The EST-9600 is a serial server that allows multidrop
devices to use Ethernet LANs, unencrypted or with 128bit AES encryption. The EST-9600 connects any HDLC
based synchronous protocol serial device through a LAN
and between LANs via routers. The EST-9600 is designed
specifically to support synchronous polling protocols that
are HDLC based. These protocols include SDLC, BDLC,
X.25, Frame Relay, synchronous PPP protocol, etc. These
protocols are often error corrected, and the EST-9600
allows these protocols to work through routed local and
wide area LANs. The EST-9600 uses UDP protocol to
deliver the HDLC traffic, allowing the necessary data
connection over a local LAN and across routed networks.
The EST-9600 functions independently of the device
protocol, allowing HDLC protocols to be carried with no
configuration changes.
An EST-9600 host authenticates with remote drop EST9600s to allow serial synchronous HDLC data connections.
Remote drop EST-9600s can authenticate with both a
primary host and a backup host. This feature makes it
easy to have redundant host sites that will always receive
the same poll responses as the master host site. If the
objective is to have a backup host site or have a second
site that always monitors the RTU responses, the EST9600 makes it simple and easy to accomplish.
The EST-9600 supports RS232 serial interface speeds up
to 230 Kbps, RS530 speeds up to 2.048 Mbps. To deliver
HDLC traffic via ethernet in as close to the nature of
HDLC as possible, the EST-9600 uses TCP/UDP “besteffort”, speedy delivery, rather than the delay and extra
overhead that TCP/IP error-correction and flow control
could cause. Up to 20 drop EST-9600s may be used with
each host EST-9600.
The EST-9600 can be managed through its serial port, via
telnet or with a web browser. Remote configuration is
supported using TCP/IP (telnet) or any web browser.
Security features embedded in the EST-9600 include finegrained configuration and management controls as well as
the ability to turn off remote management functions.
Instead of replacing your existing host computers and
terminals to migrate to ethernet, add the EST-9600 for a
fraction of the cost. OEM manufacturers can design the
EST-9600 into their products or use it as an add-on
method to gain ethernet connectivity.
