integrated Ethernet Switch (iES-6), is a rugged 6 port layer 2 managed gigabit Ethernet switch with end node timing and discrete signal capabilities for demanding test instrumentation environments on airborne, shipboard or mobile ground vehicles.

Programmable or data driven discrete outputs can be used to control end node devices on or off the network as well as feedback into the iES-6 from discrete inputs.

With multiple time sources and outputs the iES-6 provides end node device time signals. iES-6 contains a high time accuracy internal GPS receiver and a hardware based IEEE-1588v2 time engine both able to drive the internal IRIG-A/B/G Time Code Generator (TCG) for time outputs.

The integrated board stack architecture and front panel allow for user specifi c functions and connector interfaces to be implemented without compromising system architecture or integrity

  • (6) Tri-Speed Ports with Layer 2 Switch Management & Diagnostics
  • Internal GPS Receiver & IRIG-A/B/G Time Code Generator
  • IEEE-1588v2 Clocks: Master, Slave, Ordinary/Boundary or Transparent (P2P & E2E)
  • (8) Programmable Discrete Outputs & Reset Discrete Input
  • (3) IRIG DC/1PPS Outputs & (2) IRIG AM Outputs
  • Full Non-Blocking Wire Speed Performance for All Frame Sizes Up to 9.6KB
  • CLI, Web GUI or SNMP Command, Control & Monitoring
