Capacitance in the cable begins to affect serial communications, typically many manufacturers/devices set a limit of approximatly 15m or 50ft on cable lengths for anything up to 9600 baud, and about 4m for 38.4k. That being said, with decent cable it is easily possible to go longer in tested or non-commercial use, but I would stick to the guidelines for a commercial product, if only to leave an out for support calls. If you really need length, RS232 to RS422/485 converters are very inexpensive, and you can run the differential modes (422/485) over two wires for well over 100m. In your case, 5m really shouldn't be a problem at 38.4, as long as your cable is of reasonably quality.

Tajima DG/ML by Pulse is the perfect embroidery software solution for your business. With advanced. Serial communication and the.tbf. Design Connections. Apply trims between digitized segments based on the distance between them. Automatically insert lock stitches around trims, color changes and stops; this helps. Tajima Serial Connection To Pc.

Almost any shielded multi-conductor cable should work at that distance, and probably three times it. When I was young I railed against non-spec RS-232 hardware, as it made it difficult to reach the maximum distances RS-232 could reach. After all if your driving voltage is 9 V instead of 12 V you lost about a third of your distance right there. I also griped about other perceived shortcomings in the protocol.

Then I read the spec. RS-232 is an interface protocol.

It is not designed for long lengths; it is designed to connect endpoints to more capable communications equipment. RS-232 allows you to connect to a modem that is not on your desk, but the one next to it, even if you have to run the cable high enough that people can walk under it. You can even cheat and build a passive modem to connect two computers on the same bench out of paperclips (use the plastic coated ones, they don't need bubble gum as insulation). The rule of thumb is: if you have to measure the distance, don't use RS-232; use RS-422/485 or fiber optic instead. RS-232 is however still a good choice for connecting your endpoint to your RS-422/485 (or fiber optic) repeater. And then there are the various versions of the RS-232 spec, A, B, C and now D is common which requires a lower drive voltage. I am glad you found peace with the interface specification.

Transformer (or optically) isolated line drivers are the way to go for distance, company I worked for made a range and sold them to the banks for ATMs as the imported line drivers were not isolated and failed under harsh African conditions (lightning, dirty mains). They did 2 km with synch comms at 19200 and failed only with significant lightning incidents but protected the end equipment. – Aug 27 '15 at 21:48. Too long is defined by your acceptable error rate.

My experience is that the lower the baudrate, the longer distance it will work. Valentino Rossi The Doctor Fontanez more. The company I work for installs rs232 runs longer than 100 feet using cat5, then just adjusts the baud until it works properly, which could end as low as 9600. To figure this out, you could put a loopback on the far end and use the legacy digi xctu tool, which has a range test tab that can do this sort of thing. However, this may not tell the whole story, as the far end device may have different receive characteristics. Yes ground differences can be a real problem but this is not inherently a function of distance. Usually it related more to different device grounds (mains circuits) or other large circulating ground currents.

RS485 is in many ways more sensitive to bad grounds as it has lower common mode voltage limits and is often implemented without a common ground wire which is not good unless it is galvanicly isolated. UTP Ethernet is nice because it is transformer isolated differential signalling. – Aug 27 '15 at 21:41.

Four factors determine the length that can be used: 1) Quality and type of the cable, and the speed and protocol used, as described above.

I have a fairly old Tajima TMFX-C904 that has been playing up for ages with floppys not loading:-( I have got hold of a tajima serial/parallel cable (not sure which it is) from another local embroidery company so that I can try hooking it up to my PC for a direct connection, my question is how do I go about it? Do I have to find drivers for the Tajima online somewhere? As how does the PC know where to send the files to!!! And what settings if any will need changing in my Tajima? This is all a bit confusing to say the least and I'm normally quite good with tecky stuff!! Please someone throw a little light on this headache for me Thanks in advance guys and girls!!. DISCLAIMER: This may or may not work to transfer designs to tajima's via a serial connection!!!

No clue if this will actually work with your machine or not but similar settings work very well with Toyota embroidery machines so it's worth a shot. Stealth Attraction Download Richard La Ruina. Download and install Embroidery Fonts Plus: Configure your computer's COM port. To do this(assuming Windows XP), goto Windows 'Start' -->'Control Panel' -->'System' -->'Hardware' -->'Device Manager' -->'Ports' -->'Communications Port (COMx) - where 'x' is a number typically COM1, and then 'Port Settings'.

Bits per Second: 9600 Data Bits: 8 Parity: Odd Stop Bits: 2 Flow Control: Hardware Run EFP, goto 'File' -->'Open' and choose the DST file you wish to load. It should open in a black box inside of EFP. Go back to 'File' -->'Send to' -->'Tajima Emb. Machine' -->'Via communication port' On the embroidery machine, enter the command to accept a file from the serial connection. Consult your operator's manual for the specific sequence to use to accept a file over a serial connection. Maybe use a 3 or 4 SET instead of the 5 SET used with floppy disks.

Cross your fingers and hope the data transfers. After receiving the file, control will be returned to the operator and it's time to enter your needle sequence. Hopefully that will work. If not, you're only out some time it takes to download, install, and configure some software. Old tmfx machines have parallel port to load the designs. You need an software( ex.Pulse Mosaic-you must use only windows 98) and an special parallel cable.

If you want to change fdd with usb drive you must ask if is possible to install machine software using this usb drive. I know only one with this function made by Richpeace. Also you can buy from Hirsch TUL 01 for parallel connection(is an external usb reader) but with an external device (reader or computer) is not possible to install machine software. I'd try the $30 ebay option first. They are just floppy drives. This isn't rocket science as much as these companies would like you to believe it is. Those same emulators go in musical keyboards and who is gonna spend $300 bucks on a $200 keyboard?

So when they sell to that market the price it accordingly ($30 bucks) but when it's for a $5k-$15k embroidery machine then we 'expect' to see prices like $300 bucks and we won't balk at that and assume they 'know what they are talking about'. But in reality it's the same thing as the $30 one. Supply and demand at it's finest.
