1. A networked electronic ordnance system comprising:
a first plurality of pyrotechnic devices connected to a first network bus;
a first bus controller connected to the first network bus, wherein the first bus controller is configured to transmit commands to the first plurality of pyrotechnic devices over the first network bus in order to control activation of the first plurality of pyrotechnic devices;
a second plurality of pyrotechnic devices connected to a second network bus;
a second bus controller connected to the second network bus, wherein the second bus controller is configured to transmit commands to the second plurality of pyrotechnic devices over the second network bus in order to control activation of the second plurality of pyrotechnic devices; and
a bus interface circuit connected to the first bus controller by a first electrical connection and connected to the second bus controller by a second electrical connection, wherein the bus interface circuit is configured to transmit commands to the first bus controller over the first electrical connection, and wherein the bus interface circuit is configured to transmit commands to the second bus controller over the second electrical connection.
