Rear Panel

AGrounding 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.

BAC 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.

CMIDI 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.

DPRIMARY & 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.

EWORD 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.

FWORD CLOCK OUT BNC

This BNC connector outputs a wordclock signal.

GWORD 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.

Warning: Tu rn off all equipment connected to the NHB32-C before making any power con-

nections.
