22 Datalogic™ OPOS Service Object
• CapStatusUpdate – defaulted to 1, this indicates that the scale service is capa-
ble of supplying Status Update events as per the UPOS Live Weight 
Display
 description in the scale section of the UPOS spec.
• CapZeroScale – defaulted to not active. The Single Cable scale does not sup-
port host zeroing of the scale.
• LiveWeightInterval – default to 500; this is the poll rate in milliseconds that 
the scale service polls the scale for weight in the case of Live Weight Display 
enabled. 
•
Metric – defaulted to 0. This setting controls the type of Weight Request sent to 
the scale by the service; the default is English Weight Request. The user can set 
this to 1 to obtain Metric weights. 
CAUTION
• ZeroValid – defaulted to Active. When active, the service will deliver a stable 
zero weight as a valid weight to the host. When set to 0, the service will follow the 
pre-1.13 UPOS specification and not deliver zero as a valid weight (this setting is 
used by some customers to maintain a live weight display outside of the UPOS 
specification).
RS232Scale
• CapZeroScale – defaulted to Active, the scale service can zero the scale through 
the interface.
The user should never set this value below 250 msec.
The scanner/scale must be programmed to the same data type or weight 
requests will fail.
