TASCAM HD-R1
5–Parallel Interface
The parallel port (25-pin D-sub connector on the rear
panel) can be used to remotely control the HD-R1’s
playback using logic signals. By default, the input
signals are active low (normally high). Each input pin
has a built-in 10 kΩ pull-up resistor to 3.3V. Closing
a switch between an input pin and ground (pins 23
and 24) normally activates that input by pulling
it low. If needed, the polarity of the input signals
can be changed using
Main Menu ˘ System
Settings ˘ Parallel Port ˘ Input

.
The HD-R1’s busy status is communicated using
internal, solid-state relays to make or break a
connection between two pins on the parallel port.
There are two busy relays. They can be configured as
normally-open or normally-closed, and may indicate
a variety of conditions depending on the settings
found at

. These include indicating when

A switch connection applied between pin 17 and
ground (pins 23 and 24) is equivalent to pressing the
STOP
key with the default “Active Low” parallel port
polarity.
External play has three modes:
Direct Play
,
Binary Play
, and
Program Play
. This
mode is set using

signals differently.
