6. CC-16, RS-232, and ESPLink connections
CC-16 Connector
The CC-16 connector is an RS-485 network connection for use with
Bose CC-16 zone controllers. Using the supplied Phoenix Contact
®
3-pin
labeled connector, up to 15 CC-16 zone controllers can be networked to
control the ESP processor or any device on the Bose
®
ControlSpace
®
control network. An external power supply is required. Note that in
addition to wiring the A and B terminals, it is highly recommended to
connect the ground terminal from the ESP processor to each CC-16 zone
controller. The maximum distance from ESP processor to any CC-16 is
2000 feet (610 m).
RS-232 Connector
The RS-232 connector provides a DB-9 male connector (type DTE) for
communication between the ESP processor and other serial-controlled
devices including third-party control systems.
Figure 7. RS-232 Panel Connector Pinout
The default serial port settings are 115,200 baud, 8-bits length, 1 stop bit, no parity, and no flow control. If required these settings can
be changed using ControlSpace
®
Designer
™
software.
The document ControlSpace
®
Serial Control Protocol (downloadable from pro.Bose.com) outlines all supported command strings and
functions available to control/query Bose ESP processors and PowerMatch
®
power amplifiers.
ESPLink Connector
The ESPLink connector provides a low-latency method for transporting
up to 8 channels of uncompressed audio to PowerMatch
®
amplifiers.
For use with standard optical (TOSLINK
™
) cables.
Figure 8. Using ESPLink to distribute audio to PowerMatch amplifiers
An ESP-880/1240/4120 processor can serve as a
centralized input routing/mixing point for simplified audio
distribution to one or more ESPLink-equipped PowerMatch
amplifiers when installed in the same rack.
