1.2 Functionality and Features
How It Works
Precidia products connect serial devices and IP networks. A device sends information
to the unit through the serial port. This information is processed according to the
protocol set in the Serial Port Settings, then transferred to the Ethernet side of the unit.
The unit then converts the information to IP compatible format and sends it out the
Ethernet port to the remote server according to the parameters set in the Ethernet
Settings. The process is reversed when information is received from the remote server .
The figure below illustrates an example configuration of the Ether232PPlus in a
network.
Ether232Plus — Network Configuration
Features
The Ether232Plus has many useful features, allowing you to:
• Configure settings locally via the COM port or remotely using telnet
• Display static Web pages using a built-in Web page server
• Display dynamic System Status and System Log pages through the built-in Web
server or the Configuration screen
• Manage information with SNMPv2c (Simple Network Management Protocol)
• Tap remotely into the datastream to monitor data and assist in debugging
• Provide security through passwords and IPsec
• Use a primary and a backup server (automatic switchover on failure)
• Capture statistics and log system information internally
• Upload firmware upgrades using TFTP (Trivial File Transfer Protocol) or via the
local com port

3.1 IP Address
An IP address is an identifier for computers or devices on a TCP/IP network. Make
sure that the IP address you assign is not in use by any other device on your network.
IP addresses are made up of four numbers from 0 to 255, separated by periods.DHCP -
3.1.1 Dynamic IP Address
DHCP (Dynamic Host Configuration Protocol) allows you to dynamically allocate IP
addresses to devices on a TCP/IP network.
OTE
N
: The DHCP server must be on the same physical subnet as the Precidia unit.
OTE
N
: For further help on DHCP Administration, please refer to our DHCP Admin-
istration Help Guide at http://www.precidia.com/products/documentation.html.
Precidia units come configured with the IP address and subnet mask set at 0.0.0.0,
which automatically enables DHCP configuration. If you are using a DHCP server,
leave all Ethernet Settings at zero (0.0.0.0). The settings will always appear as zeros
in the menu regardless of the values assigned by the DHCP server.
The DHCP assigned IP addresses can be viewed in the unit’s System Status. Follow
the steps in 6.4, Display System Status to view the status information.
The first Local address listed under Network Routing is the IP address of the unit.
To enable DHCP configuration:
1 Choose
Ethernet Settings
from the Device Settings menu. (If the IP Address and
Subnet Mask are both 0.0.0.0, then DHCP is already enabled.)
2 Choose

3.4 Additional Gateway
The Additional Gateway option allows you to specify a second gateway (router) for a
specific network address.
You can use the Additional Gateway to run the SNMP (Simple Network Management
Protocol) manager on a computer on another network. You can also telnet to the
Precidia unit, or ping to check its status, from a computer on another network. In this
way, if your primary network goes down, you can still access the Precidia unit and
remotely reconfigure it to another network.
OTE
N
: The Additional Gateway must be on the same subnet as the device.

4.1 Protocol
The Protocol setting defines how the Ether232Plus communicates with the remote
server. The Protocol setting has two parts: Data formatting an Session Mode.
The first part of the Protocol setting, data formatting, indicates how to parse or
process the data stream to provide compatibility with the remote server. Table 4.1
describes the data formatting options.
Table 4.1: Data Formatting Options
Menu Item Description
disabled
ComPort
Control
Default setting. The unit will not accept any host initiated or local
sessions. You must choose a protocol for the unit to become active.
Extends a serial link to allow remote configuration and control of a
serial port. Upon receipt of a message containing Com Port Control
commands, the Ether232Plus extracts the command information
from the message and sets the following parameters of the serial
port: baud rate, data length, parity bits, stop bits, DTR signal (often
used to disconnect a call), and flow control.
Once the serial port is set, the Ether232Plus forwards the data to the
serial device unchanged. If any changes to the Com Port or modem
line occur, the Ether232Plus will automatically send a notification
packet to the host.
Once the transaction/transmission is complete, the Ether232Plus
automatically resets to the Port Setting defined in the Serial Port
Settings
sub-menu until the next message is received.
Telnet Com Port Control is defined in RFC2217. Refer to the Help
Guide Com Port Control Compliance at http://www.precidia.com/
products/documentation.html for a list of the Com Port Control
commands supported by the Ether232Plus.
If you are connecting only one Ether232Plus to a PC and the appli-
cation requires COM port connection, you can use Com Port Redirector software. You can find more information and purchase this
software on the Precidia Web site at http://www.precidia.com/prod-
ucts/request_software.html.

