[. . . ] [. . . ] 12 of the connections are designed as Logic connections only and will accept contact closure or 5V TTL for input or provide a maximum of 40V/500mA for output. The remaining 4 connections can also be used for Logic connections or as variable voltage control inputs (e. g. The EX-LOGIC also provides a serial port for the output of command strings that can be used to send action commands to other equipment in the system. The EX-LOGIC communicates with the Tesira SERVER or SERVER-IO over Ethernet and is powered by PoE.
