2. Product overview
2.1. Product function
The RAS provides to authorized users a remote access to the
machines connected either to an IP LAN or to a serial RS232-RS485
interface, as if his PC was directly connected to the LAN or to the
RS232.
On the user PC side, the communication can be set either with a dial
up modem or through an internet access.
Direct dial-up communication Internet communication

Overview
Remote access server User manual ref 9014509-03 Page 11
2.2. Remote PC to RAS communication capabilities
The communication between the remote user and the RAS can be either a
dial-up communication or be established through the internet.
If the communication is established through the Internet, the public IP
address assigned to the RAS can be dynamic or fixed (IP call back and
DynDns functionalities).
The compatibility between the PC modem and line on one hand, and the
RAS on the other hand, is summarized in the table below :

2.3. Functions overview
Authorized users
The RAS prevents unauthorized access; it manages an authorized users
list; a user name and a password is assigned to each of them.
Safety callback
If that option has been assigned to a user, the RAS calls the user back to
its stored telephone number.
On demand callback
For economical reasons, and if that option has been authorized to a user,
the RAS can callback the user to the telephone number he demands.
Fire-wall
The built-in firewall allows to limit the IP addresses and TCP ports to which
each authorized user can connect.
Internet DynDns and IP callback
The RAS provides DynDns and IP callback functions; that functions allow
to connect the user remote PC to the RAS through the internet even if the
RAS public IP address is dynamic.
Secure connection over Internet (VPN)
The RAS is able to establish a secure connection (VPN) over the internet :
The VPN can be either PPTP for usual use, but also IPSEC or TLS.
With the VPN, a remote authorized user can connect to any machine of
the LAN.
DNAT
If a VPN cannot be established through the internet, the DNAT function
allows the user to access to some machines of the network.
RS to IP gateways
The product includes an up-to-date RS to IP gateway, allowing the user to
connect remotely as well to IP as to asynchronous devices.
Emails – sms
A stored emails or sms can be transmitted each time the digital input is
closed or opened.

Overview
Remote access server User manual ref 9014509-03 Page 13
The RAS can also transmit any email or SMS coming from an SMTP client
connected to the IP network.
Html configuration
The RAS is configured with a PC and a web navigator. The configuration
can be achieved through the ethernet interface or remotely.
For safety reasons, the remote configuration can be forbidden.

2 Supply voltage
RAS-M156e or RAS-I1128e
The supply voltage must be strictly lower than 60 VDC and higher than 9
VDC. The consumption is 125 mAat 24 VDC.
RAS-G134e or RAS-G12e
The power supply module must be powerful enough to provide the peak
current which occur during a GSM communication.
The supply voltage must be strictly lower than 30 VDC and higher than 9
VDC. The consumption is 170 mAat 24 VDC when the product is on-line.

Installation
Page 18 User’s guide ref 9014509-03 Remote access server
4 Ethernet interface
The ethernet interface is a 10 Mb/s interface.
To connect a PC directly to the RAS, use the cross wired red cable
provided with the product.
5 Fans
To avoid overheating when the ambient temperature is high, leave a 1 cm
space on each side of the product.
6 Telephone line connection (RAS-M156e)
The RAS-M156e is designed to be connected to an analog telephone
line.
That line can be an analog public line (PSTN subscriber line) or an analog line connected
to a company telephone switch PBX (also called extension line).
If the RAS line is an extension line, connected to a company PBX, it must be a Direct
Inward Dialing line (DDI or DID) in such a way that the remote user can dial the RAS
number and be connected directly to the RAS bypassing the operator.
Important nota : The type of public lines connecting the company PBX to the public
network does not matter; it can be PSTN but also ISDN, for instance.

Installation
Remote access server User’s guide ref 9014509-03 Page 19
7 ISDN connection (RAS-I1128e)
The RAS-I1128e is designed to be connected to a ISDN BRI interface
(EURO-ISDN compliant).
8 GSM products installation ( RAS-G134e or RAS-G12e)
Checking the GSM reception signal level before installing
Before installing the product, check that the GSM reception signal level is
good enough at the location you want to install the product; that test can
be done with a usual mobile phone using the same provider.
The signal level must be good or excellent.
GSM subscription
The micro-sim card must be inserted in the slot located at the top of the
product.
No password must be set.
Antenna
If the cabinet in which the RAS has to be installed is made of metal, the
antenna has to be installed outside the cabinet; for instance on the top of
the cabinet.
The antenna must be ordered separately; the models below are available :

ANT200
0 db gain - magnetic ANT200 0 db gain ANT200 3 db gain
Checking the reception signal level after installation
When powering the product on, the L / led gives an indication of the
GSM signal quality :
the L / led Signification
… briefly blinks 3 times The quality of the reception signal is fine
… briefly blinks 2 times The quality of the reception signal is
acceptable
… briefly blinks 1 time The quality of the reception signal is
poor
… is turned off No reception
Is a GSM voice communication possible ?
has the sim card been correctly inserted ?
The Led must blink 3 times to ensure the transmission quality will be good.
9 GPRS service availability ( RAS-G12e)
GPRS and GPRS-EDGE are services using the usual GSM network.
The GPRS service provides an IP permanent connection to the Internet at
a medium data rate.
