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 iPocket232 in a network.
Features
The iPocket232 has many useful features, allowing you to:
• Replace an existing modem with the iPocket232 without making any other
changes to the network
• 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)

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.
NOTE: You can determine the IP address of your unit through the System Settings
menu, if it is a dynamically allocated (DHCP) IP Address, or a Static IP Address.
Please refer to 6.4: Display System Status for further information.
3.1.1 DHCP - Dynamic IP Address
DHCP (Dynamic Host Configuration Protocol) allows you to dynamically allocate IP
addresses to devices on a TCP/IP network.
NOTE: For further help on DHCP Administration, please refer to our DHCP Admin-
istrator Help Guide at http://www.precidia.com/products/documentation.html.
iPocket232s come configured with the IP address and subnet mask set at 0.0.0.0,
which automatically enables DHCP.
NOTE: The DHCP server must be on the same physical subnet as the iPocket232.
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

4.1 Protocol
The Protocol setting defines how the iPocket232 communicates with the remote
server. The Protocol setting has two parts: data formatting and 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.
IMPORTANT! The iPocket232 is a DCE device and therefore
cannot remotely control the DTR and RTS signals, nor monitor the
DSR, CTS, and DCD signals in compliance with RFC2217. Port
speed, parity, data width, and handshaking all function correctly.
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 iPocket232 extracts the command information from
the message and sets the following parameters of the serial port:
baud rate, data length, parity bits, stop bits, DSR signal, and flow
control.
Once the serial port is set, the iPocket232 forwards the data to the
serial device unchanged. If any changes to the Com Port or modem
line occur, the iPocket232 will automatically send a notification
packet to the host.
Once the transaction/transmission is complete, the iPocket232 automatically resets to the Port Setting defined in the
tings
sub-menu until the next message is received.

Telnet Com Port Control is defined in RFC2217.
If you are connecting only one iPocket232 to a PC and the application requires COM port connection, you can use Com Port Redirector software if your application is not affected by the limitations
noted above. You can find more information and purchase this software on the Precidia Web site at http://www.precidia.com/products/

iPocket232 User Guide 4 Configuring the Serial Port Settings
Table 4.1: Data Formatting Options
Menu Item Description
Telnet
Turns the iPocket232 into either a telnet client (most common use)
or a telnet server and allows the user to telnet out of the iPocket232
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
iPocket232 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 iPocket232 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 iPocket232 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 configure 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 Delay 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 4.11, Packet Prefix (Transparent Protocol Only)‚ on
page 34.

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 Terminators 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.
NOTE: 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 iPocket232 must be able to initiate
TCP connections and accept TCP connections from the host. In this
configuration, the iPocket232 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
necessary to match the Remote Port). Local Port and Remote Port
must be configured. Sections 4.6 through 4.10 describe how to configure ports and IP addresses.

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
iPocket232 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.
To set or change the Protocol:
1 Choose Serial Port from the Device Settings menu.
2 Choose Protocol from the Serial Port Settings sub-menu.
You are prompted to choose a new protocol, as shown below.

3 Type the letter (A to E), plus the number (1 to 4), that corresponds to your selection
and press Enter.
4.2 Port Setting
The serial port settings of the iPocket232 must match the settings of the attached serial
device to enable communication. Settings include bit rate, data width, error detect,
framing, and flow control.
NOTE: To avoid data loss, choose hardware flow control if you set the port speed to
19 200 bps or higher.
Choosing a Protocol

The flow control options are described Table 4.3 .
Table 4.3: Flow Control Options for Port Setting Parameter
Option Description
None
h/w
(rts/cts)
s/w
(xon/xoff)
Default
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 iPocket232 to start transferring data. If the remote end is
unable to accept the data as fast as it is received from the
iPocket232, the remote end negates CTS, and the iPocket232 suspends data transfer. When the remote end is ready for more data, it
asserts CTS again.
When the iPocket232 is ready to receive data, it asserts the RTS
signal. If the iPocket232 cannot accept data as quickly as the device
is passing data, it negates RTS. The iPocket232 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
iPocket232 or the remote host to signal the other end to start sending data. XOFF can also be used by either the iPocket232 or the
remote host to signal the other to stop sending data.
NOTE: 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.

