1. If your PC is fitted with a DB25 connector, use the same DB25 pinouts as for
modems, shown in
2. We assume you are connecting your PC directly to the Black Box device (no
structured cabling system).
3. In addition to the signals shown in the examples above, you may connect
Protective Ground (P/GND) if you have shielded twisted-pair (STP) cable.
Connect P/GND at either your equipment or the Black Box device (but not both).
P/GND will reduce interference in noisy environments.
4. The application of the connection example is a PC running terminal emulation
software set to 'hardware flow control'.
