→Description of signals
(Corrected logic levels in description of pin B7 (MF Chan Switch). Added note to description of pin B16 (Aux Y Axis) that it must only be driven when MF Channel Switch ≠ MF Mode.) |

* ''Delay Mode Control'' − Output on delaying timebase in horizontal slot A, connected to input on delayed timebase in horizontal slot B. >+3 V disables auto sweep in delayed timebase; 0 V enables independent timebase function. Grounded in amplifier plugins. | * ''Delay Mode Control'' − Output on delaying timebase in horizontal slot A, connected to input on delayed timebase in horizontal slot B. >+3 V disables auto sweep in delayed timebase; 0 V enables independent timebase function.
