’Online’ Commands for BCL 80 with Oscillating Mirror
Transmit parameters
Attention!
The ’PT’ command lets you change the parameter set in a way that may render it useless.
Make sure that you only use parameter numbers and ranges that have been described here.
Command
’PT’
Description
This command permits the programming of arbitrary reading areas. They can be
selected during operation. The scan area can be adapted to any application.
Parameter
PT000xxxyy
x and y are variables that are to be replaced with the actual input.
’xxx’ defines the parameter number (384, 386, 387, 388, 389)
’yy’ defines the range for the parameter (in hexadecimal)
384 = mode of mirror oscillation (00h … 02h)
00 (mode 0) when activated the oscillating mirror moves from start to
stop position
01 (mode 1) when activated the oscillating mirror moves from start to
stop position and back
02 (mode 2) when activated the oscillating mirror moves permanently
between start and stop position
386 = time interval for forward movement (02h … 5Fh)
selectable in 50 ms steps, e.g.
03 corresponds to a forward movement time of 150 ms.
02 is the smallest value = high osc. frequency (5 Hz)
5F is the highest value = low osc. frequency (0.1 Hz)
387 = time interval for reverse movement (02h … 5Fh), as 386.
388 = start position of the oscillation movement(00h … 5Fh)
00 corresponds to +15° (see
Chapter 4.3.3 "Reading Fields")
389 = stop position of the oscillation movement (00h … 5Fh)
5F corresponds to -20° (see
Chapter 4.3.3 "Reading Fields")
Acknowledgement no
Example
Input = 'PT00038402' (sets mirror into mode 2)
Input = 'PT0003860A' (forward movement time 0Ah = 10 x 50 ms)
Input = 'PT00038704' (reverse movement time 04h = 4 x 50 ms)
Input = 'PT00038804' (start position 04h)
Input = 'PT00038953' (stop position 53h)
Note!
To change the default values, you may transmit one or more parameters in a string online
to the scanner. A subsequent soft reset (’H’ command) activates the new settings.
