Tascam HD-R1 User Manual

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

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

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.
