Chapter 4 Installation Procedure

4.4 Network Medium

The CC121 can be used for different types of network media. The next table shows the possible options. Note that ARCNET allows the usage of different cable types on the same network.

Network Medium Options
Medium Connector Type of Cable Medium Tranceiver
Coax BNC RG62A/U coax cable HYC9088 Hybrid
Twisted-pair RJ11 Telephone twisted-pair HYC9088 Hybrid (RS-485)

The type of medium that is used depends on the installed medium transceiver. When the HYC9088 medium transceiver is used, the selection between a coax or a twisted-pair medium is made by the proper installation of the network decoupling circuits.

The medium option is selected during the production phase of the module.
