The SLM SiteLync network modem is an integrated package consisting of a
LonTalk adapter and Telco interface, allowing communications with distant
LonWorks networks using telecommunications media. Its non-router based
design provides maximum connectivity value at minimum levels of installation
and operation cost. It can replace older solutions using multiple units that have
non-standard mounting and power requirements.
LonTalk Adapter
The integral LonTalk Adapter provides Network Services Interface (NSI mode)
or Network Interface functionality (MIP mode). It allows any host to implement
the upper layers of the LonWorks protocol, so applications on the host can send
and receive network variable updates and explicit messages, as well as poll
network variables. The SLM SiteLync network modem must be ordered for use
in either NSI mode or MIP mode. It is not easily field changeable since a factory
configuration of the hardware determines the operating mode. It is available with
either FTT-10A, TPT/XF-78, or TPT/XF-1250 LonWorks network transceiver.
Telco Interface
When ordered with one of the integral telephone service interfaces, the SLM
SiteLync network modem provides the means to connect distant LonWorks
networks using analog (PSTN), digital (ISDN), or cellular channels.
The internal analog modem options in the SLM SiteLync network modem use
proven V.34 terbo modulation, transferring data at 33,600 bits per second. Dial-
up as well as 2-wire leased lines (for North America only) are supported. The
internal ISDN modem (for Europe only) can connect at 64 Kbps using the S/T
interface. The internal cellular modem uses the AMPS protocol (for North
America only) at data rates up to 4800 bps.
Power Supply
Internal power supply options are available for 10-35VAC/DC or 100-240VAC.
This supplies all necessary power for the SLM unit.
