Element Description
SYSTEM NAME Alphanumeric name of the CM-1 module within CobraNet.
CM-1 FIRMWARE Firmware version of the CM-1 module.
LATENCY Latency setting for the CM-1 module. The settings 5.33 ms, 2.67 ms or 1.33 ms are available.
The number of bundles that can be transmitted / received by the CM-1 depends on the
selected latency:
5.33 ms: Up to 4 bundles (32 channels) can be transmitted and up to 4 bundles (32
channels) can be received simultaneously.
2.67 ms: Up to 4 bundles (32 channels) can be used (transmitted and/or received) in total.
1.33 ms: Up to 2 bundles (16 channels) can be used (transmitted and/or received) in total.
SAMPLE RATE Sample rate of all CM-1 modules. Preset to 48 kHz.
CONDUCTOR Green, if the CM-1 is the conductor (master) in the CobraNet, red, if another unit acts as
conductor within the CobraNet.
CONDUCTOR PRIORITY With a variety of units connected to a CobraNet, the unit that has the highest conductor
priority automatically becomes the conductor. When setting the priority of a CM-1 to ”0”
ensures that this CM-1 will never be the conductor in the network. Setting a CM-1’s priority
to ”255” ensures that this CM-1 will always be the conductor in a network.
ETHERNET Displays the Ethernet port (primary/secondary) of the CM-1 that is currently in use.
RX ACTIVE Green, if data is being received via CobraNet; otherwise red.
TX ACTIVE Green, if data is being transmitted via CobraNet; otherwise red.
RECEIVE An error has been detected during data reception via CobraNet.
TRANSMIT An error has been detected during data transmission via CobraNet.
GENERAL System fault within the CM-1 module.
AUDIO MUTE Audio transmission has been muted, because correct transmission cannot be guaranteed.
SYNC Synchronizing the DSP system to CobraNet is not possible.
WATCHDOG The CM-1 is being reset because of a hardware or software failure.
INTERFACE An error has been detected in the communication with the CM-1 interface.
