Connecting with Internet Explorer
You will need to initially configure the EtherLink/2 for your specific IP address and
serial port parameters. If you know the IP address then you can change the
parameters by connecting to the EtherLink/2 using Internet Explorer.
Once you have established an IP address for the EtherLink/2 you may do all of your
configuration by connecting with Internet Explorer.
The EtherLink/2 is shipped with Default IP Address: 192.168.1.201 . If it does not
answer to that address, then you must communicate with the device as described
below in Verify/Change Setup.(RS-232)
You will be asked to login. The default user/passwords are ASI/ASI and asi/asi. You
may change these once you have connected.

EtherLink/2 System Configuration
The configuration consists of the Network Setup, the Monitor.Net, and the Serial
Port parameters. Typical parameters are shown.

DHCP
Do not let the DHCP server assign IP addresses except temporarily during initial
network configuration. The remote client software must connect to the EtherLink/2
to a specific IP address.
IP Address and Port
You need to assign IP Address, Subnet Mask, Gateway and Port consistent with your
Local Area Network. The default IP Port is 3001.
IP User Limit
The EtherLink2 supports 1 TCP/IP Connection and up to 3 simultaneous UPD
connections based on the IP User Limit setting. You may limit the number of
simultaneous UDP connections by setting the IP User Limit.
The TCP/IP connection is required by the ASI OPC server. The first UDP
connection is usually used by ASI Expert for system testing and maintenance. If
there are any UDP connections, the TCP/IP connection gets every other turn to send
messages on the serial communication bus..
The UDP connections take turns with the remaining bandwidth. This can slow down
communications and generate occasional COM errors for the UDP connections.
Monitor IP Address and Port
The EtherLink/2 can forward Notify Messages from the ASI serial bus, to the
Monitor Software. You must specify the IP Address and Port of the ASI Monitor
software.
WebLink IP Address and Port
If Remote Point Trends is checked, the EtherLink/2 can forward Remote Points
received on the serial port to WebLink at a specific IP Address and Port.
Serial Port
You must specify the Baud Rate, Stop bits [Default 2] and Timeout [Default 1000
ms] for the ASI serial bus.
Notify Address
Any Notify sent to the Notify Address will be forwarded to the Monitor IP Address
and Port. If the Notify Address is not a Global Address, then the EtherLink/2 will the
EtherLink/2 does send an acknowledge, ACK, response to the ASI device on the
serial port. It turns out that global notify messages sent to the global address 23264
DOC-1643 (2008-09-16) EtherLink/2 User Manual Configuring EtherLink/2 •1-7

(0x5AE0) are better at cutting through a busy serial bus than non-global
acknowledged messages.

User Account Setup
The default user/passwords are ASI/ASI and asi/asi. You may change these once you
have connected. Be sure to remember your new password!
You must save any changes before changing to another screen.
DOC-1643 (2008-09-16) EtherLink/2 User Manual Configuring EtherLink/2 •1-9

Network Time Configuration
A new feature of the EtherLink/2 is the use of Simple Network Time Protocol
(SNTP) to obtain the current time from the internet, and broadcast the ASIC/1 and
ASIC/2 times periodically on the network. It also can correct for Time Zone and
Daylight Savings.
You must save any changes before changing to another screen.
SNTP time servers are ideally stand alone systems used by computers to receive time
from a time source. The SNTP server then sets and synchronizes the time on a
computer IT system or enterprise. Time can be passed from one time source to
another, typically starting from a reference clock (Stratum 0) connected to a Stratum
1 SNTP server. A time servers synchronized to a Stratum 1 server will be Stratum 2.
The further away a network is from a primary source, the greater the chance of signal
degradations due to variations in communications lines, and so forth.
1-10 •Configuring EtherLink/2 EtherLink/2 User Manual DOC-1643 (2008-09-16)

The Primary and Secondary SNTP Server IP are obtained from the internet. For
example from the NIST Internet Time Service. http://tf.nist.gov/service/its.htm .
The Time Zone refers to off set from Greenwich Mean Time:
Eastern Standard Time is GMT-5:00
Pacific Standard Time is GMT-8:00
The EtherLink/2 can synchronize an ASI Network at hourly intervals. The ASIC/1
Synchronize Address is typically the global address 23125, 0x5A55. . The ASIC/2
Synchronize Address is typically the global address 23152, 0x5A70.
The EtherLink/2 automatically corrects for Daylight Savings Time.
The DST Adjustment is usually +01:00 HH:MM.

ASI Software Connections
The EtherLink/2 supports both UDP/IP and TCP/IP connections. Access to a single
ASI serial bus can be shared to multiple remote users simultaneously.
The ASI OPC Server is usually the primary connection. If more than one Etherlink/2
is on the network then the primary connection should be via TCP/IP.
Like the EtherLink/1 before it, the EtherLink/2 can host only one TCP/IP connection
at a time. The TCP/IP connection is automatically reset after 15 seconds of
inactivity. Use of TCP/IP is recommended when you don't want to have to open up a
unique IP port on the host's firewall for each remote EtherLink/2.
While the EtherLink/1 could not host multiple connections, the EtherLink/2 adds
support for multiple simultaneous connections via UDP. If multiple EtherLink/2's
are connected to the same OPC server using UDP, then each EtherLink/2 must use a
unique IP port number so as to avoid traffic crosstalk. .
ASI Expert can also be used to connect to the Etherlink/2 as a secondary connection
using UDP. It is possible to have one or more Expert users connected to an
EtherLink/2 via UDP while an OPC Server is simultaneously polling that same
EtherLink/2 over TCP/IP.

OPC Server
When a front-end such as ASI WebLink is used, the ASI OPC Server establishes the
primary connection to the ASI Network. It can connect to any EtherLink/2 with
either TCP/IP or UDP.
Customers concerned with security should select TCP/IP, which can easily be
configured to work securely behind a firewall. The OPC Server can communicate to
over 100 EtherLink/2’s with unique IP addresses simultaneously using TCP on a
single IP port.
When using UDP, all EtherLink/2’s connected to a single OPC server will need to be
assigned unique IP ports, or the messages will collide. If UDP is not prohibited
because of the multiple IP ports, UDP can yield performance increases over TCP/IP
communications.
