2 Deployment Notes Overview This document describes considerations for implementing and deploying an mobile application that uses for communications. s implementation of gives customers the same capabilities as they have today using RS232 serial communications for sequential, point-to-point mobile computer communications. The implementation involves changes to several components. You will need to upgrade each of these to create and deploy an application using. -Designer version 3.16 version Client version Designer -Designer has been modified to provide an option to set up communications for your mobile worker application. -Designer has also been modified to allow you to download your project to your mobile computers over. To do this, needs to be installed on the same system as your -Designer. -Designer does not use ; it only uses the driver. However, this means that every time you use - Designer to download a project, -Designer temporarily disables. -Designer re-enables when the download is completed. has been modified to install a new service that handles the communications and the control. In order for to operate properly, needs to be installed on the same system as your. does not use ; it only uses the driver. However, this means that only or may be used at any given time on that system. When is running, it disables. When you quit, it re-enables before terminating. -Client Like, the -Client relies on already being installed on the WinCE terminal. -Client does not use ; it only uses the client driver. However, this means that only -Client or may be used at any given time on a terminal. When -Client is running, it disables. When you quit -Client, it re-enables before terminating.

3 Deployment Notes rchitecture involves serial communications. This means that communications are point-topoint and that each terminal communicates with sequentially, one terminal at a time. single will support up to 16 cradle slots. Each cradle slot may be used to service more than one terminal. Figures 1-4 below show the architecture and possible deployment configurations using. In multiple terminal deployments, single slot and 4- slot cradles may be used in any combination with hubs to give up to 16 terminal slots. Sends command to to open or close Switch.

7 Deployment Notes pplication Programming Considerations Upgrade Existing pplications To use functionality, you need -Designer V3.16 and an V3 project. If your existing application is a V2 project, follow the normal Import from V2 capability provided by -Designer V3 to convert your project from a V2 project to a V3 project. Use the Migrate Wizard, if applicable, to forward migrate your V2 DOS projects to V3 projects. Once you have upgraded your application, modify your RS232 serial communications to communications. See Communications Parameters below for the proper settings. Multiple Terminals If you intend to have multiple terminals uploading and downloading data to and from in an unattended mode, create your application such that each terminal tries periodically, and repeatedly, to get the line to communicate with. When its turn arrives, have the terminal establish a connection and perform the relevant uploads and downloads. For multiple terminals to communicate unattended with, each terminal must be assigned a unique terminal ID. When a terminal has established a session and is performing its uploads and downloads with, any other terminal trying to establish a session will receive a busy status from. If you have many terminals all trying constantly to establish a session, could be become very busy sending busy status indications. This could take s attention away from the first terminal and result in a performance impact on the first terminal s upload or download communications. Therefore, recommends staggered attempts by multiple terminals to establish sessions and retries. To stagger the retry periods for establishing sessions with, consider using the terminal s unique ID as a variable in calculating the delay time. For example, choose a unit of time, of, say, 500 msec. Then, for a terminal with ID=3 create a delay of 0.5 sec x 3 = 1.5 sec. before retrying. This randomization will help to minimize the collisions between multiple terminals trying to establish a communications session with. January 2006 Page 7

8 Deployment Notes Requirements -Designer V3 version 3.16 or greater Windows XP or Windows or greater installed -Designer Device Plug-ins v3.16 or greater o Compatibility Note: -Designer v3.16 is fully compatible with previous versions of the DDPs. Non- DDPs will disable the functionality. version or greater Windows XP or Windows or greater installed uses UDP sockets to communicate. Therefore, a TCP/IP stack must be installed -Client version 3.13 or greater 3.8 installed on the mobile computer o Note: WM2005 requires 4.0 Mobile Computer or cradle with port Supported Devices -Designer Device Plug-ins (DDPs) and -Clients have been created for the following devices: Symbol: MC1000, MC50, MC3000, MC3070, MC9000, MC9010, MC9050, MC9060, MC9062 Intermec: CN2, CN2, CK30, CK30B, CK30C, CK310G, 740, 750, 751G 760 Datalogic: Jet, Kyman-Net, Viper-Net January 2006 Page 8

To use, select it in the System Menu in the communication mode combo object. January 2006 Page 9

10 Deployment Notes Limitations -Designer Only one port is supported at a time, for one device at a time. -Designer temporarily disables when it is sending a project to a device. -Designer re-enables when the Project Send is complete. It is not possible to use the from 2 instances of on the same platform. One allows communicating with all the terminals (each in turn) connected via the thru a single slot or 4-slot cradle. hub may also be included in the configuration. disables when running. re-enables when is terminated. -Client If the option is selected in the System Menu, -Client monopolizes the port. To use the port for another software package, close the -Client. Miscellaneous Technical Information.EXE object new object has been created and is used by both -Designer and. It performs the following functionalities: Detect the insertion of a device for an already open COM port. Detection of a plugged device(s) when the COM port is opened. Opening and control of the COM port on the Host side including the termination of if present. Process incoming messages from the terminal in UDP WN (single port) mode or UDP LN (dual port) mode with message parsing. Installing the service. The service is installed automatically with the installation of -Designer v3.16 and v The installation procedure verifies if it s a Windows 2000 or Windows XP platform. warning is displayed if the driver is not present. If a previous version of the service is already installed, it is deinstalled before installing the new one. New functionalities: Mcl-link setup: added in the Combo-box Stop the service if it s running Start the service using the standard UDPLN, 5001, 5099, Subnet 1 parameters (display a message in case of error) = Base port (5000) + ((Subnet 1)*256) = Base port (5000) + ((Subnet 1)*256) + 99 When is stopped, the service is also stopped. listens to the Localhost 5099 port and speaks to the Localhost 5001 January 2006 Page 10
