What is the RS232 command to retrieve my product's temperature status?
The RS232 command to retrieve the projector's temperature status is WLEVEL?. This command can be added to a Crestron or AMX command string, or can be used in a Windows HyperTerminal session connected directly to a projector's DB9 serial port using a NULL serial cable or a NULL serial adapter attached to a straight-through PC serial cable. If you are using a laptop with only USB ports, you will need to use a USB-to-DB9 serial adapter with an assigned com driver. Select the com driver to use in HyperTerminal.
To set up HyperTerminal, do the following:
- Click Start or , and select Programs or All Programs, then Accessories and Communications.

- Click File, then Properties, and select the Settings tab.

Code Description T01 Normal Temp (Low) T02 Normal Temp (Middle) T03 Normal Temp (High) T04 High Temp alarm T05 Hight Temp Error (Overheating)
- When you are ready to exit HyperTerminal, click File and Exit.
