Introduction
This manual is the reference book when setting up the DinBox 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 datacommunication 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, the DinBox 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.

Power Supply
Watch DOG Power Supply The power supply (DC) must be connected to the DinBox PSTN(485) modem via a terminal block with screw contacts. Make sure the voltage supplied to the modem is in the range of the DinBox 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 the DinBox 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.

DinBox PSTN Reference manual – V1.3
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’ A B B’
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 the DinBox 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.

Watchdog functionality
To prevent a “total lock-up” of the DinBox 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 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 and the watchdog already past a reset, because of an active DCD signal, the reset will be conducted after +/- 10 minutes ! Otherwise, if the DinBox PSTN(485) is “locked-up” with an active DCD signal the watchdog will never be able to reset the WAN module. Bausch Datacom NV

(1) The DTR signal is not active when the DTE – DCE connection is done by using a 3wire 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 the DinBox 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.

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). The DinBox 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 the DinBox PSTN(485) modem. at&f at+ipr=9600 at&d0 at&k0 atk0 ats0=0 or x ate0 at&w
‘ factory reset ‘ autosensing off, lock on 9600 bps ‘ no DTR ‘ no RTS / no flow control ‘ dump mode ‘ no answer (0) or answer after x rings ‘ local echo off ‘ save in NVRAM
It’s important to disable local echo (ate0) when RS-485 2-wire is used !

Enhanced features
8.2.1 Dump mode When the DinBox PSTN(485) receives a character from the DTE, during the call setup and/or speed negotiation, the modem will stop all further negotiations and will go off-line. We have added ‘dump mode’ to prevent this. atk1 atk0
stop negotiation when a character is received dump mode active
8.2.2 Leased Line configuration It’s possible to configure the DinBox PSTN(485) modem as a 2-wire leased line modem. This point-to-point setup has always an originate and an answer side. What do you have to know before you start configuring the modems : Specification of the DTE port : If asynchronous
what is the used speed ? data / parity / stop bits ? flow control ? is DTR supported ?
If synchronous
is DTR supported ?
eg. 9.600 bps eg. 8 N 1 eg. RTS/CTS
To configure the modems you can use a standard terminal software package. If the DTE uses asynchronous communication it is very important to use the same baudrate as the DTE port when the modem is configured. This asynchronous baudrate will be saved when the modem receives the AT&W command. ANSWER

It is possible to change the transmit level with register S91. Default transmit level is –10 dBm. How to reset the modem after a leased line configuration : ?? Connect an asynchronous terminal to the DTE port of the modem. ?? You have to run a standard terminal software package on the same baudrate as you have used for configuring the same modem for leased line. ?? At this time it is possible to give a full reset command (at&f&w) just after (within 3 seconds) you switch on the modem.
8.2.3 Asynchronous DTR-dialing The modem will automatically dial the saved number if DTR is changing from an inactive to an active state when asynchronous DTR-dialing is active.
commands Information at&f factory reset at&q7 enable asynchronous DTR-dialling at&z0=x save telephone number in slot 0 x = telephone number at&v

8.2.4 Selective CID answer The modem will ONLY automatically answer a call from one predefined telephone number.
commands Information at&f factory reset at+vcid=1 enable CID at&z0=x save telephone number in slot 0 x = telephone number at&v
to verify the saved number
atc1 ats0=0
