5.! Wiring and Connections
The Pro Audio 4 control connections send data to control a device and receive data to display current status on the user interfaces or trigger a system
action. Each port type may support multiple protocols that are determined by the logical connection within Blueprint.
5.1.! RS-232 Wiring
TIPS:
–! Savant recommends planning control connections and protocols to be used prior to building any cables and connecting equipment. This will ensure
that devices will respond to commands and will not be damaged by an incorrect cable configuration.
–! When installing wire in screw down terminals, strip a 1/4 inch of insulation from each wire and twist the strands together. This will allow for the
exposed wire to be inserted into the terminal up to the insulation eliminating stray strands that may cause shorting.
RS-232 Pinout
RJ-45 to DB9 Serial Control Adapters
Refer to the RS-232 Conversion to DB9 and RS-422/485 Pinout Application Note located on the Savant Customer Community for more
information on RJ-45 to DB9 adapters.
NOTES:
–! CTS/RTS handshaking is supported for flow control based on the profile used in the configuration.
–! The Pro Audio 4 does not support RS-422/485
IMPORTANT!
If you are using RJ-45 to DB9 adapters not supplied by Savant:
–! Ensure that any wires required for communication/control are terminated within the adapter.
–! Ensure that all wires NOT required for communication/control are NOT terminated in the connector.
–! Ensure that the unused wires in the connector are cut to prevent them from shorting out, as they are still terminated in the RJ-45 connector on
the controller side.
