When the decoder controls the pan/tilt head of the 24VAC pan/tilt whose power is greater than 45W or controls other types of voltage, only the jumper marked “JP3†and “JP4†on the decoder should be disconnected, and the AC24V power will be high. The power supply or other voltage corresponding to the type of load voltage can be input from the terminal block labeled "PTL" and "PTN" on the decoder board.
PTZ control connection: “PANRIGHT†is the pan tilt horizontally, “PANLEFT†is the pan tilt horizontally, “TILTUP†is the pan tilt vertically, “TILTDOWN†is the pan tilt vertically, and “AUTO†is the pan/tilt Automatic control end, "PTN" is PTZ control public end.
Water spray / wiper / camera / infrared light control voltage: 24VAC or 220VAC optional.
1. When using 24VAC control, the power supply is provided by the decoder. The maximum output power of the decoder power supply is 45W. At this time, the JP1 and JP2 jumpers on the decoder board must be shorted respectively. Special note: When using 24VAC control, the terminals marked “L†and “N†on the decoder board must not be connected to any input power, otherwise the decoder may be damaged.
2. When 220VAC control is used, the control power supply is provided externally. At this time, the JP1 and JP2 jumpers on the decoder board must be disconnected. Otherwise, the decoder will be damaged. The external power supply is marked with “L†on the decoder board. Input terminal with "N", terminal marked with "E" is ground Note: Terminals marked with "E" must not be connected with "L" or "N".
3. Decoder factory default value: 24V/AC voltage is provided externally (JP1, JP2 are shorted)
4. When the water spray/wiper/camera/infrared light and the PTZ control power are all provided by the decoder, the total power of the water spray must not exceed 45 W. Otherwise, the decoder may be damaged due to overheating after long-term use.
5. When the power of the 24VAC type load is greater than 45W or the load of other types of voltage is controlled, only the jumper marked “JP1†and “JP2†on the decoder should be disconnected, and the AC24V high-power power supply or other corresponding to The voltage of the load voltage type can be input from the terminal block labeled "L" and "N" on the decoder board.
Aperture/focal length/zoom control: The 12VDC aperture, focal length, and zoom three control lines must be respectively connected to the three control terminals marked “IRISâ€, “FOCUSâ€, and “ZOOM†on the decoder, and labeled “LENSCOM†as Camera control common.
The decoder also provides a set of camera control voltage: DC voltage of DC12V/850mA load capacity, after the jumper marked “JP-DC†on the decoder board is shorted (shorted at the factory), according to the keyboard operation Note that the power output can be turned on or turned off [Note: Because the pan/tilt lens control voltage (AC220V or other type of voltage) and the camera control voltage (DC12V) are controlled by the same operation method, when the decoder is marked with " When the JP-AC†and “JP-DC†jumpers are shorted, both the lens voltage and the camera voltage are controlled. If the lens voltage or camera voltage is not desired to be controlled, the decoder is simply marked “JP- Jumper of AC" or "JP-DC" can be disconnected. Factory setting: "JP-AC" and "JP-DC" jumpers are shorted.
The electrical interface protocol with the decoder: RS-485 decoder marked "RS485+", "RS485-" means that the communication terminal.
The power indicator and communication indicator on the decoder indicate that the decoder has received power when the red indicator light is on. When the communication indicator flashes, the decoder has received valid data.
A dial switch marked “SW-10†on the decoder is used to select the address of the decoder. “10†is the highest address, “1†is the lowest address, and hexadecimal coding. Decoder address selection range: 0 to 1023 When the keyboard is controlled by the decoder, the address of the decoder must match the address of the camera selected by the keyboard.
The input power of the decoder is 220V, and the three-core terminals are marked as follows:
FireWire (red line) Ground line (flower line) Neutral line (Green line)
Special attention of the user: Do not connect the live or neutral wire to the input of the ground wire, otherwise the decoder may be damaged. If the user only has the input of the live wire and neutral wire, the input of the ground wire can be left empty before the power is supplied to the decoder. , It is recommended that you do not connect the load, and turn off the power switch on the decoder. After ensuring that the connection is correct, you can power on.
Of course, dust removal and anti-frost is also the use of less windshield wiper and heating in the south, so generally neglect to pay attention to explain the wiring method and the specific use method. In addition, there are very few explanations for the connection of infrared lamps. Infrared lamps, such as the connection with the decoder, are of little control. Only the effect of centralized power supply is achieved, and currently there are mostly 30W and 50W power decoders on the market. In the project, the power load of the decoder should be reduced as much as possible.
Although it is now possible to combine alarms for monitoring and anti-theft and to implement integrated control in the project, the control module of the actual alarm is an independent body. Taking a hard-compressed PC-type hard disk recorder as an example is basically an external alarm box. It is actually an alarm host that shares the common protocol with the hard disk recorder. The same way as the 485 signal. However, the function of arming and disarming can be basically operated on the hard disk recorder. This basically integrates the control and integration of front-end devices into one.
Of course, many matrices now have a loop-through function or a hard disk recorder has a loop-through function. Here we talk about the wiring method when the basic hard disk recorder and matrix are combined. The following figure shows the connection of the actual connection with the definition of the matrix output signal.
