A
USB port
This USB port is used to connect the ACU16-C to a USB port on a PC running Net-
workAmp Manager. The rear panel TO COMPUTER port offers an alternative method of
connection. The PC port to be used for communication with the ACU16-C is set in Net-
workAmp Manager.
B
UNIT ID switch
This switch is used to set the unit ID of the ACU16-C. Each ACU16-C on the network must
be assigned an exclusive ID from 0 to 15. The following table shows how the switch mark-
ings correspond to unit IDs 0 through 15. The switch can be set by using either a small
flat-bladed screwdriver or a Phillips screwdriver.
C
NETWORK STATUS indicators
LINK: This indicator lights when the ACU16-C has a valid connection to a CobraNet net-
work. If a link cannot be established, the CONDUCT and ERROR indicators light instead.
CONDUCT: This indicator lights when the ACU16-C is the CobraNet Conductor (i.e.,
wordclock master and arbitrator for the entire network).
ERROR: This indicator lights when a CobraNet link cannot be established, and flashes
when a CobraNet interface error occurs.
D
POWER ON/OFF switch
This push switch is used to turn on the ACU16-C. To prevent loud clicks and thumps in
your speakers, turn on your audio equipment in the following order (reverse this order
when turning off)—sound sources, A/D converters, mixers, network equipment,
NHB32-C/ACU16-C, D/A converters, power amplifiers.

Note: The ACU16-C must be turned off before setting the unit ID. Make sure that each
ACU16-C is assigned an exclusive ID. Assigning the same unit ID to two or more ACU16-Cs
will produce unpredictable results.
Note: Use a screwdriver that’s appropriate for the size of the slot in the switch. Using a screw-
driver with too big a handle, or a screwdriver with too small a tip, may damage the switch.
Note: If a system error occurs, the LINK, CONDUCT, and ERROR indicators flash simulta-
neously. This type of error can be caused by an incorrect device setting or a faulty ACU16-C.
See “System Errors” on page 37 for more information.
