Connecting the I/O Link

Figure 9.7 shows I/O link connections to a direct communication module
(1771-DCM) both as a middle device and as an end device on a link. The
clear-insulation conductor connects to the top terminal. The
blue-insulation conductor connects to the bottom terminal. At each direct
communication module, connect the shield drain wire of each cable
segment to give the shield continuity. However, never ground the shield at
a direct communication module. At a direct communication module
connected as an end device on a link, connect a 150-Ohm 1/4-Watt
termination resistor across the signal lines.

ATTENTION: Do not disconnect the connector on a middle
device when the system is operating because that would cause
discontinuity in the link and remove the termination.
The connection between terminals is inside the module.
Figure 9.8 shows I/O link connections to a 2705 RediPANEL module both
as a middle device and as an end device on a link. The blue-insulation
conductor connects to the top terminal. The clear-insulation conductor
connects to the bottom terminal. At each RediPANEL module, connect the
shield drain wire of each cable segment to give the shield continuity.
However, never ground the shield at a RediPANEL module. At a
RediPANEL module connected as an end device on a link, connect a
150-Ohm 1/4-Watt termination resistor across the signal lines.
