Boulder Link
Boulder Link is a means of interconnecting most Boulder products so
that their microprocessors can communicate and pass important
information. Among the key features, Boulder Link allows sequential
turn-on of power ampliers and other products when the 1021 is
brought out of Standby mode. When the 1021 is set as the Master,
power ampliers can also send messages to the player, which are
then shown on the display. When the 1021 is installed in a Boulder
Link enabled system with a Boulder preamplier, the volume control
of the preamplier will respond to commands from a remote control,
however the 1021 volume setting will not change.
The following is a description of how volume control works with the
1021 CD Player and preampliers using Boulder Link.
The general rules for Boulder Link and remote control transmissions
are as follows:
Only the component that is set to the 1. MASTER position looks for
IR remote control commands.
If the Master can decipher an IR remote transmission, the 2.
Master will perform the action requested and also send out
any Boulder Link or IR commands accordingly.
If the Master cannot decipher the IR remote transmission, or 3.
the remote address is wrong, then the Master packages the
code and sends it out through the Boulder Link connection to
be used by any Slave that can utilize it.
If a Slave receives an IR remote package via Boulder Link, 4.
it will try to decipher it, and if the address is correct (for the
Slave), it will perform the action requested but will not send
out any results to the Boulder Link buss. This prevents an
“echo” from being generated on Boulder Link.
The 1021 breaks rule #2 in that even though it is able to decipher
remote Volume Up/Down actions, it also sends remote Volume
Up/Down transmissions out via Boulder Link to be utilized by any
preamplier that is connected to the system.
