Advanced Setup
You may want to take advantage of additional features, such as assigning a group of
SNAP DMX adapters to different Universes, or enabling security by assigning a unique
security key. The following section provides information for all aspects of configuring
your SNAP DMX adapters.
How to Reset to Factory Defaults
It is easy to reset a SNAP DMX adapter back to the factory default configuration and
parameters (Universe = 1; all four Security Keys = 0; Mesh Hop = 0). This procedure will
clear any settings you may have applied and re-assign the factory assigned settings. To
reset to factory defaults, perform the following steps:
1.
Unplug the USB connection from the SNAP DMX adapter so it loses power.
2.
Hold down the Mode button.
3.
While continuing to hold down the Mode button, apply power to the SNAP
DMX adapter by plugging in the cord again. Continue holding down the Mode
button for approximately 3 seconds. You should see all three LEDs rapidly cycle
through red/amber/green colors. Continue holding the button until this pattern
stops (LED C will turn green). This indicates that the unit has rebooted with
factory default settings.
Configuration Modes
The Mode button is used to configure SNAP DMX adapters. Long presses of the button
will cycle through a set of configuration modes, defined below. While in each
configuration mode, short presses of the button will cycle through setting the values for
the mode.
Universe Configuration Mode
The Universe Mode allows you to have up to 16 independent universes of DMX devices,
with each universe controlling up to 512 DMX channels independently. In order for two
DMX devices to communicate with each other, they must be assigned to the same
Universe. By default, SNAP DMX adapters are assigned to Universe 1, but this is easy to
change.
Security Key Configuration Modes
There are four key modes, which are used to set the four values that form the security key
when security is enabled. Each of the four key modes can be set to one of 16 values, for
more than 65 thousand security key combinations. In order for two DMX devices to
communicate with each other, the SNAP DMX adapters must have the same four values
set for their security codes. If all four key values are set to zero, no security encryption is
used.
