Two programming tags must be scanned to enable this parameter: Hex E followed by 

Hex 0. 

RS-232 

RS-232 is used to connect the 7893 to almost any RS-232 type of communications device. This 

protocol uses 7-bit ASCII by default to send tag data to the device.

Protocol

The Good Read Tone programming mode selects the parameters for sounding a tone each time 

the 7893 successfully reads a bar code. It also controls the volume of the Not-On-File tone. 

This mode contains five shortcuts: A, B, C, D, and E. After entering this programming mode, 

proceed directly to a specific parameter by scanning the appropriate shortcut Hex tag. This 

eliminates the need to enter all parameters when only one needs changing. R 

Tone On/Off 

The Hex A tag selects the Tone On/Off programming parameter, which offers two options, On 

and Off. The Hex 0 tag turns the Good Read Tone off and the Hex 1 tag turns the Good Read 

Tone on.
