20. User locks Front panel Programming Lockout (during power down cycle only)
(Front panel or RS-232 port) (Unlocked mode only)
Programming lockout is to lock all programming functions so that they are not able to
be accidentally re-set to some unintended setting during normal operation. (To make a
system change requiring re-programming, lockout is unlocked and then re-locked after
making the change.)
User input:
User presses front panel Power button while holding Mon/Proc
button down. Addressable through RS-232 port also – see specific
section for command structure.
Indication: No

Status:
Unit does not allow any programming modes (Triggers, or trigger
timing, Unity gain, input mode, input disable or enable, and input
offset) while locked
21. User Powers down to Stand-by mode (Front Panel, remote control)
If trigger functions are used to signal the remote power amplifiers to be turned on the
preamplifier should not be left powered up when not in use, and power down to
standby condition is required to await power on command.
User input:
User presses Power button, either on front panel or remote control
while the unit is in power-on mode, or sends a discrete power off
signal from external remote.
Indication:
The display turns to double dash. All other indicators are turned off.
Status:
The unit immediately begins power down and releases output relays
to closed position. Last used input selection, phase, channel balance
unity gain processor loop settings, countdown and balance
suppression are all saved in memory for next power-up.
22. User re-powers after power down command (Front panel or remote wand only)
