Bandwith usage of Control Links
Note
Function and configuration of Control Links is not part of this article and is described in the following sections:
Toolbox 8 - Control Link
Toolbox 9 - Control Link
Bandwidth usage of a single Control Link depends on the configuration and the current content of the replicated module. In order to define a understandable terminology, this article uses the labels from the following Control Link schematic.
The following table lists the average results of a set of bandwidth measurements that were made on several setups/ Control Links under firmware version 9.1:
| Module(s) in Control Link | Configuration | Bandwidth Main Studio Console → Remote Console | Bandwidth Remote Console → Main Studio Console |
| 1 x 52-5614 SX2 | standard, noise on all PPMs, 4 x FaderPPM + 1 PPM | 161 kBit/s | 5,5 kBit/s |
| 1 x 52-5620 SX2 | standard, noise on all PPMs, 6 x FaderPPM + 1 PPM | 192 kBit/s | 8,0 kBit/s |
| 1 x 52-5614 SX2 + 1 x 52-5620 SX2 | standard, noise on all PPMs, 10 x FaderPPM + 2 x PPM | 360 kBit/s | 17 kBits/s |
| 1 x 52-4012 | 64 x PPM with noise | 1600 kBit/s | 1,5 kBit/s |
| 1 x 52-4060 | 8 x Fader 52-4231 with noise | 37 kBit/s | 8,0 kBits/s |
The table shows that most of the traffic appears in the direction Main Studio Console → Remote Console. In the opposite direction the traffic is way below and normally is set between 2 kBit/s and 20 kBit/s. That highly depends on the amount of faders / encoders / buttons and the number of changes (e.g. moving 8 faders at the same time) at the module and at the same time.
While connecting (enabling a Control Link) or updating (e.g. changing a view) bursts are also possible.
