Firmware update 1.4.0 is now available for the groov EPIC processor, GRV-EPIC-PR1.

Our engineering team released an exciting new update for groov EPIC this week. Here are some of the highlights.

  • OpenVPN technology now on groov EPICFor greater security in data communications, you can now connect the GRV-EPIC-PR1 to a virtual private network (VPN). Configure your EPIC as a client to connect to an OpenVPN server.
  • New options let you configure each network interface independently, for example for setting the order of priority for backup gateways and DNS provisioning.
  • New networking features include diagnostic tools (ping, test tcp port, and more) to test internet connectivity in groov Manage.
  • For Ignition users, you can now choose Ignition or Ignition Edge platforms. The Opto 22 Ignition Edge license (GROOV-LIC-EDGE) works only with Ignition Edge. Contact sales@opto22.com for more details.
