RS232 Connection (Single Unit)
A typical interface set-up might involve running an RS232 link from laptop or a
desktop computer to a
DP6i set up as a master unit. The diagram below shows this
method of connection, the required menu options are also given. Note that the
RS232 cable must be a 1-1 connection type, NOT a null modem cable (which has
connections crossed internally).
Shadow ID Numbers
Shadow ID numbers allow extra units to share the same ID and follow the settings of
the ‘main’ ID. This is useful for larger systems (for example anything above a 3-way
stereo system) where it is only necessary to set up one side of the system, and allow
the other unit to track it identically.
Using the shadow IDs in this way also reduces the apparent system complexity within
Audiocore. This is due to the fact that shadow ID’s NEVER send back any
settings to Audiocore and because of this will NOT appear in the list of
connected units.
They can be thought of as listening to and acting upon all information addressed to
them, but not replying. Up to 31 shadow units may be connected and assigned the
same ID as the ‘main’ unit, but remember that the maximum total units on any one
RS485 network is 32.
Shadow ID numbers are accessible when the unit’s interface is configured as a slave
(interface types 06 – 08), and will appear after ID number 32, starting from 01 again,
but with the ‘SHADOW’ LED illuminated.
