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 originating call, results in real time savings when sev eral 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 manuf acturers' modems are used with different IEDs
requiring unique modem register settings. The DS-100 series also supplies
±12 VDC output terminals, providing con v enient po wer access for external
12 VDC pow ered 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 availab le periodically. The oper ation of the
DS-100 allows for upgrades using an Internal Flash ROM. Review Chapters
2 and 7 for more details.

Chapter 3 - Overview
User Ports
The four or eight DCE User ports will support between 300 - 38,400 bps
asynchronous data transmission rates.
Local Maintenance Port
The Local Maintenance port accepts a terminal or terminal emulator. No
password is required for prog ramming access through this port. Programming access will be a lower priority process than any ongoing data transfer.
Incoming T raffic
Incoming traffic to the DS-100 is answered b y the modem which must be
configured for auto-answer. The DS-100 looks for DCD (carrier detect) from
the modem to know that a call has been received. It then starts monitoring
the data from the modem for a system passw ord (if one is prog r ammed)
followed b y a transfer code. By default, there is no access password.
Remote Programming
Remote programming access can be performed through the Modem input
port. A transf er code sent to this port will access programming mode by
sending “ab0” where “ab” is the default code. Any initial remote access to the
menu via the Modem port will require (in default configuration) a programming password, with “teltone” being the default password. Once access is
gained, an inactivity timer will terminate programming connection after a
programmable (def ault=3) number of min utes of no activity.
Routing Commands
The DS-100 monitors the data flow into the Modem port for data switch
commands. To enter a command, there m ust be a pause in the data stream
into the Modem port, followed by a 3-character command string, follow ed b y
another pause in data. All commands are 3 characters in length, and all 3
characters must be entered within a 2 second period. The minimum length
for the pauses before and after the command string are user programmable
from 0.1 to 2.0 seconds, in 0.1 second increments.
If the string is not a valid command, pauses too short, or the 3 characters are
not entered within a 2 second period, the string will be forwarded to the
currently selected User port. If the string is a valid command, it is not
forwarded to the User port.
The DS-100 recognizes the following commands:
ab0 Connects to maintenance menus for remote configuration
ab1 thru ab8 Connects the Modem port to the selected User port
ab? Reports which User port is currently connected to the
Modem port
The “ab” prefix f or the commands is user prog rammable.
6 40-400-00022 Rev. B
Emergency Interrupt Input
When an AC or DC voltage is applied to this input, located on the rear panel,
the unit will terminate an on-going transfer by dropping DTR to the modem
port. The unit sends a configur ation string to the modem to prepare it for the
next call. The configur ation string is user programmable. The Interrupt
feature is disabled in the f actory default setting. It allows the user a means to
remotely abort a lengthy data transfer when another operation is desired.
Users can apply DC voltage through auxiliary relay on “B” version of
Teltone’s Substation Line Sharing Switch, (SLSS - must be on another
central office line), through a SCADA system or other intelligent de vice.
No Priority
In this mode, no port will be able to interrupt a data transfer on another port.
No Priority is the default factory setting.
Total Priority
In this mode, User P ort 1 is the highest priority port. If another User port is
active, its activity will be terminated to allow User port 1’s request to be
serviced. User port 2 has the second highest port priority. User port 8 has
the lowest priority. When a higher priority port interrupts a data transfer, the
unit will not initiate any action to reestablish the original transfer.
Data Routing
Incoming traffic is initiated when the DS-100 sees carrier detect go active on
the Modem input port. When incoming tr affic arriv es at the modem port,
(modem must be configured for auto-answ er) the unit may expect to receive
an access password fo llowed by a routing command (transf er code). If the
command is successful, the modem port will be logically connected to the
specified User port. The modem can be progr ammed from the Local Maintenance port.
Transfer Data Connection to Another User Port
When there is a pause in data flow into the Modem port, the unit will monitor
the next set of characters to see if they are a v alid data switch command. If
the string is valid and of correct length, the Modem port will be logically
connected to the newly selected User port. If the string is not valid, the unit
will forward the string to the currently selected User port. The required
pause duration is programmable in 0.1 second increments . Factory default is
>1.0 second.
Outgoing Traffic, Data Switch Idle
The unit expects either DTR or RTS to go active as a request for service.
The unit is programmable to select which of these signal(s) will be considered a request for service. The unit will respond by logically connecting the
requesting device to the Modem port.
40-400-00022 Rev. B 7
Outgoing Traffic, Data Switch Active
If there is a request for service and the unit is set to No Priority default, and
the unit is active on another User port, the unit will not respond to the request
until it is idle. If the unit is set for Total Priority, and a higher priority port
requests service, the unit will abort the current transfer, drop DTR to the
Modem port, and wait until the Modem port is ready for a new tr ansf er.
When the unit is ready to support the next call, it will logically connect to the
Modem port.
Disconnect Procedure
Incoming calls are disconnected when DCD goes inactive on the Modem
input port. Outgoing calls are disconnected when DTR or RTS (whiche ver
was used to originate the call) goes inactive. When either the Modem input
port or active User port has their control lines go inactive, the unit will go idle.
Data T ransfer Inactivity Time-out
The Data Transfer Inactivity time-out can be set betw een 1 and 10 min utes in
1 minute intervals. The default time-out is 3 minutes. The user can also
program the unit for no activity time-out.
Loss of Power
The unit will be totally inoperative when pow ered do wn. The only output will
be an alarm contact closure.
Version 2.00 Upgrade
The Version 2.00 upgrade adds the following features:
• expanded modem initialization string from 25 to 50 characters
• up to 64 port expansion using a single transfer code (cascading)
• site Sign On message operation
• case sensitive transf er code operation
• default port operaton
• port rollover operation
• reconnect to last accessed port operation
• port time-out alarm enable/disable
AC Power
Teltone part numbers 250-00204-05 (DS-104) and 250-00204-06 (DS-108)
and later are properly labeled for 90 - 120 VAC power use. Earlier models
are also able to operate with AC power, but are not correctly labeled. Ref er to
Figure 7 for AC connections .

