28 NHB32-C Network Hub & Bridge
ACU16-C & NHB32-C Owner’s Manual
Rear Panel
A Grounding screw
For electrical safety reasons, it’s important that the NHB32-C is grounded properly. The
supplied power cord has a three-pin plug, and if the ground terminal of the AC outlet is
grounded, then the unit will be grounded sufficiently through the power cord. If the AC
outlet does not provide a suitable ground, this screw must be connected to a good ground
point. Grounding is also an effective way to eliminate hum, interference, and other noise.
B AC IN connector
This connector is used to connect the NHB32-C to an AC outlet via the supplied power
cord. Connect the socket-end of the supplied power cord to the AC IN. Connect the
plug-end to a suitable AC wall outlet, one that conforms to the power supply requirements
stated on the NHB32-C’s rear panel. Use the supplied retaining clamp to secure the power
cord, preventing inadvertent disconnection.
C MIDI OUT/IN ports
These standard MIDI IN and OUT ports are used to connect MIDI devices for MIDI data
transmission via CobraNet’s Serial Bridge. Program Change and Control Change messages
can be transmitted over the Serial Bridge, however, it’s not suitable for time-sensitive per-
formance data such as MIDI Note On/Off.
D PRIMARY & SECONDARY CobraNet ports
These RJ-45 ports are used to connect the NHB32-C to the primary and secondary Cobra-
Net networks. Straight 100Base-TX CAT5 Ethernet cables should be used to connect the
NHB32-C to a CobraNet network. Use STP (Shielded Twisted Pair) cables to protect against
electromagnetic interference. If necessary, two CobraNet devices can be connected together
using a crossover 100Base-TX Ethernet cable. Straight and crossover cables are not inter-
changeable.
E WORD CLOCK 75Ω ON/OFF termination switch
This switch applies 75Ω termination to the WORD CLOCK IN. Normally this switch
should be set to ON when a wordclock source is connected to the WORD CLOCK IN. The
OFF setting is for use with wordclock source devices with special specifications.
F WORD CLOCK OUT BNC
This BNC connector outputs a wordclock signal.
G WORD CLOCK IN BNC
This BNC connector is for connecting an external wordclock signal. The wordclock source
is selected by using the wordclock source button on the front panel.
Wa r ning: Turn off all equipment connected to the NHB32-C before making any power con-
nections.
