RS-232 Considerations

In RS-232 Batch Cable - Detect mode, the HE40T will detect if it is connected to a powered serial cable, and will send the data. If a powered serial cable is not connected or if the power adapter is not connected to the serial cable, the HE40T will buffer the data. When the HE40T is then connected to a powered serial cable, the data will automatically upload.

In RS-232 Cabled - No Power mode, the HE40T will behave as if it is always connected even though the serial cable is disconnected or the power adapter is unplugged. Scanned data will be sent, regardless of connection status. Data scanned in Cabled mode will be lost if the HE40T is not connected to the serial cable. It will not buffer the data, unless Send & Store mode has been enabled.

Note: If you are in RS-232 Cabled-No Power mode, when you place a reader in a charger, the reader will behave as if it is being cabled, and download the data. THE DATA WILL BE ERASED FROM MEMORY. To disable this feature, scan the RS-232 Cable - Detect code.