Chapter 4 - Typical Applications
Electric utilities are continually searching for wa ys to lo wer oper ating costs,
improve efficiencies, and pro vide better customer service. Various distribution automation techniques are quickly being introduced and embraced. This
is causing a proliferation of IEDs, such as electronic meters, relays and
digital fault recorders to be installed into electrical substations. Due to
different IED manufacturers using diff erent protocols, communicating with
these devices can be difficult. In addition, if an analog telephone line is used
as the primary communication link, each IED requires its own modem to
convert from an analog signal to a digital one.
Figure 1 Single Stand Alone Configuration
To avoid the expense of using multiple modems , a user can install the DS100 in front of the IEDs:
40-400-00022 Rev. B 9
Figure 2 Cascade Configuration
The user can have up to 64 connections by connecting up to 8 DS-100 units
behind a primary DS-100:
10 40-400-00022 Rev. B
Figure 3 System Configuration with SLSS and DS-100
The DS-100 has been designed to work in conjunction with the Teltone family
of Line Sharing Switches and Cellular Interface Units. Depending on the
application, a combination of these devices can provide an efficient, cost
effectiv e system solution.
If telephone service is needed or desired, users can install the Teltone Substation Line Sharing Switch (SLSS) and modem in front of the DS-100. This
configuration enables users to communicate with multiple IEDs through the
DS-100, saving on multiple modem expense while pro viding cost sa ving
phone service:
40-400-00022 Rev. B 11
Figure 4 System Configuration with CIUS and DS-100
If cellular service is needed or desired, users can install Teltone’s Cellular
Interface Unit for Substations (CIUS) and cellular modem in conjunction with
the DS-100. This allows users to take advantage of low cost, reliable, easily
installed cellular communications as a medium between their host/ polling
location and their IEDs:
Figure 5 System Configuration with CIUS, SLSS and DS-100
If users have a need or desire to use a single cellular circuit for voice and
data to communicate with multiple IEDs, the user can combine Teltone’s
CIUS, SLSS and DS-100. This provides a cost competitive, easily installed
and reliable distribution automation system solution:

Chapter 5 - Installation
1. If rac k mounting, attach the mounting ears to both sides of the DS-100
using the enclosed screws. Unit will fit in either a 19" or 23" rack and can be
flush or center mounted.
2. Position unit into rack, aligning mounting ear holes with rack holes.
Secure unit into place by affixing screws with corresponding washers.
3. To power the modem (not ncluded) from the DS-100, insert the bayonet
end of the modem power cable into the modem. Assuming your modem
operates off 12 VDC , insert the ribbed or marked lead into the “+12V” terminal. (You may w ant to test the polarity of the modem power leads before
connecting.) Insert the other lead into the ground terminal marked, “GND”.
Fiber optic isolators normally used the +12 VDC and -12 VDC connections.
*NOTE* The -12 VDC connection is NOT recommended for powering modem
installations.
4. Connect the modem to the DS-100 b y attaching a DB-25 male to DB-9
female RS- 232 cable, not included, to the DB-9 male Modem port on the
back of the unit.
5. Attach an RJ-11 modular cab le between the modem and the PSTN or
communications device. (i.e. SLSS, CIUS or phone line.)
6. Connect a DB-9 male RS-232 cab le , not included, into one of the User
ports. (Figure 6 depicts connections to User ports 1 and 2.) Connect the
other end of the cable’ s DB-9 f emale connector to y our IED. Connect the
remaining User ports to other IEDs in a similar fashion.
7. Remov e the yellow terminal block cover and apply po w er to the DS-100
by connecting the power cab le from your substation power source (42-150
VDC or 90-120 VAC at 60 Hz) to the unit’s po wer terminals marked “+” and
“-”. When connecting to DC power, make sure you connect the “+” po wer
cable lead to the “+” terminal and the “-” power cable lead to the “-” terminal.
Next, connect the chassis ground marked “GND” as specified by local
practices. Replace terminal block cov er when finished.
8. If the user w ants to utiliz e the Emergency Interrupt feature, connect wire
leads into the Emergency Interrupt terminals. Connect the other wire end to a
switched AC or DC po wer source . (The Teltone SLSS auxiliary relay may be
used for this application.)
9. If the user w ants to utiliz e the Remote Alarm feature, connect wire leads
to terminal connections marked “ALRMS”. The alarm contacts close during
an alarm.
10. Connect a terminal or PC, loaded with a communications softw are
program to the Local Maintenance port located on the front of the unit using
a DB-25F to DB-9M adapter (if required) and a DB-9F to DB-9M RS-232
