Cable Diagrams
Before using the following cable diagrams refer to the tables above to select the correct cable
for your application. Sometimes, crossover cables are wired slightly differently depending on
the application. A “complete” crossover cable would connect the TxD with RxD, DTR with
DCD/DSR, and RTS with CTS across both sides. A “simplified” crossover cable would cross
TxD and RxD and locally short-circuit DTR with DCD/DSR and RTS with CTS.
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 detec-
tion on their side. Both ends should have the same configuration for better use of the com-
plete version of the cables.
These cables appear in Cable Package #1 and/or Cable Package #2. You may or may not
find them in your box depending on which package you received.
