2. Connection:
Keyboard interfaces are on the back of the keyboard. The keyboard is equipped with
multiple interfaces, which includes RS485, VGA output, video input and USB, Easy to
connect and control a variety of external devices.（Figure: 2.1）

7
2.1 Interface instruction
RS485 interface is on the two green terminal seats of the keyboard connection lines.
In the keyboard directly controlling mode，RS485（A+，B-）Collects Dome Cameras；In
the matrix controlling mode, RS485 can collect other Keyboards.
Transfer RS485 interface to RS485-USB converters（picture 2-1.1）, then insert it into the
USB interface of the Keyboard. So when using NKB built-in computer’s related monitoring
software, it will be more convenient to use the keyboard rocker to control monitoring
equipment.
VGAinput interface is used for taking the keyboard as a display device. The keyboard can
insert equipments with VGA output like PC host and DVR. The maximum input resolution
it supports are 1024X768,800X600。
USB interface, used for PC host communication, it is connected to PC host via USB. At
this time the keyboard can be used as Mouse equipment. And the Video Input Interface on
the keyboard is used for receiving camera’s video signal externally.
2.2 Connect to matrix
The keyboard can control PELCO CM6700, CM6800 matrix. Here below taking keyboard

connecting PELCO CM6700 matrix as an example, explain the connection between
keyboard and matrix.
2. 3 Connect to PTZ speed Domes
The keyboard connects Dome cameras via RS485 interfaces. And the RS485 interface of
Dome camera is on the connecting plate of Suspension hanger within the upper cover.
Pull the Metal button in the hanger, and open the connecting plate, upon which there is a
four-control/power plug seat. According to the logo above, can find the corresponding
RS485 (A +, B-) interface.
Dome cameras made by different manufacturers may have different ways of connection.
Please refer to the Installation manual of the Dome cameras when connecting the
Keyboard.

A+B-
2.4 Connection in security system
Controller can directly connect to the PTZ speed dome or indirectly connect to the Matrix,
through the matrix to control the PTZ speed dome as (Picture 2-4.1). Controller and PTZ
Speed dome will connect to the RS485 in Parallel. Each controller can control the PTZ
speed dome independent. And in this situation, it must have one mother controller (Mark
controller ID as 1, Baud Rate 9600bps) as（Figure 2-4.2）
Figure 2-3.1

Attention
1、One RS485 bus line can connect the 32pcs controller and PTZ speed Dome directly or
indirectly, So one controller can control the 31pcs PTZ speed dome directly most.
2、In the system, it can connect the 4pcs controller most, each controller ID will different.
