IRIS-Net
In addition to the CAN-bus data signal, network cabling also carries the balanced monitor audio signal for monitoring
the power amp inputs and outputs. This monitor-bus allows software-controlled monitoring of the input and output si-
gnals of all power amps that are included in the remote network, without the need for additional wiring. This balanced
line level audio signal is present at the UCC1's XLR-type MONITOR Output connector. Typical uses include connecting
it to a spare input of a mixing console or an active monitor speaker so that an engineer can easily monitor the audio
signal at the input or output of any amplifier on the network. The CAN-bus standard provides several different data
transfer rates, with the data rate being indirectly proportional to the bus cable length. Small networks allow baud rates
up to 500 kbit/s. For very large networks reducing the baud rate (minimum 10 kbit/s) is necessary. The following table
indicates the relation between baud rate and bus length or in other words network dimensioning:
Data transfe rrate
500 kbit/s
250 kbit/s
125 kbit/s
62,5 kbit/s
20 kbit/s
10 kbit/s (Default)
