SnakeSys User Manual 7 / 44

Note

If the unit product version is B4 MK2 or later the unit will remember the settings that you make in MagicQ Net Manager. Please

allow at least 40 seconds for the unit to store the information into ﬂash memory before removing the power. If the unit is left in

MagicQ ChamNet mode it will boot up with the settings that you made previously in Net Manager (MagicQ will not be required

to be connected to keep the port settings). This is a useful work around if you need to pre-conﬁgure port settings outside

the options that are available through the normal DIP switch settings for use without MagicQ. This save to ﬂash feature is not

available on B4 MK1.

2.8 DMX Buffer Mode

The SnakeSys B4 can also be used as a simple DMX buffer, giving 4 DMX outputs from a single DMX input.

For DMX buffer Mode DIP switch 1 should be in the up position with all other DIP switches down.

2.8.1 Rotary Encoder Function, DMX Buffer Mode

The rotary encoders when the unit is operating in DMX buffer mode allow some adjustments to the DMX output protocol,

including DMX packet rate, DMX packet length, DMX break length and overall DMX frame timing.

Note

These are advanced options, if you do not fully understand what the DMX packet timings actually adjust with regards to the

DMX output, or you would just like the default setting you should set both encoders to 0 when using DMX buffer mode.

Note

A version of the tables below is also written on the base of the B4 unit for quick reference in the ﬁeld.
