Front Panel

1. HARDWARE BASE ADDRESS SWITCHES 4-position rotary switches for setting

the hardware base address (ID). Located behind removable front panel for tamperproof

settings.

2. FAULT LED Illumination of the Fault LED indicates an unexpected condition within

the CobraNet interface. Some fault conditions will also light the RX Error and/or TX

Error LEDs; this is to give more specific indication if the unexpected condition is in the

receive or transmit processes. The errors are reported by a series of flashes.

3. CONDUCT LED Indicates the CAB 4n is an active Conductor on the CobraNet

network. Only one Conductor is allowed per network.

4. LINK LED Indicates the physical layer connection has been established between the

CAB 4n and the network switch. This function is duplicated in the software control panel

(available via the

block in NWare).

5. RX LED Indicates the presence of data being received into the CAB 4n from the

CobraNet network.

6. TX LED Indicates the presence of data being transmitted from the CAB 4n onto the

CobraNet network.

7. HARDWARE BASE ADDRESS INDICATORS or AUDIO METERS. These LEDs

have a dual purpose.

a) Before a valid CobraNet control connection has taken place, these indicate the

hardware base address (ID). They are used in conjunction with the hardware base

address switches (see item #1 above) to set the Hardware ID, which allows NWare

and the NIONs to communicate with, and control, the CAB 4n.

b) Once the CAB 4n is being controlled by the NION software, these become peak

reading LED ladder displays, indicating audio input/output levels in the analog

domain. Signal level is displayed after the adjustable gain stage and before the A/D

converters.

8. POWER LED Indicates that the CAB 4n is powered from an AC mains power source.
