DMX signal cable is shielded wring-wires such as microphone cable. DMX signal has positive polarity and negative polarity. It must be adverted especially when making a cable with connectors.

In using, connect DMX output socket of a console and DMX input socket of DA48 Decoder with a DMX signal cable.

If need, connect DMX output socket of this set and DMX input socket of the next set with a DMX signal cable once more. Such-and-such connecting. Up to the last set.

0~10V Analog Signal Output Connectors

Two D25 type connectors output 48 channels 0~10V analog signals aggregately.

One outputs CH1 ~ CH24, the other outputs CH25 ~ CH48.

The relation between the pins of the connectors and output channels is as follows:

Setup DMX-512 Address Code and output Control memory Mode

The DIP encoder on the rear panel of DA48 Decoder takes on double-duty functions: a.

Confirming the local inception address number by binary encoding;

b. Confirming output state memory mode.

2.3.1

Confirming DMX-512 Local Inception Address Number

“Local Inception Address Number” is confirmed by 1~9bit switches of DIP encoder. No.1bit is LSB, No.9 bit is MSB. In all the address number is 512. The “Inception Address Number” is the channel number code of DMX signal that is accepted by the first channel of this set, the second channel accepts DMX signal code of “Inception Address Number” + 1, the third channel accepts DMX signal code of “Inception Address number” + 2, etc. (If Local Inception Address Number is “0”, then the first channel of this set accepts No.1 channel code of DMX signal.)

The relation between bit value of DIP encoder and DMX channel code may be educed by two methods:

2.3.1.1

By Calculating

“DMX Local Inception Address Number” keeps to the formula below:

[ The sum value of 1~9bit switches of DIP encoder ] + 1 = DMX inception address number Moving-down No. “n” digit switch of DIP encoder, (set “1”), obtains its bit value; Otherwise, its bit value is “0”.

Example 1: DMX inception address number is “38” Set No.1bit, No.3 bit and No.6 bit to “1”, the others to “0”.

The sum value of 1~9bit of DIP encoder is 1+4+32=37.

The result plus 1, then, DMX inception address number is 38.

Namely: [ 1 + 4 + 32 ] + 1 = 38

Example 2: DMX inception address number is “226” Set No.1bit, No.6 bit No.7 bit and No.8 bit to “1”, the others to “0”.

The sum value of 1~9bit of DIP encoder is 1+32+64+128=225.

The result plus 1, then, DMX inception address number is 226.

Namely: [ 1 + 32 + 64 + 128 ] + 1 = 226

2.3.1.2

By Tabulating

The relation between switch position of DIP encoder and DMX inception address number is as the details in《DMX Address Encoding Table》.

2.3.2

Confirming Output State Memory Mode

Confirming the output state memory mode of DA48 by No.10bit switch of DIP encoder. While the position of No.10bit switch is “N”(moved at downside), this set is in data memory state. It means of DMX-512 control signal broken off abruptly, the current output state of every channel is not changed. Whereas, the position of No.10bit

001 002 004 008 016 032 064 128 256 N/S

switch is “S”(moved at upside), The data memory function is closured.
