See 1-2-6 Devices Required for Connection for details on available H-PCF
Optical Fiber Cables.
1. Always use the specified Optical Fiber Cables.
2. The maximum distance between nodes depends on how the cable is pro-
cessed. For details, refer to the applicable Optical Fiber Cable (H-PCF)
manual.
All of the nodes in the network (including standby Units) are connected in a
ring with H-PCF Optical Fiber Cable.
The nodes can be connected in any order, but be sure to begin with the upper
connector (SL1) of the highest node in the network and connect to the lower
connector (SL2) in the next lower node, as shown in the following diagram.
Although there is no fixed order in which the nodes must be connected, in
order to minimize the effect on communications time in the event of a discon-
nection, it is recommended that they be connected in order of node address
(node 1 → node 2... → node 62 whenever possible).
Pairs of Controller Link Units used in duplex operation can also be connected
in any order but they must be connected with special cable. (There must be no
other nodes between them.)

1. Connect active and standby Controller Link Units using either the CS1D-
CN051 Duplex Unit Connecting Cable or an Optical Fiber Cable with a con-
nector (S3200-CN@@@-@@-@@). See 1-2-6 Devices Required for Con-
nection for details on available H-PCF Optical Fiber Cables.
2. Always use the specified Optical Fiber Cables.
