WIRING TO A COMPUTER

The DB-9 connector labeled "PC" connects the Eclipse-32 matrix to an external
computer. This connector is located on the Eclipse-32 matrix's front panel.
To connect a computer to the matrix, run cable from the matrix's "PC"
connector to the PC's serial port. The maximum recommended length of the
cable is approximately 10 feet (3 meters).
A computer has either a 9-pin serial port or a 25-pin serial port. Figure 13 shows
the wiring for a 9-pin port. Figure 14 shows the wiring for a 25-pin port.
