1. OVERVIEW
DESCRIPTION
The EST-9600 is a serial server that allows multi-drop devices to use Ethernet LANs either
unencrypted or with 128-bit 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
networks. 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 EST-9600s 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 EST-9600 makes it simple and easy to accomplish.
The EST-9600 supports RS-232 serial interface speeds up to 230 Kbps, RS-530 speeds up to 2048
Kbps.
To deliver HDLC traffic via Ethernet in as close to the nature of HDLC as possible, the EST-9600
uses TCP/UDP “best-effort”, 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 of the EST-
9600 include fine-grained 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.

4. INSTALLATION
UNPACKING
The following is included with each unit:
•Unit and external power supply
•Cable for initial setup using a PC
•Manual
•Information regarding warranty, maintenance contracts and repair
SETUP
Initial setup is done through the SETUP port using the serial cable provided. See Section 6 for
specific information.
SECURITY
Link Security
The EST-9600 tunnels HDLC serial protocols encrypted or non-encrypted. The EST-9600
default is encryption enabled. For private networks that are already considered to be
sufficiently secure, turning encryption off may be an acceptable mode of operation.
The EST-9600 has default pass phrases. If encryption is turned on, be aware that the pass
phrases should be changed from the default values.
Management Security
The EST-9600 can be managed via the Serial Setup port, via Telnet, or via a Web Browser. The
serial port can be enabled or disabled using switch 2 on the rear of the unit. Switch 2 must be
up for the serial management port to be active.
The encrypted HDLC data is sent via the ethernet interface. This is the same interface used to
access telnet or browser management. The telnet port can be enabled or disabled. The telnet
port is a non-standard port 8000. This provides some degree of security, as the default port for
telnet is port 23.
Management using the browser port can also be enabled or disabled. In addition, the browser
port can be limited to only 1 or 2 specific IP addresses.
CONNECTIONS
Connect the synchronous port to the equipment using an appropriate cable. See Section 6 for
pinouts and cabling guidance.
Connect the Ethernet port to the local area network using standard ethernet cables. A straight
through patch cord is used for connection to a hub or switch. To other equipment, a crossover cable
may be required.

5. QUICK SETUP GUIDE
For serial or telnet quick setup, the default user NAME is “admin”. The default PASSWORD is
blank, so enter nothing at the prompt. Just press the “Enter” key to continue. If using telnet, the
default IP address is 192.168.0.96, port number 8000 rather than port 23. For serial connections,
use 9600 bps, 8 data bits, no parity, no flow control. For a quick setup, select the following 4
highlighted menu items. The menus are shown in detail below:
2 Set HDLC Tunnel Values
3 Set Ethernet LAN Values
4 Set HDLC Port Values
8 Save and Activate
The EST-9600 can tunnel in encrypted mode or with no encryption. Menu selection 2 is used if you
wish to change from the default of Encryption ON to NONE. For Tunnel Mode, menu selection 3,
set the Tunnel Mode to either Host or Drop. Drop is the default since most units will be drops in
multi-drop applications. When configuring drops, select “5. Primary Host Values”.
At drops it is necessary to enter the IP address of the host by selecting “5. Primary Host Values”.
Drops “find” the host via the IP address. At the Host unit no address is entered for the drops. The
Host discovers the address of the drop from the drop’s connection request to the host. Menu
selection 5 gives you the menu below where the Primary Host Values are entered.

9
The address of the host is entered per the following example:
->: 1 192.168.10.10
In the “LAN Values” menu, enter the IP Address, the Subnet Mask and the Default Gateway for the
unit. This is required in both the Host and the Drop units.
In the “HDLC Port Values” menu, enter the clock choice for the drops and the host. The default is
Internal Clock. There are jumpers inside the EST-9600 that must be set to match the software
setting. See the photos below for details on changing the clock source jumpers.
The internal jumpers are accessed by removing the 2
Phillips head screws that hold on the front panel. Remove
the 2 screws and slide the circuit board forward to expose
the jumpers. There are 2 sets of jumpers. The longer set
of jumpers nearest the front panel set the HDLC serial
interface to RS232 when toward the front panel or
RS422/RS485/RS530 when set away from the front. The
smaller set of jumpers about an inch further back set the
clock source to internal when set toward the front and
external clock when set toward the rear.
Defaults are RS232 electrical interface and internal clock
source.

10
When setting the EST-9600 to Internal Clock source, also set the rate. The Encoding, menu
selection 3, defaults to NRZ (non-return to zero). This is typical for PPP, Frame Relay, X.25 data.
NRZI is often used with IBM SDLC protocols.
After making all the necessary changes, select item 8 from the main menu, “ Save and Activate”.
Remember that after changing the IP address, if the EST-9600 is again accessed for setup via telnet
or a web browser, it is necessary to change the address of the PC to match the IP subnet of the EST-
9600.
