"test" or Raw DMX mode

Hi folks -- we were given 2 lights (optima mojo scan 1x) that i dont have a manual for -- they are 3 channel scanners --- is there a way that i can send "raw" dmx to a given channel (i know what dmx channel they are on from the dips) so that i can start to determine the functions based on that. feed it value x get result y etc?

thanks
