Claim 14:
15. A control board of a building environmental management system, comprising:
a microcontroller programmed to control operation of equipment in the building environmental management system;
a first power bus configured to receive and transmit first electrical power with first power parameters;
a second power bus configured to receive and transmit second electrical power with second power parameters, wherein the first power parameters and the second power parameters are different from one another;
a first communication bus configured to transmit data in accordance with a first communication protocol;
a second communication bus configured to transmit data in accordance with a second communication protocol, wherein the first communication protocol and the second communication protocol are different from one another; and
a switchable input/output (I/O) port communicatively coupled to the microcontroller via a switchable communication bus, wherein the switchable I/O port is configured to couple to the equipment,
wherein, based on a target communication protocol of the equipment, the microcontroller is programmed to selectively communicatively couple the switchable communication bus and the first communication bus and to selectively communicatively couple the switchable communication bus and the second communication bus.
