Distance Number of Nodes Cable Diameter
1 115.2 kbps 100 m 128 AWG26
2 19.2 kbps 1000 m 128 AWG26
5) Communication port introduction
As shown in the following 󶍾gure
,
CN1 is the RS485 port
,
which supports two channels of RS485 ports.
The two RS485 channels share a DB9 interface. The signal arrangement is as follows:
