Ÿ
By manually programming the packet size in 16 channel block increments
To setup the append packet size by *AUTO DETECT
1.
Select the APPEND SETUP by placing jumpers to the pins shown
2.
Connect a **DMX512 generating device into input A (e.g. lighting board) with a known DMX512 packet
size (output channel count) known or preset.
3.
Reset the power - The DMG enters the setup mode, indicated by LED A blinking
4.
If a valid DMX512 signal is connected to input A, the packet size is stored in
permanent memory. LED’s A and B will alternately blink indicating completion.
