| The
TDW-33 is designed to function reliably within
industrial environments and in areas of high
level interference. The modem has an RS-232
interface supporting terminal data rates up to
115-kbit/s. The TDW-33 is a V.90 modem meaning
that it can support data rates of up to 56 kbit/s
on the PSTN line side. The modem is equipped with
transient protection on the line side and a
“watchdog” that monitors and
automatically resets the modem in the event of a
fault. These functions together with remote
configuration make the modem perfect for
installation at unmanned sites and prevent the
need of costly service trips. The modem also has
password protection, dial-back security and
caller ID answering to ensure that only
authorised users can communicate with the modem
and any connected equipment. The TDW-33 is ideal
for industrial applications as it mounts easily
on to a 35 mm DIN-rail, runs from 12–48-VDC
power supplies, has screw terminal connections
and is tri galvanically isolated. For ease of
setup the modem is supported by the Westermo
TD-tool configuration software. Drivers for
Windows setup are also supplied. |

| The
GDW-11 is a GSM/GPRS modem designed for
industrial applications that can be used on 900
and 1800 MHz GSM networks.The modem requires a
SIM card to provide connection to a network
service provider. The modem contains an enhanced
TCP/IP stack to allow GPRS (General Packet Radio
Service) connections to be made seamlessly and
reliably ensuring maximum availability of the
GPRS connection. If the GPRS connection is broken
the modem can automatically re-establish the
link. Another enhanced feature in the modem
includes the ability to make a CSD connection or
send an SMS message when the DTR signal is
activated, allowing the modem to be used in
applications where the connected device has no
intelligence to initiate a call using AT
commands. If a PIN number is used by the network,
this can be stored in the modem to ensure the
availability of the modem after a power
failure.The modem can also periodically
re-register with the network, this is required as
some networks will deregister a SIM that has not
moved or been active for a period of time. The
GDW-11 is configured with an RS232 /422 / 485
port |

MRD-310 is a robust 3G router designed to provide
remote connectivity across mobile networks. The
unit features an on-board two port switch and a
serial port providing the unit with versatile
connection options. The MRD-310 supports a wide
variety of wireless standards, thus providing
connectivity in as many applications as possible.
Using High Speed Uplink Packet Access (HSUPA) the
uplink capacity is 2 Mbit/s, together with the
7.2 Mbit/s downlink data making the unit suitable
for even high data rate applications. Secure
connectivity everywhere can be achieved using a
VPN which creates secure tunnels over insecure
networks. The unit supports IPSec, SSL, PPTP and
L2TP encryption and certificate management to
secure the tunnel. |
