[. . . ] Please see the corresponding chapter CAN Interface on page 18. Switch on the 625TRSKK (via the power switch at the rear), the computer and any additional connected devices, if used. In order to avoid any pops or thumps that may damage your speakers, please switch on the connected devices (if used) in the following order: audio signal sources - mixer and/or recorders - (power) amplifiers. These devices should be switched off in the reverse order. Now start the IRIS-Net program on your PC. You will find a program introduction in the online help of IRIS-Net and the corresponding quick start guide in the menu: > . 3. 2 Installation of expansion cards The options for expanding the 625TRSKK controller through the use of expansion cards are explained in this chapter. The 625TRSKK can be equipped with expansion cards in different ways: · · 4 Slots (module slots) for the expansion of the system with analog/digital inputs (AI-1, MI-1, DI-1) or outputs (AO-1) 1 network module slot for the installation of a network module, e. g. CM-1 CobraNetTM Module NetMax 625TRSKK System Controller Owner's manual 15 Preparations · 1 DSP expansion module (DSP-1) for the expansion of the storage capacity and signal processing ATTENTION: It is essential to switch off the 625TRSKK if you want to install or change a module. You will find detailed instructions in the data sheet of the corresponding module. System expansion with analog/digital inputs or outputs There are four slots at the rear of the 625TRSKK which are intended to expand the systems with analogue or digital inputs or outputs. These slots have the marking AUDIO SLOT 1 to AUDIO SLOT 4 (see the figure on page 12). Any combination of the following types of expansion cards can be installed: · · · · AI-1 with 8 analog inputs MI-1 with 8 microphone inputs DI-1 with 8 digital inputs AO-1 with 8 analog outputs You can choose any slot for the installation of the expansion cards as the slot is automatically detected by the 625TRSKK after the installation. System expansion with a network module An audio network interface for CobraNetTM can be installed in the network module slot on the rear panel of the 625TRSKK. The connectors are connected in parallel and serve as input or output (for a loop-through) of the remote network. The CAN-bus has to be terminated with a 120 terminating resistance at both ends. Therefore, two terminating connectors CAN-TERM 120 are included with the 625TRSKK. Please plug these terminating connectors in the free RJ-45 connectors of the first and the last device at the CAN-bus. In addition to the CAN-bus, a balanced audio monitor signal is carried in the network wiring in order to monitor the input and output signals of all remote networks. This monitor bus makes it possible to monitor the input and output signals of all power amplifiers existing in the remote network via the software without the need for additional wiring work. At the 625TRSKK, the monitor bus can be gripped at a CAN connector (pins 7 and 8), it can be connected with an audio input and routed to a monitor box (e. g. ) for monitoring purposes.

If the network is only slightly extended, higher baud rates up to 500 kbit/s are possible. In case of larger extensions, the baud rate has to be lowered (to a min. The following table explains the relationship between baud rate and length of the bus or extension of the network. In principle, bus lengths over 1000 meters should only be realized with repeaters. Transfer rate (in kbit/s) 500 250 125 62, 5 20 10 Bus length (in m) 100 250 500 1000 2500 5000 Please see the CAN bus principles chapter on page 36 in the appendix of this document as well as the instruction manuals of the connected devices for further information on CAN bus (especially on system examples and performance specifications). NetMax 625TRSKK System Controller Owner's manual 19 Preparations USB connection The USB interface on the front panel of the 625TRSKK uses the USB 1. 1 standard. [. . . ] The CAN bus repeater accomplishes a signal processing and a reinforcement of the 36 NetMax 625TRSKK System Controller Owner's manual Appendix bus signals. The internal running time of the repeaters of approx. 150 ns corresponds to an extension of the bus over approx. · Creation of alternative network topologies By using one or several repeaters, not only the above-mentioned bus topology, but the creation of other network topologies are also possible.
