MODULAR SMART SWITCH

A.5 Connecting to Plotters

A wide range of different pin configurations are used on plotter serial ports. The following cable can be used for most plotters including those manufactured by Hewlett Packard and Roland. Notable exceptions are Calcomp plotters, which need a “straight-through” cable shown in Figure A-4. If you have a cable that currently works between your PC and plotter, then this can be used between the Modular Smart Switch and your plotter with the addition of an adapter.

A.6 Connecting to NEC Spinwriter

The NEC Spinwriter® series of printers also provide a DB25 socket connector for serial data. However, their “printer ready” flow-control signal is output on pin 19 (unlike most printers, which output this signal on pin 20). Suitable wiring is as shown in Figure A-6.
