Setting DMX Address by Jumper Wires
A new Hydra has DMX address 32 set as default.
There are presently 2 different ways to program the DMX Address:
1) Use wire jumpers connected from ground to specified inputs.
2) Use 1 jumper wire and the Set push button switch on the front panel.
This section explains method 1, using wire jumpers.
Connect input 0 to terminal “G” on the DMX port.
If any input 1 – 9 is grounded, the Hydra will add the values of the inputs for the DMX address.
If no inputs are grounded, the Hydra allows you to enter the address by the Set push button.
Each input 1 through 9 has a value as follows:
1 = 1
2 = 2
3 = 4
4 = 8
Select all inputs needed to add up to the DMX address you desire.
5 = 16
Ground these inputs to the DMX terminal G.
6 = 32
7 = 64
8 = 128
9 = 256
For any method of setting the DMX Address, you must hold the Set push button pressed, apply
power, and then release the button.
As an example, if inputs 1, 6 and 8 are grounded:
The values add up as 1 + 32 + 128 = 161.
The Hydra will pass serial commands received on DMX address 161 out to the Sprite.
See wiring and an example on the next page.
The DMX address will be saved in memory. The Hydra will start in DMX Mode at this address
every time power is applied, until you set a new Mode or DMX address.
The Hydra will flash the Yellow LED to indicate the address. Digit 1, pause, Digit 2, pause, Digit 3
