H COM port
This 9-pin male D-sub port is used to connect a Yamaha AD824 A/D converter. Control sig-
nals from a supporting device, such as the Yamaha DME32 Digital Mixing Engine or
Yamaha DM2000 Digital Production Console, can be transmitted via CobraNet’s Serial
Bridge. The COM port is an RS-422 serial interface, supporting cable runs of up to 1 kilo-
meter.
I TO COMPUTER port
This 9-pin male D-sub port is used to connect the NHB32-C to a COM port on a PC run-
ning NetworkAmp Manager. It’s an RS-232C serial interface, supporting cable runs of up
to 15 meters. The front panel USB port offers an alternative method of connection. The PC
port to be used for communication with the NHB32-C is set in NetworkAmp Manager.
J AES/EBU 1–4 I/O connectors
These four 25-pin female D-sub connectors are used to input and output up to 64 channels
of AES/EBU format digital audio. Each connector handles eight ins and eight outs.
AES/EBU inputs and outputs are assigned to CobraNet audio channels in NetworkAmp
Manager.
Cable Length & Switching Hubs
The maximum cable length for 100Ba-se-T Ethernet networks is 100 meters (2 kilome-
ters with fiber optic cables). However, depending on the type of cable, switching hub,
ACU16-C/NHB32-C’s workload, etc., reliable operation with this length of cable cannot
be guaranteed. In addition, although about three or four switching hubs can be con-
nected to a network, the actual number will depend on the efficiency of each switching
hub.
