Both ends of a CAN-bus need to be terminated with 120. termination-plugs. The maximum bus-length depends on the actual data transfer rate, the kind of data transfer cable being used, as well as the total number of participants on the bus. The following table shows the most essential coherencies for CAN-networks consisting of up 64 participants: Bus Length Cable for data Transmission Termination max. Data Transfer Rate Resistance per Unit Length Cable Diameter 0 ... 40 m < 70 m./m 0.25 ... 0.34 mm. AWG23, AWG22 124 . 1000 kbit/s at 40 m 40 ... 300 m < 60 m./m 0.34 ... 0.6 mm. AWG22, AWG20 127 . 500 kbit/s at 100 m 300 ... 600 m < 40 m./m 0.5 ... 0.6 mm. AWG20 150 . ... 300 .* 100 kbit/s at 500 m 600 ... 1000 m < 26 m./m 0.75 ... 0.8 mm. AWG18 150 . ... 300 .* 62.5 kbit/s at 1000 m * With longer cables and many participants on the CAN-bus, termination resistors with higher impedance than the specified 120. are recommended to reduce the ohmic load of the interface drivers and therefore the voltage drop between the two cable ends. The following table is meant for first assessment of necessary cable diameters for different bus lengths and bus-participant numbers: Bus Length Number of Appliance on the CAN-Bus 32 64 100 100 m 0.25 mm. or AWG24 0.34 mm. or AWG22 0.34 mm. or AWG22 250 m 0.34 mm. or AWG22 0.5 mm. or AWG20 0.5 mm. or AWG20 500 m 0.75 mm. or AWG18 0.75 mm. or AWG18 1.0 mm. or AWG17 Additionally, the length of branch lines – for participants that are not directly connected to the CAN-bus – is also of importance. For data transfer rates of up to 125kbit/s, the maximum length of a single stub cable should not exceed 2m. For higher bit rates a maximum length of only 0.3m is still permissible. The entire length of all branch lines should not exceed 30 m. General Note: As long as only short distances (up to 10m) are concerned, common RJ-45 patch cables with 100. characteristic impedance (AWG 24 / AWG 26) can be used for the cabling inside of a rack- shelf system. The previously outlined guidelines for network cabling are mandatory as far as the rack-shelve interconnection or fixed installations are involved. MAINS OPERATION & RESULTING TEMPERATURE MAINS OPERATION The following tables allow determining power supply and cabling requirements. The values of the column „Max. Output @ 4.” are relevant for “normal” operation. These values are based on operating the power amplifier with VDE-noise at 1/8 of the maximum output power, which approximately equates the load of the power amplifier being operated with a music signal at maximum volume possible, without noticeable clipping. RESULTING TEMPERATURE INSIDE THE POWER AMPLIFIER The power drawn from the mains network is converted into acoustic output power to feed the connected loudspeaker systems & heat. The difference between drawn power and dispensed power is called leakage power or dissipation (Pd). The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted using appropriate measures. The following table provides auxiliary means for calculating the temperatures inside of a rack-shelf system/cabinet and the ventilation efforts necessary. The column “Pd” lists the leakage power in relation to different operational states. The column “BTU/hr” lists the dispensed heat amount per hour.
