1. Overview 1.1. CS-CDPD The MP215 is a radio modem that supports CS-CDPD operation. CS-CDPD is a specification for doing CDPD communications over a circuit-switched cellular AMPS connection, and is described in detail in the CDPD Implementor Guideline Part 1024 published by the CDPD Forum (now the Wireless Data Forum). Like CDPD, CS-CDPD is a specialized service that must be available from a cellular carrier in order for modem operation to be possible.
MP215 Mobile Modem Installation, Configuration, and User’s Guide 1.3. MP215 Host Interface The MP215 is not completely backwards compatible with existing Sierra Wireless CDPD modems, as the nature of CS-CDPD operation makes this unfeasible. The major differences relate to behavior in response to AT-commands. Section 9 of this document describes how the host interface varies from the Sierra Wireless standard. 1.4.
2. MP215 Installation Instructions are provided here for installing the modem in a vehicle, connecting an antenna, connecting the vehicle power supply to the modem, and connecting the serial cable. 2.1. Installing the Modem in a Vehicle 1. Choose a convenient mounting location in the vehicle. 2. Mark the location of the mounting holes as appropriate for your installation. 3. Drill the holes. 4. Mount the unit using appropriate sized screws. 2.2.
MP215 Mobile Modem Installation, Configuration, and User’s Guide 2.5. Warranty Registration Product registration is important because it ensures that you will stay up to date on product upgrades and accessories and receive warranty service and technical support. Please be sure to register your modem by either sending in the Warranty card, using the Warranty registration feature of Watcher, or via our webpage. Sierra Wireless Inc.
3. External Interfaces This section describes the Serial Host Interface, the Power Supply Interface, Modem Status Indicator, Speaker Interface and RF Antenna Connector. Figure 3-1 MP215 (front view) 3.1. Host interface The MP215 connects to a host through a DB9 (female) connector using the RS-232-C serial interface standard with a maximum signaling rate of 57.6 kbps. The RS-232-C specification voltages for receiver and driver are shown in Figure 3-2. PN 2110036 Revision 1.

MP215 Mobile Modem NOTE Installation, Configuration, and User’s Guide The naming convention and signal flow is with respect to the modem not the PC (host) side. This means that TXD on the modem side is RXD on the Host Side and vice versa. The directions of the arrows indicate signal flow into the pin or signal flow out of the pin. For example, the pin labeled TXD has the signal flowing out of the pin and the arrow pointing away from the pin.

Modem Status Indicator The front panel of the MP215 has a single green LED indicator. The LED has several functions as outlined in Table 3-1 LED Indications.

Mating Connector Suggestions A suitable mating connector is: AMP P/N 5-554739-3. This connector requires a crimping tool to mate with a flat 8-way cable.
MP215 Mobile Modem Installation, Configuration, and User’s Guide If the cable loss between the modem and antenna is greater then 2 dB, it is acceptable to use a 3 dB gain antenna as the ERP will be within the 36 dBm +2/-4 dB limit. 2dB loss results when using approximately 15 feet or RG-58 co-axial cable. The antenna should be mounted well away from any objects that may ‘shield’ it from receiving signals. A roof top location is best.
4. Installing MP215 Firmware and Utility Software The MP215 will be shipped with diskettes or CD-ROMs containing MP215 firmware, as well as the Wireless Expert and Watcher utilities. The latest firmware release will be pre-loaded in the modem. As new releases of firmware become available, they can be downloaded from the Sierra Wireless website (www.sierrawireless.com), or can be shipped in diskette form on request. 4.1.
MP215 Mobile Modem Installation, Configuration, and User’s Guide 4.2. Installing Wireless Expert and Watcher Software To install Wireless Expert/Watcher software on your PC, load Disk 1 or the CDROM in your PC and run the setup.exe program. The install process is fully automated. Sierra Wireless Inc.
5. Configuring the MP215 With Wireless Expert For Windows and NT users, basic MP215 configuration can be done via the Wireless Expert utility. (Note that Wireless Expert does not permit configuration of auto-switching operational timers, or all S-registers.) Configuration of all other parameters must be done via AT-commands and requires the use of a terminal emulation program such as Hyperterm. Provisioning via AT-commands is detailed in Section 4. 5.1. Setup 1.
MP215 Mobile Modem Installation, Configuration, and User’s Guide 5.2. AMPS Provisioning The Modem is configured for AMPS operation, including NAM (cellular number) and CS-CDPD Dial Code (1-800 number), from the following screen: Programming the NAM (the MP215’s cellular number) • Click on ‘Setup’ beside the NAM window. The following screen will appear: • Enter the phone number and home system ID, as provided by your cellular carrier, and click OK. Sierra Wireless, Inc.
MP215 Mobile Modem Installation, Configuration, and User’s Guide 5.3. Programming the Dial Code Click on setup beside the Dial Code window. A window similar to the one above will appear. Enter in the 1800 number and system ID as provided by your CS-CDPD service provider, and click OK. 5.4.
MP215 Mobile Modem Installation, Configuration, and User’s Guide DNS Configuration Wireless Expert permits you to automatically program the DNS address into the Windows Dial-up Networking configuration via the screen shown below. Simply click on the Change button and enter the IP address of your CDPD service provider’s DNS into the window that appears. Sierra Wireless, Inc.
6. Configuring the MP215 via AT Commands 6.1. Configuring the MP215 for CSC mode To configure the MP215 for AMPS operation, the modem must first be in CS-CDPD mode: AT+WS181=1 Places the MP215 into CS-CDPD mode Programming the NAM It is possible to program up to two NAM’s on the MP215.

