WireLess TelNet "WTN52" is a Telnet client for Symbol Technologies series 3000 PDT (PDT 3940, 3140, 3840, 1040) and 6000 PDT (PDT 6140, 6840) terminals.
WTN52 support various terminal emulations : 5251-11, and 3270.
WTN52 is "fully-configurable" program by text configuration files, that allows local language customization, and special adaptation to various Telnet implementations, and expected terminal behaviors.
Configuration file is composed of "sections", to adapt :
WTN52 is shipped with standard configuration files that responds to the most popular configurations.
WTN52 includes a "message file" that contains all the messages shown by the PDT WT application to the user. You can translate or modify the messages to adapt or localize the emulation. The message file to be used by WTN52 is choose by an option in the configuration file. (WTN52 program has already some message files in several languages).
The download process of the "message file" is the same as the "configuration file".
WTN52 installation is done in following steps :
Telnet application may require to modify standard WT parameters in configuration files. Those files may be downloaded into the terminal in several ways :
In static configuration, the needed files are included and downloaded with the WTN52 program at once into the PDT NVM. If "Bios Boot" is done, terminal recalls the NVM parameters.
This option needs to rebuild a customized version of "WTN52xx.HEX" and needs to install WTN52 Build Kit (that includes some Symbol SDK utilities).
If you choose static configuration files, be sure to keep the special WTN52xx.HEX built version, if you need to download other terminals. If you modify some parameters you need to rebuild WTN52xx.HEX and download all the PDTs.
Using dynamic configuration, needs to download the configuration files to the PDT from a Host computer, at any time, and can be done in several ways :
If you choose dynamic configuration files, those files will be downloaded once. Dynamic download replaces the configuration files into the "Flash Memory" and they aren't lost when "Bios Boot" is done.
Modify the "_WTn52.cfg"
(SEE CHAPTER V)file under the folder Wtn\52\Nvm\Cfg with a
text editor.
You may modify the "message file" (_Msg52xx.cfg) or create a new
file (SEE CHAPTER VI).
Rebuild the cfg.zip file with WinZip (cfg.zip includes all the configuration files).
Rebuild the WTn52xx.hex file by "usrcfg" Symbol technologies utility.
To load WTn52 in a Symbol Technologies series 3000 PDT, it is necessary to download to the PDT NVM two “DOT.HEX” files :
Using NvmHex or RsLink utilities (see APPENDIX D) . This utilities sends the ".HEX" file to the PDT by writing the Non Volatile Memory.
You may load other configuration files (_WTn52.Cfg, _Msg52XX.Cfg ) by RsLink utility, or use those included into standard WTn52 NVM.
Network parameters needs to be configured into the Host and Client systems.
PDT network parameters may be configured by CFG24 or CFG11 utility, called from
WTN52 main menu.
Ask to your Network Administrator for :
See CHAPTER 2 NETWORK CONFIGURATION and APPENDIX E for CFG24 or CFG11 Utilities.
If you choose dynamic configuration files, you need to download those files to the PDT. Those files will be downloaded once. Dynamic download replaces the configuration files into the "Flash Memory" and they aren't lost when "Bios Boot" is done.
Serial download needs to install RSLINK utility into a Windows-based PC with Windows 95, 98, Me, NT4 or 2000.
After a "Bios Boot" the terminal in the "Boot Menu" asks for whished download. Choose "F1 By RsLink" option.
See APPENDIX C DOWNLOADING CONFIGURATION FILE and follow the instructions for RSLINK download.
WireLess TelNet Download (WTDnl) is a TCP/IP server utility that allows to download configuration files from a PC to the PDT. PC Network download needs to install WTNDnl utility into a Windows-based PC with Windows 95, 98, Me, NT4 or 2000.
The PC must be connected to the same network that uses the PDTs. You need to enter the PC IP address that is running the WTDnl server into the PDT.
After a "Bios Boot" the terminal in the "Boot Menu" asks for whished download. Choose "F2 By Radio" option and supply the IP address.
See APPENDIX C DOWNLOADING CONFIGURATION FILE and follow the instructions for WTDnl download.
The user message file contains all the messages the PDT displays. You can translate or modify the contents of the message file. The message file used by the terminal is set into the configuration file.
Several message files are stored into the PDT NVM (CFG zipped folder) and may be selected at run time by the configuration file.
The user message file (_Msg52XX.cfg) is automatically downloaded with the configuration file if you use the RsLink download option.
See CHAPTER 6 MESSAGE FILE for the syntax and features of this file.
Warning : The user message file uses the font indicated into the configuration file to display messages.
Some messages (those displayed before configuration download) are unique and should not be translated.
When WTn52 boots, the following sequence is done :
1) Driver installation test. Check if the S24 drivers are into the flash memory. If not, send the WS24_XXX.HEX or WS11_XXX.HEX file to install them (See Appendix D).
2) Recall parameters from NVM to flash, if the recall option is used ("Recall.Yes" file in CFG.ZIP). Overrides the downloaded files and restore NVM defaults (usually with static files).
3) CFG24 or CFG11 utility call, to view or modify network parameters.
4) WTn52 Application :
4.1) WTn52 Boot Menu.
Serial or Network download option (only at boot time).
4.2) WTn52 Main Menu.
If a dynamic download is done, the new files are stored into the Flash memory to recall them into the next boot (usually with "Recall.No").
You may call CFG24 or CFG11 utility from WTn52 application Main Menu later to modify network parameters.
You may exit to DOS with F10 ([FUNC]+[0]) function from Main Menu to perform DIAG24 or DIAG11 "site survey" utility.
