Cyclades-TS Installation Manual
Most of the diagrams in this document show the “complete” version of the crossover cables, with support for
modem control signals and hardware flow control. Applications that do not require such features have just to
configure NO hardware flow control and NO DCD detection on their side. Both ends should have the same
configuration for better use of the complete version of the cables.
Cable #1: Cyclades RJ-45 to DB-25 Male, Straight Through
Application: It connects Cyclades products (serial ports) to modems and other DCE RS-232 devices.
