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.

7. Watchdog Functionality
To prevent a “total lock-up” of the InduBox PSTN III a long term watchdog is
implemented. This function is created with a separate microcontroller.
The microcontroller itself is guarded with it’s own internal watchdog (+/- 1 second
refresh / green WD LED flash).
This long term watchdog has 2 possible ways to reset the modem :
1. configurable periodically reset
2. external reset triggered by the '+V'-connection (JP4 and/or 5 on 'Meter' position)
7.1 Periodically reset
The power supply will be disconnected during 20 seconds after the selected reset
period IF the modem is NOT connected (inactive DCD signal).
If the reset period is ended and the modem is connected to a remote host (active DCD
signal) the reset will not be conducted. If the reset period is ended + 10 minutes and the
watchdog already past a reset, because of an active DCD signal, the reset will be
conducted! Otherwise, the InduBox PSTN II can be “locked-up” with an active DCD
signal the watchdog will never be able to reset the WAN module.
Time is programmable via the serial setup menu of the modem.
This menu is accessible via the RJ-45 serial interface (9600 bps 8N1) after hitting the
blue 'push'-switch located next to the reset processor onto the modem printed circuit
board.

| Reset period time select [currently 24 hour]
| Do you want to change this [y/n] :
Enter 'y' if you want to change the default 24 hour to another value.
The new value will automatically be stored in non volatile RAM.
7.2 External reset
The power supply will be disconnected during 20 seconds when a negative slope (5-
25V to 0V) is detected on the '+V'-input.
There is no DCD check done in this reset mode.
