control networks that require a PC to monitor, manage, or
diagnose the network, the PCLTA-20 adapter is ideal for industrial
control, building automation, and process control applications. The
PCLTA-20 adapter features support for a wide range of transceivers,
downloadable memory, a network management interface, and Plug n’
Play capability with Microsoft
®
Windows 95, 98 and NT operating
systems.
The four versions of the PCLTA-20 with integral twisted pair
transceivers support the TP/FT-10 (model 74401), TP/XF-78 (model
74402), TP/XF-1250 (model 74403), and TP-RS485 (model 74404)
channels, respectively. The model 74405 PCLTA-20 supports SMX
transceivers, and may therefore be used on a wide range of channels,
including Echelon’s PL-10, PL-20, and PL-30 power line channels.
The PCLTA-20 adapter provides both network services interface (NSI)
functionality for use with LNS-compliant tools, and network interface
functionality for use with older LonManager API-based tools.
Echelon's PCLTA-20 is for use only with IBM AT or compatible UL
listed personal computers that have Installation Instructions detailing
user installation of card cage accessories.
