Note: 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.
