Controls

id

A four digit hexadecimal number between 0000 and FFFF (0000 is off). This number uniquely identifies the CAB on the network. It is specified on the front panel of the CAB hardware using rotary switches.

When a valid number is entered, the Link LED will be lit and the LEDs on the CAB will turn from Hardware IDs to meters.

Link

Lit (green) when a link is established between NWare and the device across the network.

Receivers

Receiver / RX

Lit (green) when data is being received on one or more of the subchannels in the bundle.

Bundle

The bundle number that identifies a group of up to eight sub‑channels.

Each bundle can manage between 1 and 8 channels. The range is 0 to 65,535 (0 is off). For multicast bundles, the number must be in the range 1 to 255. For unicast bundles, the number must be in the range 256 to 65,279. Numbers in the range 65280 to 65535 are reserved and cannot be used.

Sub-Channel Mapping 1-8

Boxes for each sub-channel in the bundle. In these boxes you specify the numbers (1-32) of the CM-1 outputs you want to transmit.

Tip: Values in the Sub-Channel Mapping boxes may be changed on a dynamic basis. This allows any hardware channel number to be mapped to any bundle sub-channel(s) at any time, greatly expanding signal routing flexibility. However, only users familiar with advanced CobraNet practices should use this feature.

Priority

The priority of the group of sub-channels.

Tip: You can use the priority setting to implement a redundancy system for transmitters. Specify the priority for a row and then, on a second device, specify the same settings, but use a lower priority. If the transmission of the first row fails, the lower priority row will be transmitted.

Mute

Mutes the channel.

Output (dBu)

Output scale. This can be set to 6 dBu, 12 dBu, 18 dBu and 24 dBu.

The levels indicate a maximum setting and allow the user to shift the available dynamic range for flexibility in matching the input sensitivity of the power amplifier unit. When the gain is at 0 dB, the input sensitivity is determined solely by the Output (dBu) setting.

Gain

Sets the amount of amplification or attenuation to be applied to the signal. The valid range is -95.5 to +30.5 dB.

Note: If you turn down the gain to a very low level, for use with a microphone, for example, this can cause distortion in the output signal. We therefore recommend that you leave the gain set at a relatively high level and control the output level using a separate device.
