Termination
The CC-16 zone controller uses a 2-wire RS-485 network to communicate with the ESP-88
sound processor. For optimum performance, the RS-485 network must be “terminated.” The
CC-16 includes built-in termination resistors which make it easy to terminate the network.
Termination is accomplished by setting DIP switches 1 and 2 to the ON position.
• In most cases, only one CC-16 zone controller – the last unit in the daisy chain network
(furthest away from the ESP-88) should have the termination set to ON.
• In a star topology, with the ESP-88 in the middle of two or more long runs, two units (the
two furthest from the ESP-88) should have the termination set to ON.
Note: Switch 3 (2X) should always be in the ON position.
