Enova Digital Media Switchers - Hardware Reference Manual
Restoring the Factory Firmware Image and Factory Default Settings
1.
Verify that the Master is currently booting.
NOTE:
The Master is booting when the Program port Status and Input LEDs are ON (green and yellow respectively)
and the Output LED (red) is OFF.
2.
Press and hold the ID Pushbutton for 20 seconds or longer.
3.
Release the pushbutton.
Program Run Disable (PRD) Mode
IMPORTANT:
The information in this section is not applicable when the system is running under normal operating
conditions. The PRD mode should only be used if the resident NetLinx program is causing inadvertent communication
and/or control problems.
If necessary, use NetLinx Studio (v4.0 or later) to resolve communication and/or control problems with the resident NetLinx
program. PRD mode prevents the NetLinx program stored in the integrated Master from running during the Enova DGX
enclosure’s power-up.
PRD mode (ON) equates to a "SAFE" mode setting on a PC: it allows powering the unit, updating the firmware, and
downloading a new program, while circumventing any problems with a currently downloaded program.
Power must be cycled to the enclosure after activating/deactivating the PRD mode.
NOTE:
DIP switch #2 must remain in the DOWN (default) position.
Setting the Config DIP Switch To Place the Integrated Master in PRD Mode
NOTE:
The DIP switch is mounted with the ON position at the top (as indicated by the arrow on the left).
1.
Set the Position #1 DIP switch to ON to place the integrated Master into PRD mode (FIG. 30).
2.
Cycle power on the enclosure.
3.
Use NetLinx Studio (v4.0 or later) to resolve the communication and/or control problems with the resident NetLinx
system/project.
4.
Download the corrected system/project.
5.
Reset the DIP switch to OFF (places integrated Master back into Normal mode).
6.
Cycle power on the enclosure.
7.
Try communication and/or control again.
