USB to Serial RS422/485 Converters
£51 for this one... I'm sure you can get cheaper ones.
Whats a S422 Converter? Do they cost £145? :/
I've bought a serial to TCP-IP converter from these people. I'd recommend them as knowledgeable, and their kit as "doing what it says on the tin".

If it’s RS-422 its just one of the serial standard – same family as RS232.
What its converting from/to?
Oh my goodness is that it!?
It part of a quote we've just had for a cashless system! As well as £135 for a webcam! lol
£135 for web-cam? * chokes *
Where are they buying it from? PC-World?

lol @ PCWorld...i had that reaction when i saw the price!
The funny thing is i sat with the guy whilst he did his sales bit. I obviously came across a bit gormless.....or maybe its because im a female...
Price up the componenets yourself from Google and then query the price differential!
There is no better way of getting my back up than (usually young) male sales nerds assuming that I'm a dumb female. The guy who who tried to tell me that I was was wrong when he sent a cabinet that didn't fit the switches we'd ordered from him nearly died. The cabinet sent wasn't the one on the quote, but he wouldn't accept it. I informed him that origami was not helpful to the function of switches... and then demanded that he put his manager on the line.
I'm looking forward to questioning his £135 webcam
I have, on the rare occasion that I've phoned a company for tech help in installing their software, been told to "ask the IT guy at your school". The surprise in their voice when I tell them I'm the Senior "IT guy" is worth the phone call!
What do they need the converter for too? It sounds like the sort of thing they'll stick on a quote hoping you won't query its presence, but that you won't actually need. Most kit would have USB connectors these days, surely?
This sounds like motor-mechanic budgeting. When I was a teenager it was known as "being Appleyarded" as the local Appleyards British Leyland (shows my age ) dealer had a bad reputation for adding things onto the bill that they hadn't done or that they hadn't fitted.
lol! I will do.
Admittedly they were added to the "recommended options section" but still added to the final price..
I cant think what would be serial on a POS these days....even the biometric thingy must be USB?!
The cam is a complete waste of time. Apparently its so you can take a photo of the new kids for the system. But as they are not allowed to write to our SIMS database its only held locally on the machine so in my mind a pointless exercise as we might as well add them to SIMS.
My daughter's school uses the SIMS picture on the cashless dining cards. Don't know what their system is though.
Son's school uses a generic card with the school logo on.
I'll place money it's an RS422 adapter, which is a less-commonly used serial standard, commonly used to connect POS receipt printers up to a terminal. This caught me out a few years back when I brought a receipt printer from e-bay with the intention of getting our helpdesk to print out little tickets we could stick on machines in the workshop, so we know why they're there etc. Of course, I couldn't get it to work because it's a different serial standard, although at the time I didn't realise that - it was only a few years later when I found it in a box and had another go I realised why it didn't work. Doh!
ahhhh!! Thanks for that maniac!
Just flicked through quote....the convertor is there but no receipt printer! lol
