Applicable connector: 25-pin D-sub (female)

All of the Command inputs are active when low. In order to activate them, they must be brought to ground level for 50 ms or longer. The ONLINE Tally pin (17) becomes active when a play command is received from any of the following:

the ONLINE function of the RC-801 remote control unit
the RC-8 remote control unit,
play command issued to either the REMOTE (PARALLEL) or REMOTE (SERIAL) connector
a PS/2 keyboard

The RECORD Command (pin 6). If this command is received, the MD-801 enters Input Monitor mode. To start recording, the RECORD and PLAY Commands must be transmitted simultaneously (pins 6 and 11).

Tally indicators

The Tally pins of the REMOTE (PARALLEL) connector may be used to connect LEDs, etc. for visual remote indication of the status of the functions which are associated with these pins.

NOTE: The tally outputs are open collectors, with the maximum load current being 20 mA and the maximum voltage being 30 V. Take care not to overload these pins: the maximum supply current is 100 mA.

While the MD-801 is in input monitor mode, the RECORD Tally signal (pin 15) will provide a flashing tally light.

Fader start

Pin 8 is a special case. If this input is brought low (for more than 50 ms), playback starts. If it is brought back to the high state, playback stops. This makes it suitable for connection to any switching mechanism such as the fader start outputs on a mixing console, or an edit controller, which connect this pin to ground when active. Note that the Incremental Play function (see 3.10, "Incremental play") can be used to cue the start of the next track automatically when the fader play pin goes high (i.e. playback is stopped).
