1. Introduction
This manual is the reference book when setting up theDinBox PSTN(485) 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 DinBox PSTN(485) modem is a versatile communications device designed to
provide a very flexible data communication solution for an industrial environment.
To ensure problem free communication, theDinBox PSTN(485) is equipped with a ‘long
term’-watchdog. This circuit will ‘hard’ reset the modem every 24 hour.
The DinBox PSTN(485) is designed to transmit and receive data on the Public
Switched Telephone Network -PSTN.
The DinBox PSTN(485) has a lot of enhanced communication features implemented :
-error correction / data compression
-Caller ID detect
-V.22bis fast connect
-2-wire analogue leased line
-dump mode
-asynchronous DTR dialing
The DinBox PSTN(485) is designed in a robust 22.5 mm wide DIN rail housing with a
wide range DC-power supply.
The DinBox PSTN(485) version has an internal RS-485 2-wire and 4-wire interface.
See chapter 7 for more details about this interface.

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.
Power Supply
The power supply (DC) must be connected to theDinBox PSTN(485) modem via a
terminal block with screw contacts. Make sure the voltage supplied to the modem is in
the range of theDinBox PSTN(485) input voltage (see specifications for details on
voltage range).
This input is protected against reversed polarity with a serial diode.
DTE Interface
The DinBox PSTN(485) modem has a RS-232 interface (RJ-45) witch can be
connected to a computer or similar device via included RJ-45/DB-9 serial cable.
The DinBox PSTN(485) has a buid-in 2-wire and 4-wire RS-485 interface.
PSTN Modem
The DinBox PSTN(485) modem has a Conexant modem chip. Connection with the
PSTN network is done via a standard RJ-11 connector.
Watchdog circuit
A long-term watchdog circuit is implemented. The power supply of the PSTN modem will
be disconnected for a few seconds after the selected reset period.
If a part of theDinBox PSTN(485) is ‘locked’ after e.g. an unexpected high ESD
discharge, surge pulse or an internal lock-up, this watchdog will always insure the
continuity of communication.

The DinBox PSTN(485) modem will detect the DTE port speed (auto baud), number of
data bits and parity type from the "AT" header that precedes every command (in async
mode).
The &W command automatically saves the baud rate, number of data bits, parity and
number of stop bits.
4.3 PSTN connection
The DinBox PSTN(485) modem has to be connected to a PSTN line via the RJ-11
connector.
There are 4 pins connected :
A / B ?connection to the telephone network
A’ / B’ ?connection for a parallel connected telephone
A is always connected to A’ and B is always connected to B’. Therefore it is sometimes
necessary to use a 2-wire telephone cable (only 2 wires in the middle) when theDinBox
PSTN(485) is connected to a digital PABX with analogue telephone lines. A’ and/or B’
can be used as signalling lines between the telephone and the PABX.
5. LED indicators
TxD Transmit Data from DTE to modem
RxD Receive Data from modem to DTE
DCD Data Carrier Detect from modem to DCE
WD Watchdog heartbeat 1 sec on/off
6. Watchdog functionality
To prevent a “total lock-up” of theDinBox PSTN(485) a long term watchdog is
implemented. This function is created with a separate RISC micro controller. The micro
controller itself is guarded with it’s own internal watchdog (+/-1 second refresh/ WD
LED flash).
The power supply to the communication control processor and the modem module will
be disconnected for a few seconds after +/-24 hour IF the modem is NOT connected
(inactive DCD signal).
If the reset period is endedand the modem is connected to a remote host (active DCD
signal) the reset will not be conducted.
If the reset period is endedand the watchdog already past a reset, because of an active
DCD signal, the reset will be conducted after +/-10 minutes !
Otherwise, if theDinBox PSTN(485) is “locked-up” with an active DCD signal the
watchdog will never be able to reset the WAN module.

7. RS-485 interface
The DinBox PSTN(485) has an internal RS-485 4-wire and 2-wire interface. See the
next chapters for more information about the use and setup of this interface.
7.1 External connections
The RS-485 interface must be connected via the screw contacts on the opposite side of
the power connection.
2-wire 2-wire signal flow

2Bin/out XMIT/b input –from DTE
3Ain/out XMIT/a input –from DTE

(1) The DTR signal is not active when the DTE–DCE connection is done by using a 3-
wire RS-232 interface (RXD, TXD and GND). Use JP1 position 2-3 to lock the RS-232
interface. By default JP1 position 1-2 is used : when the DTR is active, f.e. during
configuration of theDinBox PSTN(485), the RS-232 interface is active. If no DTR, the
RS-485 interface is active.
(2) It is preferred to disable autosensing and lock the interface speed with the +IPR
command when the baudrate is higher or equal then 9600 bps.

7.4 Example configuration for RS-485 communication
The RS-485 interface must be connected via the screw contacts on the opposite side of
the power connection.
Connect a terminal (PC) to the RS-232 interface (RJ45). TheDinBox PSTN(485) will
automatically switch to the RS-232 interface if DTR is present (JP1 on 1-2 position).
Verify the correct communication parameters, for example 9600 8N1.
Send the commands below to theDinBox PSTN(485) modem.
at&f ‘ factory reset
at+ipr=9600 ‘ autosensing off, lock on 9600 bps
at&d0 ‘ no DTR
at&k0 ‘ no RTS / no flow control
atk0 ‘ dump mode
ats0=0 or x ‘ no answer (0) or answer after x rings
ate0 ‘ local echo off
at&w ‘ save in NVRAM
It’s important to disable local echo (ate0) when RS-485 2-wire is used !
