HackLab.TO Timing Reference A

This is the main timing reference for HackLab.TO (and tick.hacklab.to).

Project Overview

• Built into an American Data 800-series chassis (3U, 10 modules each with line voltage on an edge connector + space for a connector to the back panel)
• Chassis came with 10 AD805 distribution amplifiers (1 BNC in, 1 daisychain out, 6 amplified outputs)
  • Will replace as many as required with other timing-related modules, remaining ones will be used to distribute timing references around

GPS Module

• Will take up 2 slots
• Motorola OnCore UT timing receiver
• 7-segment LED displays for:
  • UTC Time (6 digits, red)
  • Number of SVs in view (2 digits, green)
• LEDs
  • Power (green)
  • Comms (white)
  • GPS Fix (blue)
  • Replace Battery (yellow)
  • Fault (red)
