1) When the first digit nixie tube displays a, it is in DMX512 state, indicating that the decoder enters DMX512 signal control state. At this time, its output can be controlled by connecting the main control console through the network cable. For example, the nixie tube displays A001, indicating that the starting address code of the decoder is 001, and the following two channels correspond to 002 and 003 respectively. If its string is connected to another decoder, the starting address of the lower decoder is 004, and the other two channels are 005 and 006 respectively. By analogy, multiple decoders can be continuously connected for multi-point independent control. If the start codes of the connected decoders are the same, the function of synchronization control can be realized

2) When the first digit nixie tube displays h, it is the built-in mode state, indicating that the decoder enters the built-in program mode operation state. The built-in mode table is as follows:

3) When the first digit nixie tube displays s, set the state for the built-in speed. This state is only used for h-08 and H-09 modes. Press the set key to enter the speed adjustment, and a total of 11 levels of speed selection are realized through the - and + keys. Other modes are invalid 2, Key function description:

The three keys are named set, - and +. Their functions are as follows: Set: function switching key. Long press (about 2 seconds) this key to switch between a and H States, and light press to switch between H and s states. +: press the add key once to add 1 to the last three digits of the data tube code. When setting the address code, press it to realize rapid increase. Note: the maximum value of the address code is 512, and then add 1 to return to the value 001;

－: back down key. Each time you press it, the last three digits of the data tube code will be reduced by 1. When setting the address code, press it to realize rapid decrement. Note: after 5S without any operation of the key, the decoder enters the self-locking working state. At this time, the brightness of the nixie tube becomes dark, and the light pressing of the three keys is invalid. If you need to wake up the key function, long press any key (about 2S) to unlock.