NOTE: 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 iPocket232, 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) from 12- and
13-bit transfers.
4.3 Connection Control
Connection Control specifies the method of connection between the iPocket232 and
the remote serial device. The options are described in Table 4.4 .

Control
Links the protocol connection to the status of the network
(Ethernet). Attempts to keep the connection permanently open.
Uses the DTR/DSR lines to open and close connections. In tcpclient mode, the iPocket232 establishes an IP connection to the
remote host when DSR is asserted and terminates a connection
when DSR is negated.
In tcp-server mode, the iPocket232 asserts DTR when there is a
valid incoming connection attempt and accepts the connection as
soon as DSR is asserted.
In tcp(tunnel) mode the iPocket232 both accepts and establishes
connections to the host.
Uses the RTS/CTS lines to open and close connections. In tcpclient or tcp(tunnel) mode, the iPocket232 establishes an IP
connection to the remote host when CTS is asserted and terminates
a connection when CTS is negated.
In tcp-server or tcp(tunnel) mode, the iPocket232 asserts RTS
when there is a valid incoming connection attempt and accepts the
connection if CTS is currently asserted.
Modem
Enables the iPocket232 to act as modem to a device connected to
its serial port. The iPocket232 processes a superset of the standard
Hayes command set, including the ability to answer, dial, and originate a connection. FTP and HTTP are supported with extended AT
commands.

4.4 Terminal Type (Telnet Protocol Only)
If you select Telnet in the Protocol setting, you can enter the type of terminal you are
using. If the Terminal Type is unknown, this parameter may be left at (unset). The
telnet server will set a default type, but it is more effective to set it yourself. If the
terminal type is incorrect, the full screen telnet applications will not work properly.
To enter or change the Termina l Ty p e (Telnet only):
1 Choose Serial Port from the Device Settings menu.
2 Choose Terminal Type from the Serial Port Settings sub-menu.
You are prompted to enter the type of attached terminal, as shown below.
The "terminal type" is not simply an arbitrary string of characters describing
the type of device attached to the serial port. It is a specific name that
will be recognized by the remote host and used by it to decide how to control
that type of terminal.
Common terminal types are "dumb", "ansi", "vt100", and "vt102".

4.5 Local Port
Local Port is the port number that listens for incoming connections. This option must
be set if the iPocket232 will ever receive a session initiated from an outside source (in
tcp(tunnel), tcp-server, and udp modes). If the iPocket232 will only be used to initiate
sessions, this setting can be left at 0 (tcp-client mode).

You are prompted to enter the IP address of the remote system.
3 Type the remote IP address and press Enter.
4.7 Remote Port
Remote Port is the port address on the remote device to which the iPocket232 sends
incoming data. Remote Port must be set in tcp(tunnel), tcp-client, and udp modes.
To enter or change the Remote Port:
1 Choose Serial Port from the Device Settings menu.
2 Choose Remote Port from the Serial Port Settings sub-menu.
You are prompted to enter the port number on the remote system.
3 Type the remote port number at the prompt and press Enter.
4.8 Fallback IP
Fallback IP is the IP address of the machine the unit connects to if the Remote IP
address (primary) is not responding, not accepting connections, or not sending data.
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.

Setting the Terminators
The iPocket232 continues to capture data from the serial port into the receive buffer
until any one of six specific terminators is identified. Once this character is marked,
the iPocket232 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
Return is entered as 13. The most common terminators are listed in Table 4.6 .
NOTE: To use zero (null) as a terminator, you must set it as Terminator #1. Any zeroes
after the first terminator are ignored.
To configure or change the terminating characters:
1 Choose

You are prompted to enter a terminator character in decimal.
3 Type in a terminator and press Enter.
You are prompted to enter the number of tail bytes in decimal.
4 Enter the number of tail bytes and press Enter.
NOTE: The number of tail bytes determines how many characters to wait for after the
terminator before sending the packet.
For example, if you are parsing a data frame that ends with ETX and has a 2 byte CRC
that follows, you will want to terminate on 3, with 2 tail bytes. However, if you get an
ACK, you may not want to collect any tail bytes at all, so you would terminate on 6
with 0 tail bytes.

