This DataComm product is a transceiver module designed for 2km optical communication applications. The
design is compliant to IEEE802.3ba and 100G-CLR4 standard. The module converts 4 inputs channels
of 25Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for
100Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a
100Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data.

Usually, an RS232 - RS485 converter is the preferred way to establish multi-point networks when working with RS232 devices. This is a method for connecting multiple RS485 devices with each other over a two-wire network. However since only a true RS485 network can have addressable serial RS485 devices, the RS232 converter needs to be addressable either by software or by DIP switches when using it in this type of configuration.
RS232 to RS485 converters are regularly used in industrial and modern environments. The idea is that the RS485 converter can be used for multi-drop channels, meaning that you, for example, can combine multiple RS485 devices to one computer. Up to 32 devices can be connected in one network to communicate on a single pair of wires (plus a ground wire), and the number can even be increased by using RS485 repeaters. This type of communication is called half-duplex communication. Most feature RS485 converters can give in this manner of up to 4000 feet (1200 meters). The RS485 converter is also fairly immune to noise which is one more reason why it is favored in industrial situations.
Tracking police man using rf proximity cardAlbert Jose
Security is the important cause in the modern world. Now a day so many schemes have
announced by the banks which very attractive and the people are saving money in banks. At this
point protecting the banks is the main duty of police. Hence police are appointed securities to the
banks and make them to patrol during nights. . They have to go to every banks and streets and
sign the books kept in their places .But some police people forgot their duty and will sleep in a
vacant place and in the morning they get up and in a hurry go to these banks and put a fake time
and date and the signature .To avoid this and to provide more security our proposed system is
giving solution for tracking police man using RF proximity card. A RF proximity card reader with a
microcontroller will be designed and will be placed in every bank. During the patrol time, when a
police man swipe the card it will read the card number and will store it with date and time. The
data can be retrieved by connecting the machine to PC and giving appropriate commands.
Tracking police man using RF proximity card embedded system project explains about
new method for bank officials for checking their security of the bank by implementing accurate
method to control police officials. In present scenario banks are playing important role in providing
security for people for saving their money, gold..Etc. So banks are taking serious steps to
maintain security like hiring police officials at night time for patrolling banks, but there are chances
in irregularity of police officials so this method will provide card system for every police official
who should scratch his card. Data and time is stored inside system which can connect to
computer and analyze details of his attendance

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

2. The benchmark for flexibility.
Laser scanners of the BCL 20 series –
as variable as your requirements demand.
Whether as a single-line scanner for high-density codes, for example, in analysis
automation, with raster optics for reading trays in intra-logistics applications or
for inspecting industrial or printed products: the compact bar code readers of
the BCL 20 series convince with their high level of flexibility and handling reliabili-
ty in all areas.
The broad selection of optics also allows the scanners to be used in difficult
installation situations and in a wide range of applications, both in networks as
well as a standalone solution. Furthermore, the BCL 20 series convinces with its
outstanding reading performance through the automatic adaptation of the
receiver unit to the reading task on each scan. For an extended reading field,
such as that of a bar code reader with focusing function, the new BCL 20 S B is
availabe for higher resolution codes.
By means of simple online commands it is possible to set the reading task
without knowledge of the code. The PC-based BCL-Config tool, which is avail-
able for all Leuze bar code readers, is used to access the full function range.
Simple online commands make it possible to set the reading task without know-
ledge of codes. The BCL Config tool, which can be used for the entire function
range, is available for all bar code readers from Leuze electronic Connectivity.
Connection to industrial or Ethernet-based networks is now done directly via our
MA 200i modular interfacing units.

4. Universally usable – fast integration –
simple to operate.
The advantages of the bar code reader series BCL 20.
Various optics models: Different models with front or lateral beam exit ena-
ble optimum use of the installation space. Depending on the code alignment,
single-line or raster scanners offer optimised reading capacity
High, constant scanning rate up to 1000 scans/s: Considerable increase in
the reading reliability through multiple decoding of the read codes, even during
fast processes
Large depth of field and wide opening angle: High reading capacity with codes
having line thicknesses as narrow as 150 μm facilitates front or lateral reading
on your goods
Integrated multiNet: Up to 31 scanners can be networked in Leuze electronic's
own scanner network with minimal installation effort and, if desired, integrated
via gateways to the fieldbus level or directly to the host
Simple operation: With the aid of online commands such as AutoConfig, the
scanner can be set optimally, even without knowledge of the code
Easy configuration: The PC-based BCL-Config operating software for all Leuze
bar code readers simplifies adjustments and direct communication with the
scanner through graphical configuration
Blue laser diodes with extended reading field without focus adjustment for
higher resolution codes and optimized optics for glossy and cylindrical objects.
