Utility/Diagnostic Functions

Safe Mode Switch

Location of Safe Mode switch: The front panel has a small access hole on the left side, just left of the Power indicator. It is not labeled to help prevent accidental use. The Safe Mode switch can be operated by using a paper-clip (or similar item) inserted into the access hole and pushing.

Safe Mode: Use if the BASIS 922dz becomes inoperable (or behaves in completely unexpected ways) after updating firmware.

If the BASIS 922dz operates in an unexpected way or is not responding to any communications after a new firmware file is uploaded to it, it is likely the file was corrupted during transfer. If this occurs, there is a “backup” program in the BASIS 922dz that will enable you to communicate with it.

How to put the BASIS 922dz into Safe Mode:

1- Turn off the power to the BASIS 922dz by unplugging it from the AC outlet.

2- Depress the safe mode switch and keep it depressed while plugging the unit back in (power on).

3- The BASIS 922dz is now in “safe mode”. You may release the switch.

You should now be able to re-establish limited TCP/IP communications with the BASIS 922dz. Once communication has been re- established, the file transfer can be tried again or the old application file used until the source of the data transfer problem can be found. Also, QSControl.net WILL NOT communicate with the BASIS 922dz if it is in “safe mode”. You may communicate only using TFTP, Telnet, or RS-232.

RS-232 Serial Port I/O Interface

The RS-232 connector on the rear panel is used as a serial port input/output (I/O). This I/O port is used for accessing Ethernet/IP settings, stand alone control capabilities, system “health” data, firmware version information and other related data.

Should any system problems arise, the data that may be accessed through this interface can help to track down the problem. The most common items that might be used are “Display Network Settings” and “Enter Network Setup”. Many of the remaining selec- tions would typically be used for troubleshooting purposes along with a QSC technical representative prompting you to access par- ticular menu items so the data can be interpreted.

Connection is made using a normal serial cable between your computer’s serial port and the RS-232 port of the BASIS 922dz. Once properly connected, a “dumb-terminal” program (such as Hyper Terminal, a widely used version on most Windows-based PC’s) is started and communication established between the PC and the BASIS 922dz.

Following is the basic procedure for starting up Hyper Terminal, naming the connection, specifying the communications settings and an example of “what you should see” for a text-menu once the communications link has been established. If programs other than Hyper Terminal are used, you will need to follow your software’s instructions for establishing communications through your PC’s COM (serial) port.
