Type	Wired (shielded twisted-pair cable)
Communications method	N:N token-bus method
Code	Manchester code
Modulation	Baseband code
Synchronization	Flag synchronization (conforms to HDLC frames)
Transmission path format	Multidrop method (bus type)
Transmission speed	The following are the maximum transmission distances depending on the transmission speed. 2 Mbits/s: 500 m 1 Mbits/s: 800 m 500 kbits/s: 1 km
Maximum distance between nodes	Not specified. (Maximum transmission distance must be satisfied for the entire system.)

*1. Discontinuation models in July 2012.
*2. With wired models, the maximum number of nodes is 32 if Repeater Units are not used. A Repeater Unit is required
when building a network with more than 32 nodes. If a Repeater Unit is used, be sure to use only the following
Controller Link Units or Boards and set the Wired Network 62 Node Enable Bit in the DM Parameter Area software
switches at all nodes.
CS1W-CLK23/CLK21-V1
CJ1W-CLK23/CLK21-V1
3G8F7-CLK23-E/CLK21-EV1
*3. CX-Net in CX-Programmer version 3.1 or earlier can be used only in a system with a maximum of 32 nodes (node
address 1 to 32). If a system is to be used with a maximum of 62 nodes (node addresses 1 to 62), use CX-Net in
CX-Programmer version 3.2 or higher or the CX-Integrator.
*4. CJ-series PLCs do not have a Link Area, but LR000 to LR199 are automatically converted CIO 1000 to CIO 1199.
