Cautions on installing Ethernet transmission lines
When installing Ethernet cables, be careful with the following.
Connection type of the item to be used
Figure 2.10 is an example of connection of items that make up the Ethernet transmission system.
Install a cable clamp to the D-sub connector of each PCS-DS51 main processor unit.

Usage standard of cables
Typically, the main processor unit and transceiver of PCS-DS51 are wired by using AUI cables.
10BASE5 coaxial cables are used for connections between PCS-DS51 cabinets in the same
building, as well as between operator rooms. 10BASE5 coaxial cable connects the transceivers,
and it cannot be directly connected to the main processor module or Ethernet board.
For the wiring route of 10BASE5 coaxial cables, refer to “External Wiring”.
Use optical cables for cable wiring between different buildings. When optical cables are used, an
optical repeater converts the electric signal to optical signal, and vise versa.
