The CAB 8o device provides analog exit points for audio signals. The CAB outputs a single network channel with its 8 analog outputs. This network channel can be transmitted by either a CAB 8i, or a CobraNet Interface using the CobraNet Output Device. The CAB also has 8 control voltage inputs, 8 TTL outputs, and 8 relay outputs.
Enter the network bundle that the CAB 8i should be receiving from. Bundles 1-255 are multicast (broadcast to all) and 256-32767 are unicast (one-to-one broadcast). Unicast (256-32767) bundles are recommended to prevent network congestion.
LED on indicates that the CAB is currently receiving the specified network bundle.
LED on indicates a valid control link between the MediaMatrix frame and the CAB.
The 4 digit hex id of the CAB. This needs to match the switch settings on the front of the CAB, and also must be unique for the whole system. Acceptable values are 0001 - FFFF. This setting has nothing to do with the bundle assignment (other than to identify the CAB that the "Network Bundle" control applies to).
Valid Hardware ID
LED on indicates that the Hardware ID entered is within the valid range of available Hardware IDs (0001 - FFFF).
The Mute All switch mutes all individual outputs by opening relays. When on, the Mute All switch will indicate a muted condition, however the individual channel mutes will not indicate.
Mutes the analog output of the CAB. This is not a complete mute however, but an attenuation of around -100 dB. This is due to the fact that the overall mute for the CAB 8o opens relays and thus does completely mute.
Sets the analog gain for a respective bundle.
Full Scale Output
The analog output setting for a respective channel. This setting corresponds to a full-scale digital signal.
Control Voltage I/O (CV)
When pressed, toggles the state of the TTL output on the CAB (0 or 5 Volts DC).
Toggles the Relay Output of the CAB.
The control input signal after scaling according to the Min and Max settings in "CV Cal." See Control Input Calibration for information on setting up control inputs.
CV Calibration (CV Cal...)
Calibration is usually necessary before using the CV inputs to control other controls within MWare. The normal procedure is to set the Min and Max values to the actual real-world control you will be using before attempting to adjust virtual controls within MWare.
NOTE: If you want the action of a control linked by a control group to the CV Input control, reverse the entries in the Max and Min text blocks. You'll then get the opposite action.
Raw Input (green text blocks)
Shows the raw control input signal before scaling. The analog control inputs have an 8 bit resolution.
Max (pink text blocks)
Sets the Raw Input value which will produce a scaled value of 255. Even if the Raw Input exceeds the Max setting, the scaled Input will not go above 255.
When pressed, the current Raw Input value is copied to the Max setting.
Min (blue text blocks)
Sets the Raw Input value which will produce a scaled value of 0. Even if the Min setting exceeds the Raw Input, the scaled Input will not be allowed below 0.
When pressed, the current Raw Input value is copied to the Min setting.
