Data Port Pinouts
TXD represents the Transmit Data line, and RXD is the Receive Data
line.
The pinouts for the data port are listed in Table 1.
The pin layouts (as viewed from the rear panel of the N - 560) are
illustrated in Figure 3. The conductive shell is connected to earth ground
when connected to a PC or printer.
