6. Connecting the remote control panel
The removable remote control panel communicates with the recorder
over an RS422 9-pin Sub D connection and uses the same pinout as
Sony
© P2, also known as Sony 9-pin protocol.
In this communication standard pin 5 is not used, but is used by
bonsaiDRIVE for the 5 volt supply to the remote control panel. This
pin 5 on output C21 (bonsaiREMOTE) of the recorder is protected by
a PTC temperature element in the event of a short circuit.
Use the 5 meter long 9-pin Sub D cable supplied or any other 1:1
wired 9 Pin Sub D cable to connect the remote control panel to the
recorder.
RS 422 works with cable lengths up to 100 meters. If you already
have a 9 pin cable system installed or use 9 pin patch fields the
bonsaidrive control panel can be integrated and locally powered with
5 Volts on pin 5.
Attention! The DC input on pin 5 is not protected against reverse
polarity or overvoltage. Be certain that the auxiliary power supply
used is a 5 Volts regulated and can deliver at least 100 mA.
The remote panel can be connected or removed at any time from the
bonsaiDRIVE (also during record) without affecting the function of the
recorder.
At every reconnection the panel does a LED test in which the LEDS
light up consecutively from left to right, after which communication
with the recorder starts.
The remote panel can not be used as a stand alone Sony 9 pin
controller to control other manufacturers' equipment.
