#Project Objective The goal of this project is to collect and organize input from several scales and a human user. The data needs to be in a format that can be easily imported into Excel.

##Assumptions

• There will always be exactly 10 scales
• All data will be present at time of collection (scales loaded, user input completed)
• Values will be displayed as they are collected
• Scale configuration/identity will not change after initial setup (ID comes from scale or USB-to-RS232 Adapter???)

#Physical Components

##Inventory

• (1) Laptop
• (10) Scales
• (10) USB-to-RS232 Adapters
• (10) CAT5 Cables
• (20) CAT5-to-USB Adapters
• (1) USB Hub

##Connection Scheme The following describes the physical connection of each scale to the laptop (note: the USB hub is shared by all scales):

Scale RS232 Port<->USB-to-RS232<->CAT5-to-USB<->CAT5 Cable<->CAT5-to-USB<->USB Hub<->Laptop USB Port
