Wiring for a CompoNet Network
Section E-3
E-3-5 Connecting Nodes
This section explains the procedures to connect Units that compose a
CompoNet network. Below is the representative case of connecting the
Master Board and cables.
Connecting the
Master Board
The Master Board must be connected and located at the end of the
trunk line, unless the network uses the unrestricted wiring formation.
The Master Board is connected with the communications cable via the
communications connector provided on the Master Board. Cable
connectors differ by the type of cable used as the communications
cable.
When Using Round
Cable I or II with Open
Type Connectors
Use a DCN4-TB4 Open Type Connector to connect a round cable I or II to the
Master Board. The Open Type Connector converts the communications
connector of the Master Board to a terminal block. The terminal block for this
purpose must have M3 crimp terminals.
