Program Run Disable (Prd) Mode - AMX DGX1600-ENC Hardware Reference Manual

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 the procedure is necessary, use NetLinx Studio (v4.0 or later) to resolve the communication and/or control problems with the
resident NetLinx program.
The PRD mode prevents the NetLinx program stored in the integrated Master from running during the Enova DGX enclosure's
power-up. Think of the PRD mode (ON) equating to a PC's "SAFE" mode setting. PRD mode allows you to power the unit, update the
firmware, and download 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.
To set the Config (Configuration) DIP switch (place 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 (places the integrated Master into PRD mode).

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.
If problems persist, contact technical support (see the following page).
