Switchpack DMX Operation
DMX Address setup
The DMX start address for each Switchpack is set by the 3 digit thumbwheel.
For example if the thumbwheel is set 001, then DMX channels 1-12 will control
SwitchPack outputs 1-12 etc. A second SwitchPack should have its DMX start
address set to 013, so its outputs follow DMX channels 13-24 etc.
Valid thumbwheel settings are 1-501 for the 12 channel version, and 1- 507 for the 6
channel version.
On/Off/DMX Mode set per channel:
Press any Key- the Channel cycles through 3 states:
1/ Channel always Off - Key LED blinks on briefly
2/ Channel always On - Key LED blinks off briefly
3/ Channel on DMX control- Key LED is either on or off (not blinking) depending the
DMX control level for that channel
The DMX levels have hysteresis levels fixed at On at 60%, and Off at 40%. The
behaviour is:
If Off, the channel is only set On if the DMX level exceeds 60%
If On, the channel is only set Off if the DMX level drops below 40%
The On time and Off response time depends on the security time settings described
below.
DMX Security Modes
(6 and 12 chn):
Enhanced security delays may be chosen so that received DMX levels are averaged
over time. The longer time settings provide greater security to accidental changes in
the SwitchPack outputs:
Hold two middle centre Keys for 2 secs, then release Keys on a short flash- the fast
flashing LED shows the current DMX security setting:
LEDs

0-Full times (secs) Instant 0.15s 0.3s 0.75s 1.5s 3s
Press a new Key 1-6 to change to a new DMX security setting.
