I've just been converting the code for the Houstons display.
It is sent as sysex in hex ASCII as two strings, the first for the upper line of the display, the second for the lower:
F0 39 48 01 01 28 20 20 20 20 20 20 20 20 43 6f 6e 6e 65 63 74 69 6f 6e 20 74 65 72 6d 69 6e 61 74 65 64 2e 2e 2e 20 20 20 20 20 20 20 20 12 f7
produces this:
*9H ( Connection terminated... ¸
on the top line,
F0 39 48 01 2d 21 53 74 65 69 6e 62 65 72 67 20 4d 65 64 69 61 20 54 65 63 68 6e 6f 6c 6f 67 69 65 73 20 32 30 30 34 5d f7
Produces This:
*9H -!Steinberg Media Technologies 2004]¸
on the bottom line.
I think that's just about everything on the device covered!!
