Straight-Through Cable
When making a straight through cable, you will need some shielded cable with the
appropriate number of conductors within, a DB9 male plug (for the MAXPage end) and
either a DB9/DB25 male/female for the other end, depending on the equipment it is being
connected too.
The table below shows the pin-outs required for correct operation.

Null Modem Cable
When making a null modem cable, you will need some appropriate cable, a DB25 female
plug (for the MAXPage end) and either a DB9 female or DB25 female for the other end,
depending on the equipment it is being connected too. The table below shows the pin-outs
required for correct operation.

NOTE: Many serial connections require TX, RX and GND only. However some
devices, will use all of pins listed. If you are unsure then use all pins.
NOTE: It is important to note the gender required at each end of a serial cable before
acquiring or making a cable.
NOTE: The pin number is usually written next to the pin on the serial connectors
themselves in very small writing.

WARNING: Do NOT connect MAXPage to printer (or parallel) port output unless
you use a parallel to serial converter. A printer port looks similar to a DB25 serial port
but is female.
