4.1.4 RX Timeout
When the RS-232 interface is selected, the Host can be used to configure the device
by sending it command strings (see appendix A).
T
his parameter can be
used to automatically end data reception from the Host after
the specified period of time.
If no character is received from the Host, after the timeout expires, any incomplete
string (any string not terminated by <CR>) is flushed from the device buffer.
4.2 PEN PARAMETERS
4.2.1 Minimum Output Pulse
This parameter sets the duration of the output pulse corresponding to the narrowest
element in the barcode. In this way the code resolution is controlled by the signal sent
to the decoder, independently of the physical resolution of the code read.
The shortest pulse (200 μs) corresponds to a high resolution code emulation and
therefore a shorter transfer speed to the decoder (for decoders able to work on high
resolution codes). Likewise, longer pulses correspond to low resolution code
emulation and therefore a longer transfer time to the decoder.
4.2.2 Conversion to Code 39 and Code 128
When using these readers it is possible to choose between converting the decoded
codes into either Code 39 format or Code 128 format. It is not possible to disable
conversion.
