Standby/Monitor Mode
The control console immediately enters standby monitor mode at the conclusion of power-on scanning. The control console remains in
standby monitor mode until one of the two dials are rotated. If the dials are not adjusted for a period of 30 seconds, the control console will
revert to standby monitor mode.
In standby monitor mode, the control console repeatedly polls all units detected during power-on scanning. Unused motor addresses are
skipped, but the highest address must be within range of the control console model settings (25 or 125.)
