 High current fused outputs
 Fully selectable DMX base address
 On-board terminate setting (120 Ohm)
 Full isolation from DMX connection for maximum reliability
 Power and Data indicator LEDs
 Built in stand-alone programs
 Protection against reverse power input
 Custom builds available  
Specifications:

Size:
43 x 82 mm (PCB), 14mm max. above PCB and 3mm below.

Fixings: 4x 3.25mm holes on 74.61 x 35.56mm centres.

Weight: 30g approx. Power connection: 2x Screw terminals, 5mm pitch. Input voltage: 12 or 24Vdc, specified when ordering.

Quiescent current: 30mA at 12Vdc (no DMX signal).

DMX connection: 3x Screw terminals, 3.81mm pitch.

DMX input: RS-485 compliant.

Output connection: 6x Screw terminals, 5mm pitch.

Output current: 5.0A maximum (fused) per channel.

Output voltage: Same as input voltage.

PWM Frequency: 100Hz approx.

Fuses: Fuses F1, F2 and F3 protect outputs 1(Red), 2(Green) and 3(Blue) respectively and should be F5A type unless custom build, in which case see custom build sheet supplied.

F4 protects the control circuit and is F500mA for 12V, or F2A for 24V, 1206 type.
DIP Switch Settings:
1= DMX base address (1)   6= DMX base address (32)
2= DMX base address (2)   7= DMX base address (64)
3= DMX base address (4)   8= DMX base address (128)
4= DMX base address (8)   9= DMX base address (256)
5= DMX base address (16) 10= Terminate (on/off)

DMX Addressing (Firmware version 1.1):

Address 0 - Sleep mode (device can safely remain on DMX bus) Address 1 to 508 - Normal DMX function
Address 509 - Steps through each output channel sequentially Address 510 - Cross fade pattern, R-G-B-R-G-B-R….
Address 511 - All channels on full (lamp test)
