Slot <number>: AudioScience 5416


Link	Lit (green) when a link is established between NWare and the device across the network.
Conductor	Lit (yellow) when this unit is the CobraNet Conductor. Note: Currently, it is not possible to specify the conductor priority manually.
Fault	Lit (red) when a fault condition, e.g. thermal or short circuit, has been detected.
Err Count	The number of errors recorded by the device. Note: Errors are recorded when certain routine operations are carried out, including disconnecting cables and rerouting.
TX	Lit (green) when data is being transmitted.
TX ERR	Lit (red) when an error occurs during data transmission.
RX	Lit (green) when data is being received.
RX ERR	Lit (red) when an error occurs during data reception.
Transmitters
Transmitter / TX	Lit (green) when data is being transmitted 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 corresponding hardware channel number 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.
Num Chan	The number of audio channels to be included in the bundle. The Num Chan setting, which has a default of 8, controls how many audio channels are sent in a bundle. The value should be set to the number of contiguous channels that will be used, as defined in the Sub-channel Mapping boxes. If Num Chan is set to a value that is greater than the number of channels used, then the bundle will be larger than necessary and will result in wasted bandwidth and processor time. Unused channels with a value of 0 are represented in the bundle by header data only (and no audio data will be included). If the bundle contains subchannel numbers that are not used, they will be sent as full audio channels and consume 1 Mbit of bandwidth per channel.
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.
Unicast Mode	Controls how a bundle is transmitted onto to the CobraNet network. There are several modes of operation: Unicast - the bundle is sent directly to only one receiver. Multicast - the bundle is sent to all receivers, even if it is not required by the receiver. This mode will always consume bandwidth at all nodes. Multi-unicast - up to four copies of the same bundle are sent unicast to up to four different receiving nodes. Specify Always (the default) to always use unicast, or 1, 2, 3 or 4 to specify the number of receivers for the bundle. If there is only one receiver for a transmission, unicast will be used automatically. If Unicast Mode is set to 1 or greater, unicast will be used unless the number of receivers on the network for a particular bundle number is greater than the value of Unicast Mode; in this case, bundles will be sent as multi-unicast until the number reaches the value of Max Unicast. Note: If you specify a bundle number that is less than 256, multicast will always be used and the Unicast Mode setting will be ignored.
	Examples
	Unicast Mode is set to Always. Max Unicast setting is ignored. There are four receivers set to receive the bundle. The bundle will always be sent multicast because the number of receivers for the bundle is greater than 0.
	Bundle number is greater than 256. Unicast Mode is set to Always. Max Unicast setting is ignored. There is just one receiver set to receive the bundle. The bundle will be sent unicast because the number of receivers is less than 2 (and the bundle number is greater than 256, so multicast mode is not enforced).
	Unicast Mode is set to 2. Max Unicast is set to 2 or greater. There are four receivers set to receive the bundle. The receiver bundle count is 4, which is greater than 2, so the bundle will be sent multicast.
Max Unicast	The number of duplicated bundle transmissions (rows with identical settings and the same bundle number) that will be sent in multi‑unicast mode before true multicast is used.
Receivers
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 corresponding hardware channel number you want to receive. 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.

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.

Comm port	The comm port and serial protocol to use for data transfer.
Bits per sec	The baud rate (speed) for data transfer.
Data bits	The number of data bits in each character. Baudot uses 5, true ASCII uses 7. We recommend using 8, as this can be used for any type of data.
Parity	Specifies that an extra bit is to be included in the data transmission. This can be used for error detection.
	none	No parity bit is sent. Error detection is handled by the communication protocol.
	even	The parity bit is set to 1 if the number of ones in the set of bits is odd, therefore making the number of ones even.
	odd	The parity bit is set to 1 if the number of ones in the set of bits is even, therefore making the number of ones odd.
	mark	Parity bit is always set to the mark signal condition (logical 1).
	space	Parity bit is always set to the space signal condition.
Stop bits	Bits sent at the end of every character to signify the end of the character in the data transmission. Normally, 1 stop bit is used.
Rear mode	The operating mode for a data port that supports more than one mode. For example, RS-422 or RS-485.

Served	The number of IP addresses that the BOOTP server has allocated to devices on the network since the nControl unit was last booted.
Failed	The number of requests for IP addresses that were unfulfilled. A failure can occur when all the IP addresses in the range have already been allocated and a further request for an IP address arrives. The list of available IP addresses changes when addresses are allocated to devices and when addresses are reclaimed from devices when they are no longer required.
Message	A status message indicating that a task has been completed successfully, or that a problem has occurred.