Ether232Plus User Guide 4 Configuring the Serial Port Settings
Table 4.1: Data Formatting Options
Menu Item Description
Telnet
Turns the Ether232Plus into either a telnet client (most common
use) or a telnet server and allows the user to telnet out of the
Ether232Plus to a remote server, such as a UNIX workstation.
The standard connection control options are supported. By leaving
the Connection Control parameter at Automatic (default setting),
the user can initiate the telnet session by pressing any alphanumeric
key. If the Connection Control parameter is set to DTR/DSR Control, the Ether232Plus tries to open a telnet session as soon as DSR
is detected from the terminal, but the timeout function of most hosts
makes this option somewhat unreliable.
Telnet-Client: The most common use of the telnet protocol. To create a telnet client, select tcp-client as the session mode. This configuration allows the Ether232Plus to communicate with the telnet
server at the configured Remote IP address and Remote Port.
Telnet-Server: To create a telnet server, select tcp-server as the
session mode when configuring this protocol. The Ether232Plus listens on port 23, and the Remote Password must be disabled so that
the standard configuration program is not listening on that port. You
can still use a Remote Password by configuring Telnet to listen on a
port other than 23 (but above 1024 to avoid using reserved ports).
Transparent
Typical setting. No alterations are made to the data stream, nor is it
parsed in any way. Data is collected until either the preferred packet
size is reached or there is a pause between characters that exceeds
the inter-character timer. The buffer is then transmitted as a single
frame. Preferred Packet Size and Max Inter- Char De lay can be left
at the default settings (0), and the unit will automatically determine
a reasonable setting based on the current serial port speed.
Transparent protocol includes the option Packet Prefix, which
allows you to include a header in the packet defining it’s length. See
Section 4.12, Packet Prefix (Transparent Protocol Only)‚ on
page 35.

4 Configuring the Serial Port Settings Ether232Plus User Guide
Table 4.1: Data Formatting Options
Menu Item Description
Terminated
No alterations are made to the data stream, but incoming data is
checked for known "end-of-record" characters, or "terminators",
that identify the end of a block so that it can be transmitted as a
whole to the remote host. If this mode is selected, you will be
prompted to enter up to six T erminators in their ASCII decimal form
(e.g. <CR> = 13). This is ideal when the host requires pre-parsing of
the data, such as with an AS/400.
OTE
N
: To use zero (null) as a terminator, you must set it as Termi-
nator #1. Any zeroes after the first terminator are ignored.
The second part of the Protocol setting, session mode, determines how the data
channel between the terminal and the server is established. Communications between
the device and the host can be over TCP or UDP channels. In addition, the device can
initiate a session immediately or wait until either the server (host) or the terminal
(client) attempts to establish a connection. Table 4.2 describes the session mode
options.
Table 4.2: Session Mode Options
Menu Item Description
tcp(tunnel)
Typical configuration for most applications. Use tcp(tunnel) mode
when the Ether232Plus must be able to initiate TCP connections and
accept TCP connections from the host. In this configuration, the
Ether232Plus can communicate with the TCP/IP host as if it were
virtually connected. Local Port, Remote Port, and Remote IP must
be configured. Sections 4.6 through 4.10 describe how to configure
ports and IP addresses.
tcp-client
Use tcp-client mode when all transactions must be initiated by the
terminal. This ensures that a TCP/IP host (server) can never initiate
communications with the terminal.
tcp-server
Use tcp-server mode when the TCP/IP host must never be interrupted by the terminal unless it authorizes a connection. This
ensures that data from the terminal will be discarded until the server
establishes a session. As a security feature, the host address must
match the Remote IP configured in the Serial Port Settings. Local
Port and Remote Port must be configured. Sections 4.6 through 4.10
describe how to configure ports and IP addresses.

