DMX512
Base
Address
The BCD inputs are used to set the DMX base address. The inputs
are set up for connection of three standard Binary Coded Decimal
Thumbwheel switches. The BCD inputs are active low, i.e. to select a
base address of 001, connect UNIT1 to ground and pull up all other
BCD inputs. Valid addresses range from 001 to 512.
The relationship between DMX512 channels and outputs is shown
below:
DMX512 Channel Relay controlled Analogue Output controlled
DMX Base + 0 SW 1 Analogue 1
DMX Base + 1 SW 2 Analogue 2
DMX Base + 2 SW 3 N/A
DMX Base + 3 SW 4 N/A
DMX Base + 4 SW 5 N/A
DMX Base + 5 SW 6 N/A
DMX Base + 6 SW 7 N/A
DMX Base + 7 SW 8 N/A
DMX Base + 8 SW 9 N/A
DMX Base + 9 SW 10 N/A
DMX Base + 10 SW 11 N/A
DMX Base + 11 SW 12 N/A
DMX Base + 12 SW 13 N/A
DMX Base + 13 SW 14 N/A
DMX Base + 14 SW 15 N/A
DMX Base + 15 SW 16 N/A
Test Mode
The BCD inputs are also used to enter test mode.
When Test mode is active, the DMX512 input is disabled.
When the Hundred inputs are set to either ‘6’ or ‘7’ Test mode is
active. The Hundred input sets the intensity, while the Ten and Units
inputs select the channel.
The following examples show the operation:
