METTLER TOLEDO PS Shipping Scale: Technical Manual

(08/09) Appendix B-2

Power

The PS scale can be considered bus powered as a low power device because it

consumes less than 1 unit load of power (<100ma) with up to two non-backlit

displays connected. It does not fully comply with the USB specifications because it

does not support the “suspend state”.

Protocol

This interface supports the standard Universal Serial Bus HID Point of Sale Usage Tables

for scales. Refer to the Universal Serial Bus HID Point of Sale Usages Tables document

for details on this protocol.

Mettler Toledo has additional information to assist software developers to communicate

to the PS scales by USB. Please request document 64068935, USB Protocol

Specifications for PS Scales, from your local Mettler Toledo representative or call 1-

800-786-0812. In addition to the usage tables referenced above, this document

includes the vendor extensions for full PS scale functionality.
