Jog a Channel

Individual DMX channels may be jogged up and down. In this mode, it is not required to know the channel’s exact value. Rather, it can be added to or subtracted from in arbitrary amounts, up to the limits of 0 or 255. This command may be useful when implementing bump buttons on a human interface control panel.

If a channel is jogged past the maximum or minimum values allowed in DMX, the command is ignored.
