SE955 Integration Guide
Electrical
The SE923 chassis is electrically connected to Vcc while the SE955 chassis is electrically connected to
ground. The SE955 chassis must be isolated from the host Vcc and ground.
The SE923 scan engine operates at a Vcc of 3.3 to 5.0 VDC (±10%). The SE955-I100R/I300R/E100R scan
engines operate at a Vcc of 3.0 VDC to 3.6 VDC. The SE955-I105R/E105R scan engines operate at a Vcc of
3.2 VDC to 5.5 VDC.
The SE955 incorporates SSI that allows configuration of the scan engine. The following SSI features are
supported:
•
changing scan angle between 35° and 47°
•
selecting Aim or Scanstand modes
•
RSM reporting support
•
reflash loading to upgrade firmware.

Optical
When replacing an SE923 scan engine with the SE955 scan engine the following must be taken into
consideration:
•
Design of housing and scan engine must be reviewed by an optical-mechanical engineer.
•

Table 2-7
recommended minimum requirement.
•
Baffles designed for the SE923 may not be applicable for the SE955 due to the positioning of the
photo-diode.
•
The SE955 can be programmed to two different scan angles. It is recommended that the position of the
scan engine is set using the widest scan angle (47°). Setting the position for the narrow scan angle (35°)
and then changing the scan angle might cause clipping (internal reflection) of the laser beam against the
housing.
•
The SE955 scan engine does not require margin on either side of the bar code to decode.The 47° scan
line provides identical scanning performance to older scan engines with a scan line of 53°.

transmission, wavefront distortion, surface quality, coating, etc.). Window properties that satisfy the
recommendations for the SE923 scan engine automatically satisfy the recommendations for SE955 scan
engine.
Mechanical
When replacing an SE923 scan engine with the SE955 scan engine the following must be taken into
consideration:
•
Regulatory labels must reflect new VLD power.
•
Consider that existing cable flexes may not be compatible with the SE955 scan engine.
•
Consider mounting holes.
