TASCAM DS-M7.1
Making up a remote control cable
It is possible to make two kinds of remote control
cable, allowing the front panel of the DS-M7.1 to be
detached and used as a remote control unit.
The first type may be up to 5 m (about 15 feet) long
(standard cable), and may use a general-purpose
cable.
The second type (extended) allows remote control up
to 20 m (over 65 feet) away, and must be constructed
using a specially-specified cable (described here).
No guarantee of correct operation can be given if a
cable over 20 m, or a cable which is not constructed
according to the guidelines here, is used to connect
the remote control unit to the main unit.
Standard cable
In this case, a standard RS-232C extension cable of
up to 5 m in length may be purchased from a com-
puter supply outlet and used.
This cable should be a “straight” shielded cable, with
a male 9-pin D-sub connector on one end, and a
female 9-pin D-sub connector on the other. The wir-
ing should be straight through, with 1 connected to 1,
2 to 2, etc. through to 9 to 9.
Note that cables sold for extension purposes are usu-
ally fitted with male and female connectors, and for
that reason, we recommend the use of these cables.
Extended cable
This cable must be made specially, using a cable with
the following specifications:
Shielded twisted-pair cable of at least 22AWG
should be used, with a length of 20 m or less.
A male 9-pin D-sub connector should be attached at
one end, and a female 9-pin D-sub connector at the
other.
Pin connections should be made straight through: 1
to 1, 2 to 2, through to 9 to 9.
All pins (and frame ground) should be connected.