Table 4.2: Session Mode Options
Menu Item Description
udp
Similar to tcp(tunnel) mode, use UDP mode when reception
acknowledgement of the data packets is not required. UDP is a connectionless channel, therefore, it is not necessary to initiate or accept
connections. This makes for slightly faster data flow. Setting the
Remote IP address to all zeros puts UDP into "reply mode" and the
Ether232Plus will send data to the last address it received data from.
For peer-to-peer communication, the host address must match the
Remote IP defined in configuration.

Table 4.3: Flow Control Options for Port Setting Parameter
Option Description
None
h/w
(rts/cts)
s/w
(xon/xoff)
Default setting. No flow control enabled. Data may be lost due to
overflow during high speed communication.
Hardware handshaking uses the RTS/CTS (Request To Send/Clear
To Send) signal lines for flow control on the COM port. Hardware
handshaking works by altering voltage levels on these lines. When
the remote end is ready to receive data, it asserts the CTS signal to
tell the Ether232Plus to start transferring data. If the remote end is
unable to accept the data as fast as it is received from the
Ether232Plus, the remote end negates CTS, and the Ether232Plus
suspends data transfer . When the remote end is ready for more data,
it asserts CTS again.
When the Ether232Plus is ready to receive data, it asserts the RTS
signal. If the Ether232Plus cannot accept data as quickly as the
device is passing data, it negates RTS. The Ether232Plus asserts
RTS again when it is ready to resume receiving data. This setting
can be used for the majority of installations.
Software handshaking requires that XON/XOFF characters are
asserted and obeyed on the COM port. XON is used by either the
Ether232Plus or the remote host to signal the other end to start
sending data. XOFF can also be used by either the Ether232Plus or
the remote host to signal the other to stop sending data.
OTE
N
: XON/XOFF characters included in a data transmission are
interpreted as flow control characters and will cause transmission
problems. This option is not recommended for binary data transmission.

: Serial ports communicate using the RS-232 serial (bit-stream) protocol. Each
byte of data transferred through the serial port consists of a predetermined number of
bits: 1 start bit, 7, 8, or 9 data bits, 1 or no parity bit, and 1 or 2 stop bits, for a total
between 9 and 13 bits. The port configuration “8E2”, for example, results in a 12-bit
data length consisting of 1 start bit + 8 data bits + 1 parity bit + 2 stop bits. Serial
ports on the Precidia unit, however, support only 10- and 11-bit transfers. Port
configurations of 9, 12, or 13 bits are automatically converted by adding an extra stop
bit to 9-bit transfers, and dropping stop bits and parity bits (if necessary) fr om 12- and
13-bit transfers.
4.3 Port Mode
Port Mode specifies the type of serial connection the Precidia unit has with the serial
device. You can choose from RS-232, RS-422, or RS-485, according to the type of

host when DSR is asserted and terminates a connection when DSR is
negated.
In tcp-server mode, the Ether232Plus asserts DTR when there is a
valid incoming connection attempt and accepts the connection as soon

The unit makes one attempt to connect to the Remote IP. If that attempt fails, it
attempts to connect to the Fallback IP, alternating until a connection is made. After
connecting to the Fallback IP address, the unit tries the Remote IP on the next attempt.
If data is received from either host, the next connection attempt is to the Remote IP
address.
Fallback can also be disabled, or enabled to accept incoming connections from any
host. Table 4.5 describes Fallback IP settings.

until any one of six specific terminators is identified. Once this character is marked,
the Ether232Plus continues to capture a configurable number of characters (tail bytes),
then terminates the frame and transmits it to the host.
Terminators must be specified in their ASCII decimal form. For example, Carriage

5.8 IPsec Tunnels #1 and #2
IPsec (Internet Protocol security) refers to a set of specifications for security at the IP
layer of TCP/IP networks. IPsec tunnels are special secure channels of communication
encapsulated within IP protocol that encrypt both the payload data and the packet
header. Encapsulated Secure Payload (ESP) for IP is defined in RFC1827. You can
define up to two tunnels to securely connect the Precidia unit to two separate
networks.

