General Information
The DSX-LAN(M) module is typically used to connect a
Master Controller to the Host or Comm Server PC over a
Local or Wide Area Network. The WinDSX software is
inherently TCP/IP capable and can redirect communication,
that would normally be transmitted out a serial port, over a
LAN/WAN to a particular IP address. The DSX-LAN(M)
module receives that communication and converts it to RS-
232 or RS-485 that connects directly to the Master Contoller.
This adds another avenue of flexibility to WinDSX by utilizing
TCP/IP communications as well as dial-up modem and direct
serial port connectivity. All three means of communication can
be used at the same time in the same system. The DSXLAN(
M) is powered from the DSX Controller which can
provide battery backup.
The DSX-LAN(M) module is sold in two different configurations.
The DSX-LAN which is the module with IP communications
as the only method of connectivity. The DSXLAN(
M) has dial up modem backup. The DSX-LAN module
must be ordered with the (M) option along with the DSX
modem to support the dial-up backup feature.
Other Applications
The DSX-LAN(M) can also be used at Slave Controllers
with the use of the PC Master Software. PC Master is a DSX
software application that emulates a Master Controller. It gets
its download from the Comm Server PC and communicates
with all of the Slaves just like a Master Controller does. What
is different about the PC Master software is its ability to communicate
with each Slave Controller via TCP/IP or with a
serial port connection. This allows Slave Controllers to be
placed on the LAN and each one or each group of controllers
to have a LAN connections using a LAN(M) module. Modem
backup is not available for slave controller communication.
Dial-up Modem Backup
The DSX-LAN(M) module has a 9 pin serial port that is used
to connect a DSX modem for communications redundancy.
When the LAN(M) module determines a loss of network
connectivity it switches to “Modem Mode” which allows the
controller to call the Comm Server or Host PC via the modem
when necessary. When the Network connection is re-established
the Controller reconnects over the LAN. The modem
and the LAN(M) module are powered from the Controller
and are connected to each other via the supplied serial cable.

Power
The DSX-LAN(M) is powered from one of the Controllers
12VDC outputs requiring a mere 300ma. Powering the
module from the DSX Controller provides a good stable
battery backed up source.
Monitoring
The DSX-LAN(M) is designed to fit in the same Equipment
Cabinet as the DSX-1048 and DSX-1022 Controllers. It can
mount on the inside or rest in the bottom of the enclosure. It
has three mounting holes and removable terminal blocks. |
