I have a Samsung SCC-421P integrated camera, and P-991MJ is printed on the circuit board of the Yuntai decoder, which was produced in November 28. How to set this up?

you should have taken the previous picture. Generally, it is like this:

1. Connecting signal lines: Connect the signal lines from the host computer to the terminals marked "RS485+ and RS485-" in the decoder, and the middle pin of the three-core interface is a shielded ground input terminal, so it is unnecessary to connect them.

2: Connect the control lines of the pan/tilt, and connect all the control lines of the pan/tilt to the terminals marked "up, down, left, right and auto" on the decoder one by one. The male * * * line of Yuntai can only be connected to the male ***(com) terminal next to "Shang", but not to the male * * * terminal next to "IRIS".

3. Connect the pan/tilt, camera and lens power supply: a. Pan/tilt power supply: the decoder can drive AC 24V pan/tilt or 22V pan/tilt. If you connect 24V AC Yuntai, you don't need to make any changes. If 22V AC Yuntai is connected, pull out the jumper of "Yuntai Working Voltage Selection" and switch it to a 22V jumper. The 24V terminal is vacant, so be sure to pay attention to safety during installation. Before powering on, please check the wiring of decoder and pan/tilt again, especially the driving voltage of pan/tilt to prevent burning out. B. Camera power supply: The decoder can drive 12V DC camera and 24V AC camera. If you are connecting a 12V DC camera, please connect the power supply of the camera to the "12V DC output" interface on the decoder, and pay attention to the positive and negative polarity when connecting. The 24V AC camera can be connected in parallel to the "24V Yuntai Power Input" interface on the decoder. C. Lens power supply: the voltage output of the lens control terminal of the decoder is 9 ~ 12V. When wiring, please note that the male * * * terminal (ground terminal) of lens signal and the male * * * terminal (ground terminal) of Yuntai signal are impassable and cannot be used together.

4: Connect auxiliary switch: The decoder can output three independent switch signals, and can connect wiper and spotlight. The electric shock load of relay is 22V, 7A.

5: setting the address code: please set the address code of the decoder according to the actual situation of the project, and the address of the decoder is determined by the toggle switch. The 4-digit dip switch is used to select the communication protocol, and the switch to "on" means 1. When it is "", choose the 8-bit dip switch of PELCO-D protocol, mainly choose baud rate and address, and dial "on" to indicate 1. When 1 and 2 are dialed to , it means that the baud rate is 24bps, and when 1 and 2 are dialed to 1, 96bps is selected. 3-8 digits select the communication address.

the control of pan/tilt can't use the acquisition card, but use the monitoring software, which has this function.
