The model is designed to operate as a DTE (Data Terminal Equipment). When connecting
the Serial Port Adapter to a DCE (Data Communication Equipment), e.g. a modem, a regular
modem cable, straight cable, shall be used. When connecting the Serial Port Adapter to
another DTE, e.g. a PC, a crossover serial cable must be used. The crossover cable must have
TD and RD crossed (pins 2-3 and 3-2), RTS and CTS crossed (pins 7-8 and 8-7) and
optionally DTR and DSR crossed (pins 4-6 and 6-4).
