1.2 Functionality and Features
How It Works
The Cell232Plus connects serial devices to IP networks via existing wireless digital
networks. The serial device sends information to the Cell232Plus through the RS-422/
485 or COM port. This information is processed according to the protocol set in the
Serial Port Settings, then transferred to the modem side of the Cell232Plus.
The Cell232Plus converts the information to IP format and sends it out through the
MODEM port to the receiver or handset according to the parameters set in the
Network Port Settings. The cellular phone provides immediate access to the wireless
digital network and through the terrestrial IP network to the transaction processor
(remote server).
This process is reversed when information is received from the remote server. The
figure below illustrates an example configuration of the Cell232Plus in the network.
Cell232Plus — Network Configuration

• Transparent to existing serial connections
• Compatible with TCP/IP networks for Internet and Intranet applications
• Built-in static and dynamic Web pages accessible locally or via Web browser or
telnet

• Auto-identity header
• Works with Com Port Redirection
• ATM Modem emulation software
• Routing redundancy incase of application server failure
• Local and remote configuration and software upgrade capability

• Control and refine connection settings with options that include:
- Automatic connection in tcp(tunnel) and tcp-client modes to establish a
connection to the server as soon as the first data byte is received on the serial
port
- Connection recovery to ensure the session remains active
- COM Port Redirector Software compatibility using the Com Port Control
protocol option
- Modem Connection Control that allows the Precidia unit to appear as a Hayes-
compatible modem to your serial device
• Connect an RS-422/485 device or an RS-232 device to one of two ports
• Support the following network protocols:

Indicator Lamp Description
ON Illuminates constantly when power is applied to the unit.
— MODEM —
CARRIER Illuminates when the unit has a connection to the cellular
phone, will stay illuminated when the cellular phone has a
valid connection to the service provider.
RECEIVE Illuminates when the unit is receiving data through the
MODEM port from the cellular phone. Lamp flashes to indi-
cate this activity. Lamp will flash for up to 15 seconds on
power if you have not yet configured the Modem Dial number
(PPP-Dial Up Settings) to dial the host.
TRANSMIT Illuminates when the unit has control of the line and is send-
ing data through the MODEM port to the cellular phone and
wireless connection. Lamp flashes to indicate this activity.
Lamp will flash for up to 15 seconds on power if you have not
yet configured the Modem Dial number (PPP-Dial Up Set-
tings) to dial the host.
— COM —
TRANSMIT Illuminates when the unit is sending or receiving data out the
COM port. Lamp flashes to indicate this activity.
Illuminates constantly while in configuration mode.
STATUS Off: Unit incorrectly configured or the COM port is disabled.
Slow flash: Correctly configured, in idle mode.
Fast flash: Correctly configured, terminal has communicated.
On (solid): Correctly configured, connected.

The Precidia package includes:
• one (1) power adapter
• one (1) Cell232Plus device
• one (1) Warranty Card
To complete the installation you also need:
• one (1) PC with terminal software, or a dumb terminal for configuration
• one (1) cellular phone with “always on” digital network access service agreement
• one (1) standard PC-to-cell phone data cable with DB-9 connector from your
cellular phone manufacturer
• If you are connecting the Precidia unit to a DTE (Data Terminal Equipment)
device:
- one (1) null modem serial cable for configuration and for connecting your DTE
serial device after configuration
Table 1.2: Back Panel Ports
Port Description
POWER Accepts the Precidia-supplied 9V power adapter.
CONFIGURE Press and hold the recessed CONFIGURE button for
several seconds to activate local configuration through
the COM port.
RS-422/485 RS-422 or RS-485 mode only: Accepts RS-422 or
RS-485 serial cable.
MODEM Accepts DB-9 data cable connected to a cellular
phone.
COM Accepts DB-9 null modem serial cable for configura-
tion.

• If you are connecting the Precidia unit to a DCE (Data Communication Equip-
ment) device:
- one (1) null modem serial cable for configuration
- one (1) RS-232, RS-422, or RS-485 serial cable for connecting your DCE serial
device to the Cell232Plus
TIP: How do you know if your serial device is DCE or DTE?
• DCE devices generally have a female (receptacle) DB-9 connector. Examples of
DCE devices include modems, Digital Service Units (DSU), Channel Service
Units (CSU), and most communications equipment.
• DTE devices generally have a male (pin) DB-9 connector. Examples of DTE
devices include communications servers, terminals, serial printers, and PCs with
native RS-232-E serial ports.
Reconfiguration
After your Precidia unit is operational you will require one null modem serial cable
and a PC or dumb terminal to locally reconfigure the unit.
NOTE: If you know the IP address of the Precidia unit and have set the Remote Pass-
word, you can reconfigure remotely using telnet. See the Help Guide Connecting with
Telnet at http://www.precidia.com/technical_support/manuals.html.
1.5 Software Requirements
You will need terminal software (or a dumb terminal) to locally configure the unit. Try
HyperTerminal, which comes with Windows, or Procomm Plus (Symantec).
1.6 Configuration Requirements
The following settings are the basic requirements for configuring the unit. You may
need to configure other settings depending on your set-up and the Protocol you are
using.
PPP Dial-Up Settings
• Modem Init: the initialization string for the modem
• Modem Dial: the phone number of the ISP (Internet Service Provider) for the
modem to dial
• Login Userid and Login Password: the login information from your ISP or VPN
provider

3Connect the cell phone data cable to the activated cellular phone if you have not
already done so.
4Ensure the CARRIER lamp is lit to indicate a valid wireless connection and the
STATUS lamp is flashing to indicate the unit is ready to transmit/receive data.
2.2 Setting Up the Terminal
Once the Precidia unit is connected to your PC, you can access the Configuration
screen using terminal software.
If you do not have terminal software you can use HyperTerminal, which comes stan-
dard with every Windows PC. If necessary, refer to the Help Guide Working With
HyperTerminal at http://www.precidia.com/technical_support/manuals.html.
NOTE FOR WINDOWS XP/2000 USERS: To perform firmware upgrades or
download static Web pages to the Precidia unit using HyperTerminal, you need to
upgrade to the latest version. Obtain your free HyperTerminal upgrade from
http://www.hilgraeve.com/.
1Start your terminal program.
2Select the correct COM port in your terminal software (usually Com1 or Com2).
3Configure the terminal with the following settings:
• Bits per second: 9600 (required)
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: Hardware
NOTE: The Data Bits, Parity, Stop Bits, and Flow control settings listed above are
recommended settings. Configuration can be accessed using any settings at 9600 bps.