Up to 10 different SPNI’s permitted. AT+WPSPNI? (optional) Confirm value of SPNI 6.3.
MP215 Mobile Modem Max value: Installation, Configuration, and User’s Guide Syntax: AT+WS250= Mode: AUTO Default: 300 seconds (5 min) 3600 seconds (1 hour) Maxcdpdscan Timer The Maxcdpdscan Timer defines how long to allow the modem to search for CDPD channels during an AUTO mode check. If CDPD service is not found within this time interval, the driver switches back to CS CDPD mode.

7. Operating the MP215 via Watcher The Watcher utility will permit the user to select the operational mode of the MP215. Note that unlike versions of Watcher for other Sierra Wireless modems, no further configuration of the MP215 can be performed. However Watcher also permits the user to monitor modem status, RF channel and signal strength (note signal strength is not available in CS-CDPD mode). 7.1. MP215 Operating Modes The MP215 can be run in one of four modes.
MP215 Mobile Modem Installation, Configuration, and User’s Guide Where Automatic Selection is Auto Mode, Circuit Switch Network is CS-CDPD mode, and Packet Network is CDPD mode. Sierra Wireless, Inc.
8. Operating the MP215 via AT Commands The MP215 can be programmed to operate in one of its four modes, configured via Register WS181, as follows: 1) CDPD Mode (WS181=0). This mode provides regular CDPD service 2) CS-CDPD (WS181=1) This mode provides CS-CDPD service, i.e. CDPD protocol over a conventional AMPS call. 3) CS-CDPD, No Answer (WS181=5) This mode provides CS-CDPD service but does not answer incoming calls (autoanswer disabled).

9. Host Interface 9.1. General Description The MP215 supports both a SLIP and AT-command interface. For a complete list of AT commands, the user should reference the Sierra Wireless Modem User Guide and the AT-Command Extension R2.5.2 reference guide, which describe the AT and extended AT commands that the MP200 family of products support.
MP215 Mobile Modem Installation, Configuration, and User’s Guide However, once the host DTE port enters a SLIP session or during the execution of the AT+WPREG command, normal operations will resume. In particular, if autoregistration is selected, the MP215 will perform the necessary operations to register the NEI with the network according the mode of operation selected by the +WS181 register.
MP215 Mobile Modem Installation, Configuration, and User’s Guide Legend: • Command The AT command • WS181 The required state of WS181 register (defines the operational mode). If blank, it means don’t care or not applicable. Otherwise an ERROR response will result if WS181 is not in the specified state. • Notes, Exception Special notes, including how the command executes. “Not supported” means the command will return an ERROR response.
