1Introduction

Thank you for purchasing the Land-Cellular CDM819s or CDM819u (herein after referred to as

the CDM-819s/u) wireless modem. This guide will assist you in the set up and use of your new

CDM-819s/u modem. Follow the instructions in sections 2, 3 and 4 to install all necessary

software/drivers and set up your computer or data terminal to send and receive information via

the cellular network.

This manual is written for CDM-819s/u modems that have an RF module with a firmware version

of LF1.2.04 and LF1.2.06. The firmware version of the module can be confirmed with the

AT+GMR command. This command works with all firmware versions of the RF module.

1.1 Modem Capabilities

The CDM-819s/u automatically supports dual-band operations in the CDMA 800MHz cellular

and CDMA 1900MHz PCS bands.

The modem has three operational states:

Command State

Online State

Online Command State

When first powered on, the modem is in the Command State where it is able to accept AT

commands. When instructed to dial out or to answer a data call, the phone is in the Online State.

The "Quick Reference Guide",section 11.0 has more information on how to enter these

operational modes

1.2 The Types Of Calls

This chapter describes some of the features and capabilities of the CDM-819s/u modem. Section

2 explains how to set up your modem to place data calls using HyperTerminal and Dial-Up

Networking. Understanding these methods may help you to integrate the module with other

systems as well.

The modem can make three types of calls:

Mobile Circuit Switch Data (Origination and Termination)

Mobile Packet Data (TCP/IP Origination and Termination), TCP and UDP

Voice Channel

1.3 Speeds

Data Rate From The Modem To The Cellular Network

Data rates for Circuit Switch Data calls are up to 14.4 kbps, whereas 1xRTT Packet Data Calls

(TCP/IP) supports data throughput up to 153.6 kbps.

Data Rate From Your Computer To The Modem

The CDM-819s/u modem has a default RS-232 port speed of 115,200 bps. Your COM port must

be configured to operate at this rate in order to properly communicate with the modem. The

modem's COM port speed can be adjusted with the: AT+IPR command. The modem's COM port

speed is variable from 300 bps to 230,400 bps. Warning: Please ensure your COM port is

capable of 230,400 data rates before changing the modem to this speed, or you may not be

able to talk to the modem.

2Getting Started

The following Fast-Track Sections details how to quickly activate a modem, configure and test a

Circuit Switch Data (CSD) call, and a Packet Data Call (TCP/IP). Additional details if needed are

listed in the sections that follow the Fast-Track Sections. The following modem setup examples

apply for Windows 98, Me, NT, 2000 & XP®. Due to the divergent graphical interfaces of these

different operating systems, there may or may not be an extra step to follow (e.g. an additional

procedure to open a program from the Start Menu). This guide is optimized for Windows XP

Professional.

2.1 Fast-Track: Circuit Switch Data (CSD) Call Setup

1. Connect the modem to an active COM port on a PC with an RS-232 9 pin straight

through cable.

2. Attach the antenna and power connector.

3. Connect with a Hyper-Terminal session set to 115,200, 8 Bits, No Parity, 1 Stop Bit, and

Hardware Flow Control enabled, the default speed of the modem.

4. If the modem has not been activated, activate the modem. See Section 2.3 and the

Appendix for information specific to your carrier.

5. Change the Baud Rate to your required speed, i.e. 9600. AT+IPR=9600. Disconnect

HyperTerminal, change the baud rate to 9600 and reconnect.

6. Confirm contact with modem using AT+GSN this prints out the ESN of the modem (i.e.

+GSN: 45263AF4). If you get an Error or no communication, go to the section 2.4

Troubleshooting Communications with the Modem.

7. To auto-answer calls set ATS0=1 A value of ATS0=1 sets the modem to answer on the

first ring, where ATS0=0 disables the auto-answer feature. (Note this is a letter S

followed by a Zero)

8. Set the modem to answer/terminate incoming Asynchronous Data Calls; AT$QCVAD=4

9. To set the Carrier Detect (DCD) to follow its connection state to the Cellular Network, set

AT&C1. The yellow LED will turn on when connected to the Carrier, and turn off when not

connected. A value of AT&C0 sets CD to always be on, and a value of AT&C2 sets CD

to be always on, but to wink when there is a change in the connection state.

10. Ensure that DTR is set to return to modem to command state on an ON-to-OFF transition

of DTR with AT&D2 A value of AT&D0 ignores DTR, a value of AT&D1 enters

online command state upon an ON-to-OFF transition of DTR.

11. Save the new settings in Profile 1 with AT&W1 and then set Profile 1 as the Default

profile with AT&Y1

12. To confirm your settings, do an AT&V. This will print out about 7 lines of text with all the

13. Verify that you have good signal strength, AT+CSQ?. A typical reply is +CSQ? 19,99.The

signal strength ranges from 0 to 31, the higher the number the better the signal.

14. Set the modem for verbose result codes, with ATV1, this displays result codes as Words,

ATV0 displays result codes as digits.

15. Confirm and that you are registered on the cellular network. AT+CSS? A reply of +CSS?

2,Z,99999 indicates that you are not registered. It may take up to 15 seconds or so after

power-up to register on the network. Once registered a typical response will be +CSS?:

1,A,4152 where 1 is the band class, 1=800 MHz, 2=1900 MHz, A-F is the band (Z

indicates not registered on network), 4152 is the SID, i.e. the cell tower ID, (99999

indicates not registered on network).

16. Test CSD Origination by calling your cell phone with ATDT5551234567 (replace

5551234567 with your cell phone number). Once the phone rings and you answer the

phone, you should hear sounds like a fax negotiation.

