Bausch Datacom – InduBox PSTN III – Reference Manual V1.0c
1. Introduction
This manual is the reference when setting up the InduBox PSTN III modem for your
application. Because of the nature of this product and it's field of application, some
degree of technical background knowledge regarding the application and data-
communication is assumed.
The InduBox PSTN III modem is a versatile communication device designed to provide
a very flexible data communication solution for an industrial environment.
The InduBox PSTN III modem contains a number of options to accommodate different
communication speeds, power supplies and interfaces.
The InduBox PSTN III is designed to transmit and receive –transparent- ASCII
formatted data on a analogue PSTN (Public Switched Telephone Network) line.
Besides serial communication using standard RS-232, other galvanically separated
interfaces are available like RS-232 3-wire and RS-485 3-wire.
Besides a periodical (hard) reset, configurable between 1 and 168 hour, an external
modem reset is possible via the additional 'V+'-connection to ensure a proper modem
working.
The InduBox PSTN III is designed in a robust housing with different power supply
options accepting a wide range of AC voltages.

2. Block Diagram
The block diagram below details the location and interconnection of the different
functional units within the modem. The most important units are briefly described.
AC/DC power supply
The mains supply (ac) must be connected to the InduBox PSTN III modem via a 2 pin
terminal block with screw contacts. Make sure the voltage supplied to the modem is in
the range of the InduBox PSTN III input voltage (see specifications for details on voltage
range).
Long Term Watchdog
A long term watchdog circuit is implemented. The modem will perform a reset each 1 to
168 hour (configurable) and/or if necessary via the external '+V'-connection to prevent a
lock-up. The power supply of the PSTN socket modem module will be disconnected for
a few seconds after the reset period. A ‘heartbeat’-LED (green) is implemented to check
the long term watchdog.
Switched regulator
To create the necessary dc-voltage to power the modem module a 0.5A step down
switching regulator is implemented.

Configuration Interface
The InduBox PSTN III modem has one complete (TxD, RxD, DCD, DTR, RTS, CTS, RI
and GND) RS-232 interface. This RS-232 interface is not isolated and must be used to
configure and/or update the modem module. This interface has a RJ-45 connector.
Isolated DTE interfaces
The InduBox PSTN III has 2 galvanically isolated serial interfaces :
•3- wire RS-232 (RxD, TxD, GND’) & '+V' for external reset
•3- wire RS-485 (A, B, GND’) & '+V' for external reset
Each interface has it’s own RJ-45 connector and can be used in parallel.
V.24 Status LED’s
The V.24 lines to and from the PSTN module have a LED indicator.

4. Ports and Connectors
Before you start the installation, take a moment to become more familiar with the
possible connections to and from the InduBox PSTN III modem.
The InduBox PSTN III has three types of connectors; a Mains terminal block screw
connector, RJ-45 connectors and one RJ-11 connector.
Disconnect the mains power before connecting or
disconnecting the power and/or DTE plugs !
4.1 Mains Power Connection
PIN
1 N
2 L1
Always disconnect the mains power before connecting or disconnecting the power plug.
Make sure the voltage supplied to the modem is in the range of the InduBox PSTN III
input voltage (see specifications for details on voltage range).
When the InduBox PSTN III modem is connected via a standard mains plug, the
used mains socket must be directly accessible and easy reachable.
