I. Summary
The keyboard controller is used for terminal receivers such as the intelligent speed dome and the decoder etc.
Taking the EIA/RS-485 electrical interface between the keyboard and the receiver, one keyboard can control
as much as 32 speed dome and decoders without driving the bus and the maximum communication distance
between the keyboard and the receiver is up to 1.2 km. It is very easy for operating and setting the speed
dome camera. The controller is also to control the terminal receiver to achieve the function of controlling
