Cue Light Outstations (Continued)
Anywhere from 1 to 40 Outstations can be connected to the
Master Station.
Rectangular 25mm/10mm Go and Standby lamps are
bright, wide angle and dimmable in 5 steps from 5 to 100%.
The Go and Standby lamps consist of four LEDs for each
colour. The LEDs are fed from 2 drive circuits with two LEDs
per circuit to provide redundancy should any of the LEDs or
drive circuits fail.
The Confirm button is back lit so you can find it in the dark.
The back light only comes on when error free
communication is established with the Master Station. The
backlight winks slowly if data is lost as can happen if the 2
data conductors are shorted together.
Any Outstation can Call the Master Station. An Outstation’s
Confirm button has 2 functions. If a Standby cue is waiting
to be acknowledged (Standby lamp flashing), pressing the
Confirm button will cause the Standby lamps to burn
steadily. Pressing the Confirm button at any other time will
light the Call lamp on the Master Station.
The address of any Outstation can be changed in a few
seconds without the use of any tools or fiddly DIP switches.
See Changing an Outstation’s address (page 22).
Outstations may be connected using either daisy chain, star
and/or loop wiring topologies. Outstations can be wired up
in any order. Outstation #2 does not have to follow #1 in a
daisy chain.
Multiple Outstations can be used on the same channel by
setting additional Outstations to Eavesdrop Mode.
See Multiple Outstations per channel (page 18).
Outstations can be added or removed while the power is on.
Flush mounted Confirm button, Go and Standby lamps are
virtually impossible to break or shear off.
The 2mm steel outer case has a total of 6 mounting holes
including a 10mm hole for attaching a hook clamp. A 3/8"
microphone stand mount is at the centre of the rear cover.
When mounted to a microphone stand with the front of the
Outstation facing the ceiling, the Outstation can be viewed
from 360 degrees.
The Outstation data is balanced and uses transformer
isolated RS485. (RS485 is what DMX uses.)
The data uses a Group Encoding scheme with digital
FM modulation for excellent noise immunity and error
detection.
Data is slew rate limited to reduce radiated electrical
noise to a minimum.
Outstations are powered by the Phantom Power
principle where power is sent down the data pair with a
ground return.
