11 - Cascade—Cascade connections11–2The master unit will check the connections,and check for the presence of other units inthe cascade which have had their IDs setcorrectly. The screen below will be shown iftwo correctly-congur ed and connectredslaves are discovered in the cascade.6 Press ENTER to continue with the cascadeoperations, or, if the number of slaves hasbeen wrongly reported, press a cursor key tocancel, check connections and settings, andre-try.If no slaves are discovered by the master, thefollowing screen appears:7 When ENTER is pressed (in 6 above), theslave units’ CLOCK indicators will go out, asthe slaves lock their clocks to that of the mas-ter unit.After the clocks have been set, other internalsettings are communicated between the mas-ter and slave units. Do not try to add orremove units from the cascade. The followingmessage appears if a cascade connection isbroken or a unit is removed (via software)from a cascade while this negotiation is tak-ing place:When turning on a previously-congured cascade ofunits, make sure that the master unit is always turnedon last.It is not possible to turn the cascade function off onany unit or to turn the power off on a cascaded unitwhile the cascade is in use. If the power to a slaveunit is turned off accidentally, turn the slave offagain, and restart from step 5 (turning the masterunit’s cascade off and on again to re-recognize theexistence of the slaves).The top on-screen button in the DIGITAL I/O CASCADE screen, shown below, is used toturn the cascade on or off. If this is set to OFF , theunit is described as being out of the cascade, even ifit is physically connected as part of the chain.NOTEDo not attempt to turn the cascade on or offwhile the initial “negotiation process” is takingplace, as described above. If an attempt ismade to do this, the cascade setup must bere-started from the beginning. If the cascadefunction of a slave unit is turned off while thecascade is in operation, the cascade setupprocess must be re-started from step 5above.Every time the units in a cascade are powered off,their cascade status and IDs are memorized. How-ever, so that the master can negotiate the cascade sta-tus, it is important that the slave units are turned onrst, allo wing the master to recognize the slave unitswhen the power is turned on. The cascade slavesshould be recognized, and ENTER pressed to con-tinue using the cascade.11.1.1Selecting busses for cascadeIn the CASCADE screen of a slave unit, it is pos-sible to select the following for cascade through thechain, or to make them local to the unit:• output busses 1 through 8• Aux sends 1 through 4As explained above, Aux sends 5 and 6 may be usedwith the individual effect processor of each unit, pro-viding greater e xibility in effect processing in alarger system.When a buss or Aux send has a check mark beside it(4), the buss or send is passed through from the unitto the master unit. In addition, the summed eight out-put busses are output in parallel from all slave unitsthat add their buss to the cascaded summed buss, aswell as the master unit.
