ZyXEL MODEMS AND AMIGA
You may connect any of the external models of the ZyXEL 2864 series to an Amiga
computer. The default modem settings should work fine in most instances.
Cable
Among the Amiga computers, two versions of the serial port exist. The Amiga 1000
has a female 25-pin connector, the other models a male 25-pin connector.
Use standard serial cables with 9 wires. For the models with a female connector, you
need a gender changer to fit the plug into the socket. Under no circumstances
should any other pin be connected than those described in the table below. De-
pending on the model of your Amiga computer, you may damage your modem if
other pins are connected! Some Amiga models carry non-standard voltages on their
connectors.
