6 If connecting the Engine using an RS-232 interface, all communication parameters
between the imager and terminal must match for correct data transfer through the serial port using
RS-232 protocol. Scan the RS-232 interface bar code below. This programs the Engine for an
RS-232 interface at 115,200 baud, parity–none, 8 data bits, 1 stop bit, and adds a suffix of a CR
LF.
7 Verify the engine operation by scanning a bar code from the Sample Symbols in the
back of this manual. The engine beeps once when a bar code is successfully decoded.
Reading Techniques
The engine has a view finder that projects a bright red or green aiming beam that corresponds to
the engine‟s horizontal field of view. The aiming beam should be centered over the bar code, but
it can be positioned in any direction for a good read.
Linear bar code 2D Matrix symbol
The aiming beam is smaller when the engine is closer to the code and larger when it is farther
from the code. Symbologies with smaller bars or elements (mil size) should be read closer to the
unit. Symbologies with larger bars or elements(mil size) should be read farther from the unit. To
read single or multiple symbols (on a page or on an object), hold the engine at an appropriate
distance from the target, send a trigger command, and center the aiming beam on the symbol. If
the code being scanned is highly reflective (e.g., laminated), it may be necessary to tilt the code
+5° to prevent unwanted reflection.
