which include metal, glass and water (if the barriers include some of these things,
the system may still work well but may require a higher power setting).
3.
Connect and power up the Transmitter and Receiver.
Connect an active
DMX source (such as a console) to the Transmitter and confirm it is receiving
DMX (on the Start Up menu, the display should read
DMX: OK
).
4.
Configure the Transmitter.
Using the 5 button Control Button Pad, navigate to
the RF Settings menu and set the Hopping Pattern and Broadcast Mode desired
(see Advanced Wireless Features for more on these selections). Based on your
settings, the Transmitter will calculate a unique SHoW ID which will be displayed
under
SHoW ID
in the RF Settings menu, and will also be displayed in the Start
Up menu.
5.
Configure the Receiver.
Using the 5 button Control Button Pad, navigate to the
RF Settings menu and set the SHoW ID to match the Transmitter. When
correctly configured with the right SHoW ID, the receiver should display
IN
RANGE
in the Start Up menu, and that message will alternate with the received
RF Signal Strength.
6.
Check the RF Signal Strength on the Receiver.
RF Signal Strength is
displayed in the Start Up Menu, and is also displayed (continuously) in the Misc.
Settings menu. The RF Signal strength ranges from -120dBi (weakest) to -40dBi
(strongest). You may notice that the signal strength level varies over a range,
that Is normal.
7.
Adjust Transmitter Broadcast Power.
Using the RF Settings menu in the
Transmitter, adjust the power setting while monitoring the RF Signal Strength in
the Receiver. Select the lowest power setting that produces between -70 and -
50dBi signal strength.
8.
Adjust Receiver Broadcast Power.
This is to insure that during RDM
operations the receiver can properly communicate with the Transmitter. Note
that adjusting the Receiver Broadcast power has no effect during plain DMX
transmission. If RDM is not being used, you can leave the Receiver at the default
setting of 10mW.
Configuring Multiple Receivers
Optimizing a system with multiple Receives is much the same as working with a single
receiver, except that you must consider the weakest wireless connection.
9.
Configure your Transmitter and Receivers
. Configure your Transmitter and
Receivers as above in steps 1 – 5. All receivers must be set to the same SHoW
ID.
10.
Check the RF Signal Strength on the Receivers.
Check all of your Receivers
and determine if any of them have weaker received signal strength than the
others. Look for units that are concealed in props or set pieces, located behind
barriers, or are significantly further away from the Transmitter than the other
Receivers in the system.
11.
Adjust Transmitter Broadcast Power.
Using the RF Settings menu in the
Transmitter, adjust the power setting while monitoring the RF Signal Strength in
the Receiver that you have identified as having the weakest reception (highest –
dBi reading). Select the lowest power setting that produces between -70 and -
50dBi signal strength.
12.
Adjust Receiver Broadcast Power.
Again, this is to insure that during RDM
operations the receivers can properly communicate with the Transmitter. Note
