Some of the cloud-requiring devices can be cloudcut/flashed, but that is by necessity, a moving target very similar to the ongoing ublock/youtube action. For the rest, yes, a standardized communication port would be nice, but oh god please make it USB and not rs-232. The genderfuckery and literal crossed wires make me cry, and it's going into a USB adapter anyway.

Hi Foone,

I recently came into possession of a PERCON Falcon 320 handheld DOS terminal/barcode reader thing from 1998. It seems to complain about being unable to connect to a server, as well as some kind of firmware corruption, every time I reset it, and it seems it uses a nonstandard (with added power pins) 10-pin ethernet-shaped RS232 connector for interfacing. The configuration software seems to have downloads hosted only on very sketchy shareware sites (it doesn’t strike me as likely that Datalogic’s current software supports it, since the product isn’t listed on their website, only the newer Falcon X3). I can’t find any of the required cable on eBay, so it’s likely I’ll have to open it up and solder/otherwise jury rig some direct connection to something my computer can connect to via an RS232-usb adapter or something. Do you or anyone you know have experience flashing ROM/directly serially interfacing with stuff like this? The advanced user guide I can find by googling doesn’t give an exact spec on serial comms, just how to use the default config software and a pinout for the serial port, as well as how to use the DOS XFER command.

Sorry, not really. I usually have to find manuals or those rare adapter cables to get this stuff to work.

Good luck!

If you do not have the serial cable bundled with the Cybiko, you should know that they’re practically impossible to find. If do not mind making a small after-market modification to the Cybiko, you will need to do some soldering work to add some wires, which we will later attach to an RS232 port. This is necessary because Cybiko used a proprietary connector and as far as I can tell no other device used this connector, and therefore the cables are becoming quite rare.

In the Beginning: The History and Evolution of Device Servers

Lantronix PremierWave EN dual band WiFi device server

In the beginning (well the 1980s), there were terminal servers. And they were good. These devices allowed for dozens of ‘dumb’ terminals to be connected to a mainframe or minicomputer over a single wired Ethernet connection. They were widely deployed at banks, automotive dealerships and insurance companies - anywhere a concentration of computer users was to be found. One of the main benefits was not having to run yet another cable all the way from the main computer to the new terminal location. As these terminal servers advanced, they allowed for another level of authentication to be implemented, via local username and password. Savvy administrators started finding ways to also connect printers to these servers and ultimately, terminal server designers added direct support for print queuing. This was a substantial timesaver, as now the printer could be placed near the user without a dedicated drop. Since some printers were installed remotely without associated terminals, it was a natural extension to create a terminal server dedicated to attaching printers to the network. With this, the print server was born.

With the explosive growth of microcontrollers in products, a plethora of equipment that had serial connectivity began to emerge. Asynchronous serial was a well-established means of communicating with a computer and with the addition of a UART and line driver, it became easy for a designer to allow a way to interface with their new products. The problem then was that serial only worked well over 50-100 feet, depending on data rate. Someone came up with the idea of using a terminal server to connect these products (alarm panels, industrial equipment, medical devices, etc.) to the network. Most of the available terminal servers had high port counts (16, 32) so it was rather expensive to use a terminal server on the shop floor to hook one or two machines to the network. Lantronix solved this problem by creating 1-, 2-, and 4-port ‘serial servers’ as they were first branded, later coining the term ‘device servers’.

Initially, device servers were external ‘box’ products consisting of a small plastic or metal enclosure, which contained the serial-to-Ethernet conversion circuitry, regulated power supply, led indicators, Ethernet connector (RJ45) and the requisite RS232 connectors. Over the years, these boxes have shrunk in size and added additional interface types, including RS422 and RS485. Originally, the software enabled basic serial-to-Ethernet conversion (often called ‘tunneling’). As technology advanced, the firmware became much more configurable and for some applications, became protocol-aware. This was important because if data was not properly packed into a TCP (network) packet, it could become fragmented when arriving at the other end of the connection. This fragmentation could cause timeouts and other bad behavior from products and software used to having a direct connection.

In the late 1990s, web servers were added to device servers, giving them a new way of being configured and for data presentation. At this time, OEM manufacturers inquired about embedding device server functionality onto their main boards. Small products specifically designed for being embedded were created. These dispensed with the power supply regulation and serial interface circuitry. They were ideal for integrating to a main board, requiring only logic level power and signals. True to device server technology, they handled all of the tasks associated with getting a machine on to the network. It made networking easy for an OEM. In 2002, Lantronix changed the face of embedded device servers when they came out with the ultra-miniature XPort. This was a complete serial-to-Ethernet device with web server in a standard sized RJ45 jack (about the size of two sugar cubes). Millions of these devices have been deployed worldwide.

The next logical step was to branch out to additional transport types including wireless 802.11. Both embedded and external device servers have been produced utilizing the ever improving 802.11 standards. 802.15.4 and Zigbee have also benefited from the creation of embedded modules.

While many additional customer interface standards have been created, asynchronous serial is still the most common way device servers are connected to equipment, both in embedded and external applications. More recently, SPI has become interesting for high-speed transfers from an OEM main board to an embedded device server, as well as 802.3 wired Ethernet (“bridging” to 802.11 wireless).