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 iPocket232 to two separate networks.
IMPORTANT! IPsec contains computationally intensive algorithms. Enabling IPsec
may cause a significant decrease in the speed/performance of the iPocket232. If your
application has performance or latency requirements, please ensure that this decrease
in performance does not break the timing requirements. Full baud rates may not be
achievable when IPsec is enabled.
To access the Secure IP Association settings you must first select an IPsec protocol.
23-CML000293 Precidia Technologies Inc. 43
Page 50
5 Configuring the Security Settings iPocket232 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 cryptog-
raphy 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.
Choose IPsec Tunnel #1 or IPsec Tunnel #2 from the Security Settings submenu.

The internal clock in iPocket232s will drift slightly over time. With SNTP configured,
the internal clock can be adjusted according to a central time server with an accuracy
of approximately 4 milliseconds.
iPocket232s only support SNTP in unicast mode. In unicast mode, the client
(iPocket232) sends a request to a designated server or servers and waits for a reply.
You can configure up to two SNTP servers. The iPocket232 will attempt to update the
internal clock every five minutes. If the unit is already connected to the network, it
will contact the first server. If the unit is not connected, it will wait until a connection
is established, contact both servers, and accept the first reply. If a reply is not received,
both servers will be contacted on the next attempt.
SNTP Settings
To configure SNTP:
1 Choose System Settings from the Device Settings menu.
2 Choose SNTP Settings from the System Settings sub-menu.
3 Choose Primary Server from the SNTP Settings sub-menu.
You are prompted to enter the IP address of the Primary Server as shown below.

Understanding the System Status Page
The System Status page is divided into three sections:
• System Uptime
•Serial Port
• Network Routing
System Uptime
This describes how long the system has been operational, the loading on the Precidia
device's CPU, and the firmware version of the iPocket232. Table 7.1 describes each
parameter:

7.3 Static Web Page
You can host static Web pages in the iPocket232 for displaying information such as
help desk telephone numbers or updates on the latest software downloads. The
iPocket232 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, including
graphics, that you require. The iPocket232 looks for a page called “index.html” as the
default main page to display. 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 Converting and Downloading Static Web Pages Help Guide at:
http://www.precidia.com/products/documentation.html for complete instructions.
Accessing the Static Web Page
1 Ensure the Web Server in the Security Settings sub-menu is enabled.
2 Open your browser.
3 Type http://IPaddressOfUnit/ in the address bar.
The static Web page appears.
NOTE: By default, your browser is directed to "index.html". To access a page with
another file name, type the complete URL in the address bar of your browser. For

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.)
4 Check the indicator lamps on the front panel of the unit and use the indicator
lamp tables in this appendix to diagnose the problem.
5 If, after following the suggestions in this guide, you are still having problems
accessing configuration or gaining connectivity, you can contact Precidia support.

Check IP Address (Ping)
Use ping to check if the iPocket232 is correctly configured on the network. If you
cannot reach the iPocket232 using Ping, the iPocket232 is either incorrectly
configured or there is a network problem.
To “ping” the iPocket232:
1 Open the MS-DOS Prompt. (Usually found under Start>Programs)
2 At the C:\WINDOWS> prompt type ping and the IP address you want to
check.
- If you get Reply messages, the iPocket232 has a valid connection to the
network.
- If you get a Request timed out message, the iPocket232 is incorrectly
configured with the IP address, or you have a network connection
problem.
NOTE: You can also use ping to check if an IP address is already in use on your
network, before assigning it to a new unit.

