In HDR shutter mode, the scanner captures profiles with alternating shutter value. A High- and a Low value
is defined by the software. The scanner captures profiles depending on the command sent before sending
the shutter values for High and Low shutter capture. The HDR feature is unique for M2-iLAN scanners.
Earlier models do not provide this feature.
Syntax:
<24h> = command: highest Bit not set!
Fro all following Bytes the highest Bit is set!
- - - - - - - - - - - - - - - - - - - - - - - - - -
<24h><80h> = deactivate
<24h><81h> = activate
- - - - - - - - - - - - - - - - - - - - - - - - - -
<80h> = each field is captured with different shutter value (= field switching mode)
<81h> = each second field is captured with a different shutter value (= full frame switching mode)
Example of a sequence:
B1 = shutter value 1
B2 = shutter value 2
Between both shutter values, for EACH field is switched
- - -
<24h><81h><80h><87h><D4h><80h><E5h> = B1=980 B2=101
- - -
Explanation of the syntax:
<24h><81h> = command "activate" // activate the HDR mode
<80h> = Definition "field switching mode"
<87h><D4h> = <Hi-Byte1><Lo-Byte1>
Shutter value Hi Byte: (X >> 0x07) | 0x80
Shutter value Lo-Byte: (X & 0x7F) | 0x80
... the value is = 980
<80h><E5h> = <Hi-Byte2><Lo-Byte2>
Shutter value Hi-Byte: (X >> 0x07) | 0x80
Shutter value Lo-Byte: (X & 0x7F) | 0x80
... the value is = 101

Ports are a part of the IP-address definition. When setting the working IP address, the port is defined
accordingly. As a factory default setting at MEL, we always use port: 3000.
You can use “any” port. Please consider, that some services use ports: Internet (http) = port : 80.
Port addresses above 1024 are used not very often, but there are some exceptions like VNC (uses ports
5000 … 6000). Ask your system administrator for restrictions and guidelines for port numbers.
