Chapter 1 - General Description
The Teltone DS-100 Series Data Switch allows users to communicate with
up to 64 Intelligent Electronic Devices (IEDs) through a single, RS-232 serial
connection. The DS-100 is available in 4 and 8 port versions and has been
designed to be operated independently or as part of a distribution automation
system. The unit has been engineered to withstand the rigors of substation
and other hazardous environments, meeting IEEE C37.901-1989SWC surge
withstand capability and FCC Part 15 Class A requirements for use in
industrial/business applications.
The DS-100's ability to communicate with multiple IEDs from a single origi-
nating call, results in real time savings when several IEDs must be polled at
the same time. The unit has been designed to work in conjunction with the
family of Teltone Line Sharing Switches and Cellular Interface Units. This
allows users to use each device in a stand alone mode, or together in a
system configuration.
Depending on the application, some users will find it more cost effective to
install the DS-100 with one modem situated in front of the unit instead of
putting a modem in front of each IED. This also simplifies potential protocol
conflicts where different manufacturers' modems are used with different IEDs
requiring unique modem register settings. The DS-100 series also supplies
±12 VDC output terminals, providing convenient power access for external
12 VDC powered modems and ±12 VDC for fiber isolators.
The DS-100 has a wide power input operating range between 42 to 150 VDC
or 90 to 120 VAC.
Product upgrades will become available periodically. The operation of the
DS-100 allows for upgrades using an Internal Flash ROM. Review Chapters
2 and 7 for more details.