Where are device servers headed? Physical size reduction is always foremost on the list. Also having faster ways to interface to an embedded device (i.e. SPI, USB, etc) to improve overall bandwidth. It has been imperative to add additional compute power and memory resources for tackling increasingly complex encryption and authentication methods. This extra ‘horsepower’ has obviated the need for a main processor in some embedded applications. It’s funny to think that just eight years ago, a device server might be able to execute 30 million instructions per second. Now it is upwards of 400 million! Additional I/O capabilities allow a wider variety of sensors and other peripherals to be attached to a device server. And of course, keeping up with the latest standards in wired and wireless communications is a must. Device servers have come a long way, but the goal remains the same: Handle all communication tasks from A to Z, whether wired or wireless, and provide a very easy-to-implement solution that keeps the customer focused on their core business and gives them a huge time-to-market advantage.

HDMI switch and multi-viewer switcher. Should I buy a more functional device right away?

You must connect multiple video sources to a TV with only one HDMI input. Switching the HDMI cable is inconvenient and causes wear and tear on the TV connector and its repair. Instead, your best choice is to buy an HDMI switcher. This device usually has several HDMI inputs and one HDMI output. You can switch sources using the buttons on the front panel or with an IR remote control. Some switchers have an RS-232 port for connecting external control systems.

When looking for an HDMI switch in stores, you may find a more advanced device, the multi-switch, which costs a bit more. What is it? Is it a good buy? Let's find out.

HDMI switch. General view

What is an HDMI switch, and how does it work, using the INRIKS SW4031 (analog is Lenkeng LKV301-V2.0) as an example? The device has 3 HDMI inputs for connecting video sources (laptop, TV set-top box, video recorder, etc.) and 1 HDMI output for connecting a monitor / TV / projector. The maximum resolution is 4k@60fps.

The device is shipped in a cardboard box. This is the usual packaging of devices for the professional consumer. Mass-market products are often packaged in boxes with colorful prints.

The Switcher has a compact size. The bottom of the package contains the IR remote control, a 5 V power adapter, and instructions.

All connectors are located on one side. This feature simplifies the wiring organization. In addition to the HDMI ports and the input for the 5V power adapter, there is an RS232 port. This is another attribute of professional orientation. The device can be connected to various control systems. For example, to control audio/video complex with one console, touch screen, or for automation (running some scenarios). This extensive theme is better explored in more detail in a separate article.

The status indicators (on/off, active input) and the input switching button are on the front side.

The remote control has a minimum button count.

The case is made from thick metal and feels very monolithic in the hands. The connectors fit very well. The gaps are minimal.

The soldering of elements and connectors is neat.

HDMI switcher. Performance testing

According to the diagram, we connected three laptops and one monitor to the switch.

We found a delay of several seconds when turning on the first input. The same delay is also present when connecting the laptop to the TV directly. It is explained by the two devices matching, which takes time. The picture quality is excellent.

We see the same delay when we switch to the second and third inputs. When switching back to the first input, we see the same delay again, i.e., the matching process happens repeatedly.

This switching is common to all low-cost HDMI switchers. If the long switching time is unacceptable, you should look for a device with Seamless Switching. This function is necessary to switch between cameras during live broadcasts on the Internet.

You can select the desired input or scroll through all video sources individually with the remote control.

The manual contains a port setting description and switching commands for RS232 control:

HDMI multi-viewer switcher. General view

What is a multi-viewer switcher, and how does it work (using INRIKS SW4041MS (analog is Lenkeng LKV401MS) as an example)?

This device has four HDMI inputs for connecting various video sources (TV set-top box, DVR, laptop, etc.) and one HDMI output for connecting a TV. The maximum resolution is 1080p@60fps.

The SW4041MS multi-switch comes in a similar cardboard box as the regular switch. The package contains the multi-switch, a 12V power adapter, a removable surface mount, and instructions.

Unlike the usual switch, the SW4041MS has HDMI and power cable connectors on both sides. Four HDMI inputs are on the rear side. One HDMI and a DC 12V power input are on the front side. The control buttons and the IR receiver are also on the front side.

Brackets for attaching the multi-switch to different surfaces are included. This is a big plus to the installation possibilities.

The remote control has a large number of buttons for flexible device control.

Multiswitch's housing is made from quality metal. The soldering of elements and connectors is neat.

But we do have a small comment about the location of the capacitors. They clearly tried to fit into a small space. Although this element feature does not affect the performance. We don't have any complaints about other elements.

HDMI multi-viewer switcher. Performance testing

According to the diagram, we connected four video sources and one monitor to the multi-switch.

According to the manual, in addition to the classic switcher function, the device under test has a multi-viewer function - the simultaneous display of one, two, or four video sources on the screen.

We switched inputs and saw instantaneous switching without image crashes or pauses in full-screen mode (classic HDMI switcher). This surprised us. Usually, devices with this ability cost many times more.

