Resetting the Switcher
The switcher can be reset to the factory defaults via the front panel, USB, or RS‑232.
The reset button on the front panel is a small recessed switch that allows the user to put
the switcher into two different reset modes. The PVS 405D switcher reset modes are:
• Mode 1: If the Reset Button is held down while the switcher is being powered up, the
switcher reloads its base factory firmware instead of any newer code that was loaded
after it shipped.
• Mode 2: If the user holds the reset button down for 10 seconds and the power LED
blinks once, the switcher will reset its settings back to factory default condition (Zxxx
reset). Firmware will send out unsolicited response via RS‑232/USB
Executive Mode (Front Panel Security Lockout)
To prevent accidental or unauthorized changes to settings, the PVS switcher has a front
panel security lockout (executive mode) that limits access to front panel controls.
When executive mode is active, all front panel functions are locked except the reset
button. This mode can also be turned on or off via a Simple Instruction Set (SIS)
command.
All the input LED indicators should light up for one second to indicate that executive mode
has been enabled or disabled.
To turn executive mode on or off via the front panel:
1. Press and hold input selection button until all input LEDs blink (approx. 10 seconds).
2. Release the button. The LEDs extinguish except for the currently selected input. The
switcher has enabled or disabled the executive mode.
