RJ-45 Connectors
Twelve RJ-45 modular jacks on the rear panel (see Figures 2-5 to 2-7)
each support a single channel. Pinout for this option is given in
Appendix B.
The six-channel operation with full duplex data and transmitting control
signals end-to-end requires special cables (not provided by RAD).
Figure 2-11 shows suggested pin connections for transmitting a
DTR-to-DSR control signal and Figure 2-12 those for transmitting an
RTS-to-DCD control signal.
