Advanced Operations

Optimization Parameters

The following 12 settings (A1 through D3) allow you to optimize your Imager’s perfor-

mance in your application environment. Try several settings to familiarize yourself with

the differences between the 12 options. You may find that the Imager’s default setting,

B3, is satisfactory for your application.

See the “Optimization Guide” for definitions of optimization terminology.

A1: Reads high and low density

symbols at high resolution in

near and far fields; spends 675

mS attempting to decode the

symbol; large region of interest

that extends beyond the symbol.

A2: Reads high and low density

symbols in near and far fields at

medium-high resolution in near

field and high resolution in far

field; spends 375 mS attempting

to decode the symbol; region of

interest that extends somewhat

beyond the symbol.

A3: Reads high and low density

symbols at low resolution in near

field and medium-low resolution

in far field, spends 250 mS

attempting to decode the sym-

bol; region of interest limited to

the symbol and its quiet zone.

B1: Reads high and low density

symbols in near and far fields at

high resolution in both fields;

spends 375 mS attempting to

decode the symbol; large region

of interest that extends beyond

the symbol.

B2: Reads high and low density

symbols in near and far fields at

medium-low resolution in near

field and medium-high resolu-

tion in far field; spends 250 mS

attempting to decode the sym-

bol; region of interest that

extends somewhat beyond the

symbol.

B3: Reads high and low density

symbols in near and far fields at

low resolution in both fields;

spends 250 mS attempting to

decode the symbol; small region of

interest limited to the symbol and

its quiet zone.

Use A1 if you are read-

ing a variety of symbol

densities and sizes, and

you are more concerned

with decode capability

than with decode speed.

Use A2 if you are read-

ing a variety of symbol

densities and sizes, and

you want dependable

but moderately fast

decodes.

Use A3 if you are read-

ing a variety of symbol

densities and sizes, but

you are concerned

mainly with obtaining

fast decodes.

Use B1 if you are read-

ing a variety of symbol

densities and sizes, and

you need reliable, mod-

erately fast decodes.

Use B2 if you are read-

ing a variety of symbol

densities and sizes, and

you want a balance of

decode reliability and

decode speed.

Use B3 if you are read-

ing a variety of symbol

densities and sizes, but

you want the fastest

available decode speed.
