The operation manual is mainly focused on all functions of PELCO-D, PELCO-P and COP-2
Protocols. For other different protocols, operations could be something different and those different
parts will be listed on “Supplementary Description of the Keyboard Controller” in details.
The keyboard takes DC12V power supply. Please confirm the voltage and polarity before the power
supply is switched on.
Do not place the keyboard under the rain or on wet place so as to avoid short circuit or electrical shock.
As the keyboard is a sophisticated electronic device, you should never open the case so as to avoid the
occurrence
of
trouble.
The keyboard has integrated multiple protocols, and you are pleased to select correct protocol and the
baud rate. When switching on power supply, take care of the selected protocol and the baud rate on the
first