Modem Connection Control is available with the Precidia’s Remote Access products. The iPocket232 is slightly different since it is a DCE device and drives the
DCD signal. When you choose
the iPocket232 behaves like a Hayes, or “universal” modem to the device
connected on its serial port. The connected serial device (DTE) receives the
expected modem replies when communicating with the iPocket232. For further
information on setting Modem Connection Control, see “Connection Control” on
page 27.
iPocket232 Modem Overview
AT commands direct a modem to dial, answer, hang-up, and perform many other
communication tasks. All commands listed, except A/ and +++, must be
preceded by AT, followed by a carriage return. You can include multiple
commands on a command line, as long as the command does not exceed 80 characters when including the prefix and carriage return. Spaces are ignored.
Commands following a command that opens, or closes an active connection, are
ignored.
Modem as the method of Connection Control,
A Dial command (ATD) instructs the modem to attempt a connection to the specified IP address and port number, or, if none is specified, to the configured
Remote IP in the Serial Port Settings sub-menu.
An On-Line command (ATO) instructs the modem to return to its active connection. If there is no active connection, the modem attempts to establish one using
the configured Remote IP and Remote Port.
An Answer command (ATA) instructs the modem to listen on a specified port
number. If no port number is specified, the configured local port number is used.
If the local port is not set, the standard telnet port (23) is used.
The escape sequence (+++) causes the modem to return to command mode from
answer or dial states, keeping the active connection open. An on-off transmission
on the DTR line also causes the modem to return to command mode. In this case,
the active connection may be maintained or closed, depending on how AT&D2 is
defined.
23-CML000293 Precidia Technologies Inc. F-1
Page 94
Appendix F: MCC iPocket232 User Guide
The modem must be in command mode to receive commands. Any command,
other than the escape sequence (+++), that is sent to the modem while it is in
transmission mode, is transmitted as data.
NOTE: If any characters arrive from the DTE while the modem is executing a
command, such as ATA or ATD, that command is aborted.
Supported AT Commands
Precidia supports a subset of the standard Hayes command set, and a selection of
extended commands, including the ability to initiate and perform FTP and HTTP
transfers (see page F-10).
NOTE: You can test the iPocket232 modem, when not in configuration mode, by
typing AT commands in your terminal software (HyperTerminal, Procomm Plus).
NOTE: Only the options listed under Parameters are valid. Any unsupported
standard command options return an OK result. Any unsupported non-standard
commands return an error result. Options not required are ignored.
The following two tables describe the supported standard AT commands and the
extended AT& and AT+ commands:

A[pppp] ANSWER
Description Parameters
Allows the iPocket232 modem to listen for a connection, or accept a connection on the provided port
[pppp].
Successful connection returns a “CONNECT
<speed>” message. Otherwise, the modem waits
indefinitely, or until a key is pressed to cancel.
If no port number is specified, the modem uses the
configured Local Port. If Local Port is 0, the modem
uses the standard telnet port (23).
The modem provides a “RING” message when an
incoming connection is received and auto-answer is
not active.
NOTE: A telnet program is already listening on port
23 if the Remote Password has been set. If this
command is also input, you will get an “ERROR”
message.

Escape to Command Mode
The modem can be moved into command mode in one of two ways: sending the
sequence (pause, +++, pause) to the serial port, or dropping the DTR signal
(AT&Dn).
The first method, sending an escape sequence, moves the modem into command
mode but keeps the connection active. The default escape character is “+” and is
stored in register S2. The default pause value is the value of register S12 (20)
multiplied by 20ms. You can change the defaults by setting the registers with
your own values.
string =
ftp://[userid[:password]@]ipadr[:port]/path/file.ext

ftp://[userid[:password]@]ipadr[:port]/path/file.ext
23-CML000293 Precidia Technologies Inc. F-7
Page 100
Appendix F: MCC iPocket232 User Guide
The second method, dropping the DTR signal, is not supported by hardware platforms that do not have a wire for the DTR signal. Additionally, the reaction to the
DTR signal depends on how you configure the DTR setting using the &Dn
command. See &Dn on page E-4 for DTR settings.
S-Registers
Basic S-registers (S0–S12) store information used by the modem and communication software. Basic S-registers have predefined values. Extended S-registers
(S13+) are used for storing command option values. The following table summarizes the values and purpose of Precidia-supported S-registers.
