The NK-3RD Third Party Router Interface enables a third-party control system to control an NK Series routing system using the Pro Bel SW-P-08 or the Grass Valley Jupiter ESswtich protocol. Using this protocol, an NK Series router can emulate a Probel router or interface to Grass Valley products via ESswitch (limited to crosspoint switching and crosspoint status / tally requests), allowing control of the NK Series router via a third-party automation system.
