If an auxiliary scanner is connected via SSI over RS-232 for Zebra scanners, HID Keyboard for non-Zebra scanners, or standard RS-232, and the Send Raw Decode Data option is enabled, the host scanner transmits decode data with the code type set by this parameter. The default is value 1 (Send Unknown as Code 39).
If the device is set to any IBM host type, Auxiliary Scanner Decode with Unknown Type is not applicable.
