CHAPTER 3: Installation

The four switched ports, A through D, are wired DCE (output data on pin 3, RD). The master port is wired as DTE. To directly connect a terminal device to the master port, you need a null-modem cable (see Figure 3-2).

Control leads required vary from device to device. Consult your device’s operations manual for details on your specific needs.