I
may cause a significant decrease in the speed/ performance of the Pr ecidia unit. If your
application has performance or latency requirements, please ensur e that this decr ease
in performance does not break the timing requirements. Full baud rates may not be
achievable with IPsec enabled.
To access the Secure IP Association settings you must first select an IPsec protocol.
! IPsec contains computationally intensive algorithms. Enabling IPsec
02-CML000057 Precidia Technologies Inc. 43

5 Configuring the Security Settings Ether232Plus User Guide
Protocol
The IPsec protocol defines the method of encryption and authentication to use through
the IPsec tunnel. You can choose between two modes: DES-MD5-96 or 3DES-MD5-
96. Encoding is provided by DES (Data Encryption Standard), a secret key cryptography method. DES uses a 56-bit key, while 3DES (tripleDES) uses a 168-bit key.
Authentication is provided by MD5 (Message Digest 5). The message digest allows
the receiver of a packet to ensure that a packet has not been altered en route from the
sender. MD5 is described in RFC1321.

6.7 Perform Self Test
Perform Self Test is a troubleshooting aid that performs a check on the unit’s memory
I/O system. You will not need to use this feature during the normal course of operation. The self-test takes a few minutes to run and the unit is unable to process any
information during this time.
To run Perform Self Test:
1 Choose
Perform Self Test
from the System Settings sub-menu.
You are prompted to continue with the Self Test or not, as shown below.
During a self test, the system will not be available for normal operations
and data processing until after all tests are complete. This will take a
few minutes. Are you sure this is what you wish to do? (y/n)

6.8 Reset Unit
Reset Unit is useful for troubleshooting, since it allows you to ensure that modem
connections are dropped correctly. Reset Unit resets the Ether232Plus, and drops all
active modem connections. The Configuration screen is not changed nor is the System
Log cleared, however, the message “===== Ether232Plus Started =====” is appended
to the System Log.
Everything is fine
A transmitted character was not received
The internal port could not transmit
No loopback dongle found
The DTR/DSR, DTR/DCD lines, if
present, are not looped back as expected
The data sent is not the same as the data
received
Reset Unit allows you to reset the Ether232Plus from a telnet session without saving
any changes to the configuration menu.

7.3 Static Web Page
You can host a static Web page or pages in the Precidia unit to display information
such as help desk telephone numbers or updates on the latest software downloads. The
Precidia unit comes loaded with a default static Web page that includes specifications
and product information.
Creating Static Web Pages
You can create one or more HTML pages that display any information that you
require, including graphics. The Precidia unit looks for a page called “index.html” as
the default main page. In addition to your main page, you can also create a custom
page called “Error404.html” that is displayed when a requested URL is not found. A
maximum of 64KB is allocated in memory for static web page(s). HTML pages and
associated files must be converted to a hex file format for download.
Refer to the Help Guide Coverting and Downloading Static Web Pages at
http://www.precidia.com/products/documentation.html for complete instructions.

on the following page (B-2) to troubleshoot Configuration screen access.
2 Ensure that you are using the correct serial cables and that all cables are prop-
erly connected and in good working order.
- If you are connecting the Precidia unit to a DTE (Data Terminal Equipment) device, use a null modem serial cable.
- If you are connecting the Precidia unit to a DCE (Data Communication
Equipment) device, use an RS-232 serial cable.
- If you are connecting the Precidia unit as a Hayes-compatible modem, or
to a Hayes-compatible modem, use a specialized null modem serial cable.
See “Specialized Null Modem Serial Cable” on page E-1. Some POS
terminals may also require this type of cable.
3 If you know the IP address of the unit, you can check the network connection
by pinging the unit. (See Check IP Address (Ping) on page B-3.)

Check IP Address (Ping)
Use ping to check if the Precidia unit is correctly configured on the network. If you
cannot reach the Precidia unit using Ping, the Precidia unit is either incorrectly configured or there is a network problem.
To “ping” the Precidia unit:
1 Open the MS-DOS Prompt. (Usually found under Start>Programs)
2 At the C:\WINDOWS> prompt type
- If you get Reply messages, the Precidia unit has a valid connection to the
network.
- If you get a Request timed out message, the Precidia unit is incorrectly configured with the IP address, or you have a network connection problem.
