IBM USB Scale Default Response Status

Parameter #
1286
A scanner configured with a scale sends a 2-bit scale to the IBM USB Point of Sale (POS) system as the default setting. This parameter enables a user to program the scanner or scale to send either 2-byte scale status, or a 3-byte scale extended status.

*2-byte Scale Status

Extended Scale Status Disabled: The 2-byte scale status sent to the IBM POS consists of the information shown in Scale Status Byte 0 and Scale Status Byte 1.
