Booster Pro
Product code: 50789
Access via the Main Menu
You can configure the 8 output ports from the main menu. The configuration options are the same as via
the quick access. Refer to 6.9.4. Outputs on page 25 for more information.
Merge Function
The Booster Pro supports merging. Each output port can be configured to merge the DMX packets
received at Input A and Input B. See 6.9.3. Merge on pages 24–25 for the configuration settings.
The device supports the following merging modes:
HTP (Highest Takes Precedence)
When the HTP (Highest Takes Precedence) mode is selected, the DMX packets received at Input A and
Input B are compared and the DMX packet with the highest value is sent to the respective output port.
For example, if a lighting controller, connected to Input A, sends a dimmer value at 50 % and a lighting
controller, connected to Input B, sends a dimmer value at 80 %, at the output port there will be send
80 %. If you change the dimmer value at Input B to 0 %, the output value will be 50 %, sent by Input A, as
50 % is a higher value than 0 %.
HTP mode is recommended for controlling light intensity.
LTP (Latest Takes Precedence)
If you need to control parameters as color, pan and tilt, HTP mode will be a problem, as non-intensity
channels do not have ‘higher’ or ‘lower’ values. The color red is not higher or lower than green, and
gobo 1 is not higher or lower than gobo 2. Therefore, when working with effect lights or moving lights, it is
recommended to use LTP (Latest Takes Precedence) mode.
The LTP (Latest Takes Precedence) mode means that the most recently received DMX packet from Input
A and Input B will be sent to the respective output port.
For example, with two lighting controllers connected (Input A and B), the last lighting controller that
made any change will take precedence and will control the output.
A + B
With A + B mode the DMX channel is split into 2 parts. The first part is reserved for Input A and the second
part is reserved for Input B. The DMX packets received at the inputs are not combined. For example,
Input A sends DMX packets up to channel 256 and Input B starts at channel 257 on the same universe.
The starting address for Input B is user-programmable.
Backup
In backup mode Input A sends continuously DMX packets to the output. If Input A fails, Input B takes over
automatically. Input B serves as a backup in case of failure of Input A.
