The two options, purchasing your cable or making it, are covered next.
Purchase Your Serial Cable
To purchase your cable (from your local amateur radio dealer or computer dealer):
•
specify that you need a standard serial modem cable (RS232), with high quality
shielding (see Note 2 in the Radio Frequency Interference Statement section),
less than 3-m in length, and at least 5 wires connected.
•
Specify that one connector be a male DSUB-9 connector (to connect to your
MT1200’ female “Computer” port) and the other connector be a female DSUB-9
or DSUB-25 connector (depending upon whether your computer’s serial (COM)
port has a male DSUB-9 or male DSUB-25 connector)
Making a Serial Cable
This section is for those making your own cable instead of purchasing one.
We assume that if you are making your own cable you are familiar with the process and
just need to know: (1) what parts are needed, and (2) how the parts are connected.
Parts needed:
♦
a male DSUB-9 connector, to connect to the MT1200’ “Computer” port,
♦
either a female DSUB-9 or a female DSUB-25 connector, depending on the
connector on your computer’s serial (COM) port, to connect to the computer’s
(male) serial (COM) port,
♦
an appropriate length (less than 25’) of high quality shielded cable with 5 or more
wires,
•
as shown below, if you are using a DSUB-9 connector, either 5 or 8 wires can
be connected and any other wires are unused,
