3.3.6 Keyboard Controlling
If you want to unify control more than one DVR, you have to use the series keyboard (we suggest user using one series keyboard to control more than one DVR in the same model).
The function of the keyboard is the same with the front panel of DVR. (Note: the keyboard must be added with the protocol from our company and go through the test of our company).
Take the RS485 interface series keyboard for example:
3.3.7 Intercommunication Port
1. “Main Menu” -> “System Setup” -> “COM”, to setup the COM number and COM device (series keyboard).
2. Connect between RS485+ of the keyboard and RX+ of the DVR, also RS485- of the keyboard and RX- of the DVR.
3. Connect with the power supplier.
4. Choose the “Switch” key to change mode to DVR mode, the default is “DVR-01”, “01” is address code of keyboard.
5. Address code of keyboard: choose the “shift” key to enable the up key of the keyboard, then click “address/enter” to
input the host address code, then you can control the DVRs.
Intercom interface multiplexes with 1st audio input interface, support active or passive microphone.
Note: The detail set of keyboard can refer to the user manual of keyboard.
