VMA16s (32-bit) and VMA18s are programmable digital controllers

tailored for VAV applications that can be switched between MS/TP and

N2 Communications protocols. When they are used as MS/TP devices,

they communicate through the BACnet® Master-Slave/Token-Passing

(MS/TP) protocol. In N2 mode, they can be used as replacements for

legacy Johnson Controls® controllers.
