Supplemental Data Collection
Will also use Opto 22 data acquisition
Allow synchronized data collection time stamps for 128 I/O points
Ethernet Access Ftp transfer of time
stamped logs Embed simple logic
for preprocessing data

Data Collection
Solo Pro will be use for data collection purposes since it provides a convenient way to log time stamped events (video overlay an file) using equipment INDOT technicians/engineers are familiar with.However, other loop and video detection units will be installed….outputs from those units will be connected to spare (6) Solo Pro Inputs
