SLTA-10 Serial LonTalk Adapter Models 73351, 73352, 73353, 73354, 73351R, 73352R, 73353R, and 73354R Features Serial EIA-232 interface connects host processors and modems to LonWorks networks 1200 to 115,200bps serial bit rate with autobaud detection Automatic dial-out with compatible modem DIP switch selectable NSI and parallel MIP (SLTA/2 compatible) operating modes Integral FTT-10A, TPT/XF-78, or TPT/XF-1250 transceiver Color-coded, removable screw terminals for network and power wiring Conguration DIP switches accessible without opening chassis 9-30V AC or DC power input via removable screw terminals or barrel con- nector Metal enclosure for desk or wall mounting CE Mark, UL, cUL, TV Description The SLTA-10 Serial LonTalk Adapter is a high-performance LonWorks interface for use with laptop, desktop, or embedded computers equipped with an EIA-232 serial interface and a compatible operating system. Designed for use in LonWorks control networks that re- quire remote dial-in/dial-out network access or a host processor to monitor, manage, or diagnose the network, the SLTA-10 adapter is ideal for industrial control, building au- tomation, and process control applications. Models 73351R, 73352R, 73353R, and 73354R are compliant with the European Directive 2002/95/EC on the restriction of the use of certain hazardous substances (RoHS) in elec- trical and electronic equipment. The SLTA-10 adapter provides both network services interface (NSI) functionality for use with LNS-compliant tools, such as the LonMaker for Windows Integration Tool, and net- work interface functionality for use with legacy LonManager API-based tools. The SLTA-10 adapter is supplied in a metal enclosure with rubber feet for desk mounting, and key-hole slots for wall mounting. Conguration DIP switches are accessible without disassembly of the chassis, simplifying conguration of the adapter. The SLTA-10 adapter operates at 10MHz and includes an integral twisted pair transceiver. The network wiring is polarity-insensitive, and is connected to a removable screw terminal block. www.echelon.com The interface with the SLTA-10 adapter is The LonWorks Network Services (LNS) ar- A DB-9 connector is provided for connec- managed by the SLTALink Manager soft- chitecture allows over 16,000 installation, tion to the host.
