“Spooky apparition seen in Rochester cemetery, Medway,” says Matt McMillan, who has optimistically captioned his photo ‘Ghost of a Squirrel’.

“Being a suitably dark and stormy night, the lights were occasionally flickering. The lighting system is a shambles, working intermittently and highly prone to problems thanks to its unpredictable motion-activated sensors. The lights were doing odd things. Clicking and burring - fluorescent tubes were sputtering and clacking.”

“In 2011 I went to a party with a group of nursing students. We visited the old Manly Quarantine Station and did a ghost tour. I don’t believe in ghosts but I did enjoy hearing all the macabre stories from yesteryear. One recurring story was of visitors being followed at night by disembodied blazing red eyes. I got bit of a surprise when I checked my photos the next day.”

“Supposedly the nickname stems from the fact that many people have been known to enter “the Triangle” for a swift half, only to disappear for days on end, emerging confused and with little memory of what has transpired. The locality has been noted for its frequent ghost sightings.”

This new standard was more efficient because it used lower voltages (-6V to +6V vs. -15V to +15V) and differential signaling to handle faster signal transmission.

“I decided to make a slow-motion capture of the corridor lights flicking on and off. I shot several clips over a twenty minute period. As I reviewed the footage, I became aware that some shots had the figure of a little girl standing at the end of the corridor, seemingly looking at me from around the door.”

Pin4/ DTR (Data Terminal Ready) – The second pin receives instruction from the PC to prepare the MODEM to connect with a telephone circuit.

This standard divided the pins into control, transmission, and ground pins to handle the connection and data transfer between the devices.

We use an MAX232 converter chip to connect the controller to the female RS232. The communication voltage can range from -15V to +15V or from -1 volt to +12 volt.

Pin6/ DSR (Data Set Ready) – The MODEM often instructs the DSR to inform the PC of its readiness to receive and send data.

“I was pottering in my studio which is located in the basement level of my building. Now part of the postgraduate art school here in Glasgow, it once was a hospital as is very apparent from its slightly imposing medical trappings.”

DE-15 connectors replaced DE-9 for analog video (VGA, SVGA, and XGA) transmission to monitors and projectors. The connector also provided a serial link for game controllers like joysticks.

Inspired by an early silly season spate of spooky ghost stories in the press, we asked our readers to provide their own ghost pictures. We asked this despite knowing full well that ghosts aren’t real, as comprehensively proved by the BBC’s Ghostwatch investigation in 1992.

“Indeed, it has been proposed that a pale, squinting gentleman regularly spotted nearby, sporting a pointy beard and silken breeches, might not be a local art student as first thought, but rather could be none other than the phantom of murdered Tudor playwright Christopher Marlowe himself!”

You have to hand it to this ghost. Unlike the other ghosts on offer, it looks like a ghost. But it loses points for being seen during the daytime, as no self-respecting ghost ever would. Also, it’s joined this tourist snap a little too readily to convincingly be a tormented soul, trapped between this world and the next. And yet. And yet...

Our first ghost comes all the way from Australia, where hauntings by spooky apparitions are given an extra fright factor by being upside down.

“If you look closely in this picture, you can make out a ghostly figure standing in the middle-left window of the pub, just above the sign,” claims endymionsleeps.

Unlike the other two, this standard defines the electrical characteristics of receivers and drivers in serial communication.

A DB9/RS232 connector pinout comprises nine pin connections arranged in its port. Initially, it was a 25-pin port terminal, but you can now find a 9-pin terminal.

RS232 devices often use serial communication data with a bit-by-bit exchange of data. Moreover, it's a nine-pin connector piece.

Companies like Apple initially used a 9-pin D connector to connect Mac computers to AppleTalk networks and peripheral devices. But later versions had an 8-pin mini-DIN plug.

EP Goodwin · 2006 · 258 — A Ronchi test uses a low-frequency grating, called a Ronchi ruling, in place of the knife edge in a Foucault test or the wire in the wire test.

RS232 connectors operate in several applications. For example, their connection plays a role in personal computers' uninterruptible power supplies and data storage. You can also find them in modems, which are peripheral devices.

“This poltergeist appeared behind us during this photograph taken at the South East Asia games in Singapore at the National Stadium in Kallang, says Jason Elliott. It’s not a poltergeist.

Unlike RS422, RS485 supports a true multipoint network because it allows a maximum of 32 drivers and 32 receivers. RS422 can only handle one driver and ten receivers max.

“On our way to the top of Blarney Castle, I snapped two pictures of a dark cave carved into the side of the castle which was used to house prisoners,” says Alexandra Bacchetti

RS-232 communication

The IC converts high-voltage RS232 signals to TTL and vice versa. Since the varying voltage level doesn't suit sensitive electronics, the MAX232 chip becomes a mediator. So, without it, you can cause permanent damage to one of your devices.

“There is no light source in this cave. After examining the picture afterwards I surprised what showed up. First I thought something was wrong with my camera, but pictures before the snapshots and after the snapshots where fine. The other picture shows streams of misty light descending from the roof of the cave and bouncing off the cave floor.”

DaLeftHook left nothing to chance, and dared friends (note: not himself) to go to Long Beach Cemetary at midnight. These brave, unnamed friends took this picture, apparently of a gravestone. They were never seen again.

RS485 balances electrical signaling and supports multipoint systems, allowing multiple drivers and transmitters to communicate on the network.

Now this is more like it. A sinister outline of a child. This must be a ghost, surely, just like this one in the Mirror, which turned out definitely to be a ghost. Tim Sandys takes up the story.

“A possible otherworldly origin is seemingly suggested by the fact that this patch of South East London is especially renowned for its spooky goings on. The photo is taken outside one of a trio of drinking establishments known locally as “the New Cross Triangle.”

Its design allows data exchange between Data Communication Equipment (DCE)/MODEM and Data Terminal Equipment (DTE)/ PC. Again, it solves the challenge of parallel communication.

The original RS232 standard introduced in 1960 specified this 25-pin D-subminiature connector to connect DTE and DCE devices.

Straight-through or crossover cables (null-modem), with the most common type being straight-through. This cable connects Data Terminal Equipment (DTE), such as a computer, to Data Circuit Terminating Equipment (DCE), such as a modem.

“Taken at Chistlehurst caves in Kent whilst with my two young daughters,” says this anonymous reader. “Noticed the image when I uploaded it to my laptop.”

“The quality of the image, the history of the building and the fact that it creeps most people out late at night, all these pandered to the arcane narrative; the familiar trope of a ghost story. I suspect someone was working up on the second floor in Printmaking. They likely had their bored child along for the ride who decided to go exploring downstairs and was greeted to the site of some creepy guy with a phone.”

You’ll need a USB to RS232 converter to handle this connection. The converter connects to your computer via the USB plug, while the other end (RS232) hooks up to the RS232 device via a multi-pin serial port.

This interface can link unlike (DTE to DCE) or like devices (DTE-DTE or DCE-DCE) using straight-through or crossover cables.

Although the standard specified the DB-25 connector, manufacturers could customize the interface because RS422 focussed on the electrical characteristics of the signal transmission.
