Table 12 - DMX512 Recommended Wire
Analog Input, 0-10 VDC (Optional)
A third type of control input signal, 0-10 Volt DC, can be used if equipped with the
optional Analog DC Control Card. This signal varies between 0-+10 VDC and can
be used to control the dimmer outputs or for photo cell/daylight harvesting
application.
This section relates only to use of the analog input for direct 0-+10V
control. For Protocol/Daylight harvesting applications see page 71.
Table 13 - Analog Control Input Signal
Varying this signal from 0 VDC to +10 VDC varies the AC output voltage from zero
to virtually full line voltage.
Analog connections can be hooked up in two ways:
1 Analog devices powered by external source
2 Analog devices powered by a-2000 cabinets
If +12 VDC is supplied from the analog card to power analog controls, the
common MUST BE
connected to the TB9 terminal on the main control
module board - See Figures 22.
Photocell Input
See page 71 for details on photocell operation. This section relates to the
connection of the photocell device to the a-2000 dimmer cabinet.