However, we quickly found the "price" of a quick switch. We have decided that the video bit rate is reduced. It is a slight distortion of colors. The multi-switch slightly distorts the image. When displaying standard video, the distortion is almost invisible. But if you display the laptop desktop, the distortion becomes more noticeable. For example, dividing lines in some programs, which were barely detectable in the original image, have disappeared.

When testing the multiscreen function, we concluded that you can actually use «Full-screen mode» and «Quad mode – 1».

In other modes, the multi-switch distorts the image.

In addition, we want to draw your attention to sound. In multi-mode, you can separately specify from which source the sound is output. This is very convenient.

Conclusions.

The choice is simple.

Case One.

You want to connect multiple video sources to one TV (projector) and switch between them. It would be best to choose a standard HDMI switcher (e.g., SW4031) without additional functions.

Case Two.

Your task is to display multiple video sources simultaneously without high image quality requirements. For example, to view multiple video recorders at the same time. You can buy a cheap INRIKS SW4041MS multi-viewer switcher. But this device distorts a video image's color and aspect ratio.

I've also seen these on custom AV installations where a single large cable is used to run a number of different signals a decent distance, and then breaks out into a cable like this on either end. I've personally installed some that use a half inch thick cable terminating on both ends with a DB25 connector, and a breakout cable that has two RCA composite video, RCA mono audio, RJ45 PTZ camera control, RS232 terminating in a DB9. Here are some of the cable diagrams for those cables:

Cable T511 was 50 feet of 1/2" thick cable. It was a beast to run, and we'd usually have at least 2 of them.

Here's another cable diagram for another of the cables that came in the kit:

For those interested in learning more, this is from the Tandberg Educator MXP classroom video conferencing system. https://www.clarybusinessmachines.com/products/files/tandberg/tandberg_educator_mxp_user_manual.pdf

any idea what this cable is?

looks like 9-pin vga on one side then breaks out into 7 wires labeled composite? on the composite side, one red wire is labeled "Composite Sync Output", one blue is labeled "C/V Sync Output", one green is labeled "Y/H Sync Output", and the black wire is labeled "Composite Video Output". the cable itself has a tag that says "cable from splitter to monitor"

That's probably designed for some specialist video card that generates output for professional video production. That's why it's got separate syncs, because that's often needed to properly genlock all the stages.

No idea what specific card it is, or what device you'd plug it in, but this is the kind of cable that gets custom made for one specific card type and the next card will use a completely different cable, so both the cable and the card are useless when they get separated, as they inevitably do :(

Benefits of Masterclock

GPS radio wires are for the most part resistant to climate and intended for mounting outside, frequently on a rooftop top. The cajole link utilized masterclock price in dubai UAE relies upon the increase of the recieving wire and the transmission misfortune related with the link type. A common 40dB recieving wire can use in overabundance of 100m low-misfortune LMR400 or identical link. Lower quality, higher misfortune, link, for example, RG58, will have a lot more limited most extreme link length.

Flood silencer or security gadgets ought to be introduced where GPS radio wires are found outside. These safeguard costly hardware associated with the recieving wire from potential lightning strikes and other electrical floods.

For extremely lengthy link runs, a speaker can be utilized lift GPS signals. A GPS enhancer is a little gadget that sits in-line on the cajole link between the expert clock and radio wire. It is fueled from the expert clock, requiring no different power supply. Whenever required, various enhancers can be fitted at stretches along the link to additional lift signals.

The Organization Time Convention (NTP) is a standard Web convention for circulating exact opportunity to PCs over an organization. NTP is a various leveled convention. At the highest point of the order is a Layer 1 deadbeat that gets exact time from an equipment reference clock, like GPS. Equipment reference timekeepers are considered to be Layer 0. The Layer level decides the separation from the reference clock. For example, layer 7 will be 7 levels from the reference clock. Because of organization latencies and timing overheads, for the most part, the further a client is from a reference clock, the less precise the client time is. Ace timekeepers depend on NTP to synchronize network joined gadgets.

GPS clock frameworks are generally furnished with IRIG-B time code yields. IRIG is the US military Between range instrumentation bunch. IRIG time codes portray standard arrangements for time move. IRIG_B is the likely the most widely recognized IRIG time code. It moves time spans at 1 casing each second with a 100hz piece rate.

Ace tickers might give various advanced and simple time code yields. The most widely recognized time code yields are IRIG-B, 10MHz, 1pps and ASCII yields.

Research center and test gear frequently utilize a 10MHz recurrence reference for synchronization. This is by and large given by utilizing GPS timing signs to teach an OCXO oscillator. The result from the oscillator is then given on a BNC type RF connector.

One heartbeat each second (1PPS) yields give a brief term beat yield that is definitively adjusted to the beginning of each second. A 1PPS yield is frequently given at 5V (TTL) voltage levels and gave on a RF type connector.

ASCII information move is directed over a sequential connection point, ordinarily RS232. Nonetheless, other sequential point of interaction guidelines, for example, RS422 and RS485 are normal. Numerous GPS clock frameworks give time and date data at intermittent stretches through a sequential point of interaction. Gear with sequential points of interaction can then utilize the time code for time synchronization. There is no conclusive norm for ASCII time move. For the most part, the arrangement of the time not entirely settled by the maker of the gadget alongside the sequential port setup.
