Every RM220-020D Fader Module of the RM2200D has a "4-character ASCII display" for each channel.
Modules with a larger number of ASCII characters for each fader channel are neither available, nor planned or feasible for the RM2200D.
Nevertheless, it is possible to define channel names with up to 16 characters in the PC software. The PC software shows up to 16 characters, depending on the number of faders and the resolution of your computer monitor. However, only the first 4 characters of these channel names will be used for the RM220-020D hardware panels.
Please use an additional PC monitor as extension if longer channel names are necessary.
