Preparing the Shield of RS-422A/485 Connectors
Always prepare RS-422A/485 cable shields properly. Otherwise, communications errors
may occur with the host.
Ground only one end of the shield when connecting the ground terminal (GR) of the de-
vices to the functional ground (FG: ), and grounding each signal line at only one point
and to 100
Ω
max, as shown in
Figure (a)
.
Ground both ends of the shield when not grounding the functional ground (FG: ) of the
PT, as shown in
Figure (b)
.
When using the CJ1W-CIF11 or when using the NT-AL001/NS-AL002 together with the
