Re: Changing the time on a siemens optipoint 500

The only thing I can suggest is if you phone has a battery remove it and remove the phone from the telephone line for a few hours this may make the phone lose its memory and prompt you to set everything up,such as the time on startup

The OptiPoint phones take their time from the system not the phone itself. Log in to your system using Manager C or by using admin access on the main system phone and set the time there. Rich Foleher Siemens Support

Free SMS software developer

Like Gnokii, Gammu is a free and open source command line tool that can be used to send and receive SMS messages from a computer via a mobile phone or GSM modem. Gammu was started based on Gnokii's experience but it evolves independently. Besides sending and receiving SMS messages, Gammu can be used to perform many different tasks such as reading and writing entries of the phone book and calendar, handling logos, loading ring tones, managing bookmarks, changing WAP settings, making data calls, etc.
Gammu supports mobile phones that can work in AT command mode. Like Gnokii, Gammu supports lots of Nokia mobile phones, even some of those that use Nokia's proprietary protocol instead of AT commands for communicating with a computer. A list of the mobile phones and GSM modems supported can be found on Gammu's web site.
If you are not an SMS software developer, you may want to use Wammu instead of the command-line Gammu. Wammu is a program developed with wxPython. It provides a good-looking and intuitive GUI, which is easier to use than Gammu. Some screenshots of Wammu can be found at here.
If you are an SMS software developer and want to write a program to send and receive SMS messages from a computer via a mobile phone or GSM modem, you may find Gammu useful. By making use of the functions of Gammu, you do not need to learn about AT commands in order to control the mobile phone or GSM modem. It is easy to write a script or program to drive the command-line Gammu in the background. Another choice is to use LibGammu, the back-end library that provides basic functions to Gammu.
In addition, you can find two pieces of software, Python-Gammu and Gammu+, on Gammu's web site. Python-Gammu is a Python module that allows software developers to get access to Gammu's functions in Python scripts. Gammu+ is a C++ version of Gammu. Gammu+ and Gammu are released under different licenses.

I have connected Lantronix UDS1100 Device with Siemens AZL Meters. But not able to get complete data on front end.

The UDS has the following LEDs, which help you diagnose problems.
Power LED (green)
Ethernet 10/100 Link (yellow = 10 Mb/green = 100 Mb)
Ethernet Half/Full Duplex Activity (yellow = Half Duplex/green = Full Duplex)
Diagnostic (red)
Status (green)
Simultaneously lit Diagnostic (red) and Status (green) LEDs mean something is
wrong. If the Diagnostic LED is lit or blinking, count the number of times the Status
LED blinks between its pauses. The following table explains the LED functions:

Try this one:

>on ur WIFI networks, click "other..."
>then manually type in ur network name (if its set to default, it should be 2WIRE and the last 3 digits of ur SN. It is case sensitive so type the name exactly how it looks like.)
>make sure that the setting is set to WEP
>on the password box, enter a dollar sign/$ first and then the 10 digit code under ur 2wire

Address keeps changing

When you say the address changes, is this dongle device connected to a parrallel adapter running on your computer network?

If so you could try going into the network settings of your device and forcing that IP address that your on to stay on that device rather than having the router assigning it to you.

The other way is to leave the computer on. That should keep the same IP address as well.

External Antenna

First, try changing the channel your access point (AP) is using. Maybe there is some interference with another AP or with an electronic appliance such as a wireless phone. Try all available channel. While changing your channel number, make sure that the wi-fi power of your access point is set to the maximum available (100%).

Second, make sure that there is as less metal as possible around the AP, for example if the AP is sitting in a metal book case or on a metal shelf.

Third, some appartment buildings, expecially old ones, have very thick walls made of concrete or brick. This is a nightmare for wi-fi. Try bringing the AP to a more central point in your appartment, if possible (I know this may be complicated).

Cannot upload mail

I've had this problem before but it normally corrects itself and returns to normal. The only thing I would suggest is cleaning out all your cookies, temp files and then run a spyware program and clean everything out. Login and see if that helps. Good luck.
