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 B, Host Configuration Strings).
This 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, aft
er the timeout expires, any incomplete string
(any string not terminated by <CR>) is flushed from the device buffer.
Pen Parameters
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 s) corresponds t
o 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.
Conversion to Code 39 and Code 128
PowerScan™ M8500 Series Readers
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.
Overflow
This parameter generates a white space before the first bar and after the last bar of the code.
The selections are as follows:
narrow=space 10 times the minimum output pulse.
medium=space 20 times the minimum output pulse.
wide =space 30 times the minimum output pulse.
