*1. Input pin: TTL level, w/ internal pull-up (47kΩ)
Output pin: Open drain output (Vmax=12V, maximum sink current/pin=75mA)
Power supply pin: Output voltage Vp=5V, Max. output current Imax=300mA
*2. 4 pin=+12V, 3 pin=GND, Lamp nominal power: 5W, Brightness (voltage) can be
adjusted from the software.
Electrical characteristics
All faders are nominal when measured. Output impedance of signal generator: 150 ohms
 Frequency Response. Fs= 48 kHz @20 Hz–20 kHz, referenced to the nominal
output level @1 kHz
