The Atkinson Electronics Trunk Interface RS-232 (AETI-232/TTL2) is a TTL to TTL to RS-232 repeater module. It was designed to interface between STAEFA’s Smart II communication trunk and STAEFA’s Talon Network Manager or Tridium’s Jace Network Manager using the Smart II Driver.
The AETI-232 repeats the communication information it sees on any of the three ports (either TTL or RS-232) to the other two ports (either TTL or RS-232). The AETI-232 has two TTL ports allowing additional quantities of Smart II controllers to operate on a Network Manager RS-232 trunk. The AETI-232 uses an on-board isolation transformer to provide isolation between each of the TTL and RS-232 communication ports.
The AETI is also available in a RS 485 format.