17. Test CSD Termination by calling the phone number of your modem. Once it answers

you should hear sounds like a fax negotiation. Hang up.

18. To further test CSD termination connect another modem, (landline or cellular) to another

available COM port on a PC. Configure that modem and the COM port to your required

speed, i.e. 9600, with AT+IPR=9600.

19. Start HyperTerminal on that PC’s COM port and call the Land-Cell modem from this

terminal window with the following command. ATDT<Phone number of 819 Modem>.

20. The terminal window connected to the 819 modem, will say “RING” and then once the

modems have negotiated a connection, it will say “CONNECT”.

21. You can now type in text in either terminal window and it will appear in the other terminal

window. This means that your modem is now answering incoming CSD data calls.

22. Type in ATH0 to disconnect the call.

23. Once you can originate and terminate CSD calls with the modem you are ready to

connect the modem to your equipment. Please ensure that your equipment is configured

to your required data rate, i.e. 9600 bps.

24. By default the Modem is configured for full hardware flow control. This uses the control

signals, CTS and DTS, DSR and DTR, Carrier Detect, and Ring Indicator. The pin-out of

the modem is in Section 12.

25. If you are using a 3 wire interface cable with RX, TX and Ground or your equipment is

configured for no hardware flow control, you will need to disable Hardware flow control

with AT+IFC=0,0 and save it in your profile with AT&W1.

26. If your equipment cannot disable hardware flow control, you can spoof the signals by

shorting pins 1,4 and 6 together, and also pins 7 and 8 on the DE-9 connectors of your

three-wire cable.

2.2 Fast-Track: Packet Data Call Setup

1. Create a 19,200 Generic Modem and configure it for 115,200, 8 bits, no parity, 1 stop bit.

Attach the modem to an active COM port on the PC, i.e. COM1.

2. Configure the selected COM port to a maximum speed of 115,200 in the Hardware

device manager.

3. Attach the antenna and power to the CDM-819 modem.

4. Connect it to the COM port with a 9 pin RS-232 straight through serial cable.

5. If the modem has not been activated, activate the modem. See Section 2.3 and the

Appendix for information specific to your carrier.

6. Use HyperTerminal on the COM port to set the Carrier Detect (DCD) to follow its

connection state to the Cellular Network, set AT&C1. The yellow LED will turn on when

connected to the Carrier, and turn off when not connected. A value of AT&C0 sets CD to

always be on, and a value of AT&C2 sets CD to be always on, but to wink when there is

a change in the connection state.

7. Ensure that DTR is set to return to modem to command state on an ON-to-OFF transition

of DTR with AT&D2 A value of AT&D0 ignores DTR, a value of AT&D1 enters

online command state upon an ON-to-OFF transition of DTR.

8. Save the new settings in Profile 1 with AT&W1 and then set Profile 1 as the Default

profile with AT&Y1

9. To confirm your settings, do an AT&V. This will print out about 7 lines of text with all the

10. Confirm and that you are registered on the cellular network. AT+CSS? A reply of +CSS?

2,Z,99999 indicates that you are not registered. It may take up to 15 seconds or so after

power-up to register on the network. Once registered a typical response will be +CSS?:

1,A,4152 where 1 is the band class, 1=800 MHz, 2=1900 MHz, A-F is the band (Z

indicates not registered on network), 4152 is the SID, i.e. the cell tower ID, (99999

indicates not registered on network).

11. Create a Dial-Up Networking (DUN) connection using the modem that you created with

the active COM port, i.e. COM1 in Network and Dial-up Connections. Configure it to

115,200 bps and set Security to Typical.

12. Start a DUN session by double clicking on the DUN icon that was created.

13. Set the username and password as defined in the Appendix for your carrier.

14. Enter the phone number as #777 with no area code and click on Dial.

15. The modem will dial out and attempt to connect.

16. If the configured baud rate for the modem, the COM port, the modem and the DUN do

not match, the DUN will not be able to talk to the modem properly and you will get a

hardware error message. Otherwise the DUN will contact the cellular network and

authenticate the user on the network.

17. Once connected you will be able to browse the Internet through the DUN session. To

confirm this, disable any other network connection you may have running.

2.3 Fast-Track: Activating your Modem

1. Connect the modem to an active COM port on a PC with an RS-232 9 pin straight

through cable.

2. Attach the antenna and power connector.

3. Connect with a Hyper-Terminal session set to 115,200, 8 Bits, No Parity, 1 Stop Bit, and

Hardware Flow Control enabled.

4. Confirm contact with the modem with AT+GSN this prints out the ESN of the modem i.e.

(+GSN: 45262036). If you get an Error or no communication, go to the section on

Communicating with the Modem.

5. Verify that you have good signal strength, AT+CSQ?. A typical reply is +CSQ? 19,99.The

signal strength ranges from 0 to 31, the higher the number the better the signal.

6. Confirm and that you are registered on the cellular network. AT+CSS? A reply of +CSS?

2,Z,99999 indicates that you are not registered. It may take up to 15 seconds or so after

power-up to register on the network. Once registered a typical response will be +CSS?:

1,A,4152 where 1 is the band class, 1=800 MHz, 2=1900 MHz, A-F is the band (Z

indicates not registered on network), 4152 is the SID, i.e. the cell tower ID, (99999

indicates not registered on network).

7. Perform the activation instructions specific to your carrier as indicated in the Appendix.

I.E. For Verizon, OTASP can be initiated with an AT command, AT+CDV*22899. Wait 4

minutes and then test that it worked.

8. Confirm that the modem is activated, by performing a voice call to your cell phone,

AT+CDV<Cell Phone Number> (Use no spaces or angle brackets). Your cell phone

should ring and display the phone number of the modem.
