Omnidirectional Scan Pattern
The high-speed rotating omnidirectional scan pattern provides aggressive performance on 1D bar codes because
there are no “holes” in the pattern. This ensures fast throughput at the point of activity and the ability to read 1D
symbols in 360
o of rotation, eliminating the need to orient the bar code in the field of view.

High Density Single Scan Line Scan Pattern
The high density single scan line appears as a "mini" raster and scans multiple areas of
1D codes to swiftly and accurately capture data on poorly printed and damaged bar codes.

Scan Angle Selection
The Symbol MS1204FZY and MS954 scanners support two pre-set scan angles (see each scanner’s technical
specifications)
.
Selecting Scan Angle via SSI
To use SSI to select the scan angle, issue the SSI PARAM_SEND command with the NUM_SCAN_ANGLE (191)
parameter number. This is set to the default angle (182), or can be set to the alternate angle (181). See the Simple
Serial Interface (SSI) Programmer’s Guide (p/n 72-40451-xx) for more information.
Selecting Scan Angle via Parameter Bar Code
The scan angle can also be set by scanning a parameter bar code (see Scan Angle on page 10-12 ). Once the
parameter bar code is scanned, that scan angle setting is retained.
Operation in Blink Mode
The scan angle during Blink Mode is determined by the scan angle system parameter.
