General Overview

The iR1200 Modem is an iDEN data modem consisting of a modem card and an optional GPS (iR12000 GPS-Enabled Modem) receiver, contained in a rugged enclosure, to provide wireless data communications. The iR1200 modem is easy to mount, whether in a mobile or a fixed environment.

Figure 1. iR1200 GPS-Enabled Modem

RFM-4002-5015 Rev 3

iR1200 Modem

Modem Operating Modes

The iR1200 provides the following data connection modes:

• Packet Data: A wireless modem connection used for accessing the Internet, sending and receiving e-mail, and transferring small files over the packet data network using standard IP protocols.

Data is sent in packets (blocks) at high speed.

• Circuit Switched Data: A wireless modem connection for sending and receiving data (faxes, files, etc.) over the circuit-switched cellular channel, providing a direct point-to-point connection with the destination device.

Modem Configurations

Nextel offers two models of the iR1200 Modem. While both are designed to provide wireless communication for rugged environments, one model offers GPS capability as well.

The iR1200 modem can be purchased with the following configurations:

•

iR1200 Rugged Modem (Base Model) - Available in bulk or individual packaging

•

iR1200 GPS-Enabled Modem - Available in bulk or individual packaging

6 Insert the ignition bypass plug into the 4-prong polarized

IGNITION jack located on the rear panel of the modem (refer to Figures 2 and 3 on page 11).

7 The STATUS Led light will be solid RED. This indicates that

the modem is attempting to register with the iDEN network.

8 A blinking green light indicates that the modem has

successfully registered with the iDEN network.

Communication Indicators

Your iR1200 modem is equipped with the LED indicators (located on the front panel of the modem – see Figure 4) that identify various communication functions.

IMPORTANT INFORMATION: Customers cannot ping a Non Routable IP address when provisioned due to the NAT (Network Address Translator) Server. This server

attaches a Class C Public IP Address to a Private Class A Non Routable IP address for a specific period of time to browse the public internet. This Class C address is needed in order to route on the public internet, as Non-Routable IPs are for internal routing only (Intranet).

Mobile IP Activation

The modem makes use of mobile IP to manage a truly mobile computer. You may use a Mobile IP stack on the computer or use the Mobile IP stack built into the modem.

By default, the modem is configured to work with a third-party stack. If you desire this mode of operation, skip ahead to the “Configure Encryption Settings”. Otherwise, you must activate the Mobile Node functionality within the modem as well the security-related parameters.

NOTE: The Data Terminal Equipment (DTE) uses a TCP/IP stack to format the data message with standard TCP/IP protocols used on the Internet. The iR1200 modem does not have a TCP/IP stack. The “mobile-IP stack”

capability of the iR1200 is required to transmit data on the iDEN network.

S-Registers

In this chapter, you are will learn about S-registers and how to configure registers for your iR1200 modem.

This chapter includes:

S-Register Page 87 Programming S-Register Page 87 Reading S-Register Page 88 Supported S-Register Page 88

S-Registers

S-registers are memory locations in the modem that you can program to meet your communication needs. S-register parameters are numbered from 0 (zero) to 255. Since many of the registers are reserved for internal operation purposes, you are allowed to customize only a subset of the modem’s register.

Programming the S-Register

The following table describes the steps to program an S-Register.

1 From the command mode of your communication software,

type ATSn=x where n is the number of the S-register you wish to customize and x is the value that you wish to assign to that register.

2 Press ENTER to execute the command.

RFM-4002-5015 Rev 3

You may experience undesirable consequences if you modify the S7 or S10 registers from their set default values. For optimal performance, it is recommended that you use the default values set for these two registers.

Page 98

iR1200 Modem

If you write to an S-register that is not programmable or if the value you assigned is invalid, the modem will still return an OK message to the computer screen. The attempted changes will not affect the S-register values. .

Reading an S-Register Value

The following table describes how to read a value for an S-Register.

1 From the command mode, type ATSn (n= the number of

the S-register that you want to read) and press ENTER.

2 The value of the requested S-register displays.

NOTE: If you attempt to read the value of an S-register that is not

supported, the modem will display an ERROR message.

Supported S-Registers

The following table outlines the list of S-Registers that can be used to customize your modem.

0 Automatic Answer. Determines if the modem

automatically answers incoming calls.

• If the value assigned to this register is 0 (zero), the modem does not answer the call but sends an appropriate message to the computer that commands the modem to answer the call.

• If the value assigned to this register is a non- zero, the modem answers the call without waiting for the computer to issue its answer-call command.

12 Escape Code Timer. Determines the time duration

within which the escape code must be sent by the computer to escape from online command mode. The time (in seconds) the modem waits is determined by dividing the specific register value by 50.

Valid value ranges from 20 to 255. 50 or 1 second (50/50) is the default value.

30 Idle Timeout. Determines the amount of time that

the modem waits in online mode for a command from the computer before disconnecting the call and returning to command mode.
