12.Calculation method of lamp start address code:
The starting address code of the current fixture is equal to (the starting address code
of the previous fixture) + (the number of channels of the fixture)
1: The starting address code value of the first lamp is A001.
2: The number of basic channels of the controller should be greater than or equal to
the total number of channels used by the lamp.
3: Note: When using any controller, each lamp must have its own start address code.
The start address code of one lamp is set to A001, and the number of channels of the
lamp is 17CH; then the start address code of the second lamp is
Set to A018; the start address code of the third lamp is set to A035; and so on, (this setting
method also needs to(Different consoles are available)
13.Maintenance and maintenance:
Shutdown operation: before each shutdown, turn off the LED for 10 minutes in advance.
Let the heat dissipation fan quickly discharge the heat generated in the lamp during use,
which can extend the life of the accessories in the lamp, especially the LED! In order to
ensure that the lamp can operate stably, it should be kept clean. Before disassembling the
lamp for repair or starting maintenance work, confirm whether the power supply is
disconnected. It is very important to keep the lamp clean and clean. Please clean it
regularly, not only Maintain the maximum brightness output, and can also extend the
service life of the lamp. It is recommended to use high-quality glass cleaner and a clean
soft cloth to clean it. The dust inside the lamp is cleaned at least once every six months.
14.Precautions for the use of RDM RMD
RDM is an extended version of the DMX512-A protocol. It is a remote device management
(Remote Device Management) protocol. The traditional DMX512 protocol communication is one-way
communication. The protocol is based on the RS-485 bus. RS-485 is a time-sharing multipoint,
half-duplex protocol. , Only one port is allowed to output from the host at the same time, so, pay attention
to the following points when using RDM:
To use a console or host device that supports RDM protocol host;
To use a two-way signal amplifier, the traditional one-way signal amplifier is not suitable for the RDM
protocol, because the RMD protocol requires feedback data, and the use of a one-way amplifier will block
the returned data, resulting in the failure to search for the lamps;
The lamp must be set to DMX mode to ensure that there is only one host on the signal line;
A 120ohm impedance matching resistor must be inserted between the terminals 2 and 3 of the terminal
plug. When the signal line is relatively long, the use of differential signals is more stable and beneficial,
which is beneficial to the quality of communication;
When it appears that the lamp accepts DMX control, but cannot search for the lamp by RDM, first check
the signal amplifier, and then check whether there is a bad connection between the 2 and 3 lines of the
signal line.
