Why Network?
Tired of chasing floppy disks around your facility? Sending and receiving your designs with e-mail? The double density 720K disks used by embroidery machines are being replaced by other media in the general computer world and are becoming harder to find. By connecting your machine(s) directly to your design computer, you eliminate the need to maintain a floppy disk library and all the hassles that go with it.
Series And Parallel Connection
Is there a maximum distance that 2 Arduinos can communicate with each other using serial? 1 of the UNO's will already be an I2C slave to another I2C master so cannot use I2C. I want to use a UNO to manage display of various types of data collected locally by the other. Tajima TMBU-SC series is an embroidery machine that supports not only regular embroidery such as caps and shirts, but also large products such as golf bags and travel carry bags. TFMX-C Series Diversified applications are available to a wide range and variety of products, using a.
Tajima-Nei distance. In real data, nucleotide frequencies often deviate substantially from 0.25. In this case the Tajima-Nei distance (Tajima and Nei 1984) gives a better estimate of the number of nucleotide substitutions than the Jukes-Cantor distance.Note that this assumes an equality of substitution rates among sites and between transitional and transversional substitutions. Interfacing the Serial / RS232 Port. The Serial Port is harder to interface than the Parallel Port. In most cases, any device you connect to the serial port will need. Tajima DG/ML by Pulse. A new logo can be easily uploaded by connecting a computer to the projector through a LAN or serial (RS-232C) connection by using this. Tajima Machine.
Parallel Connection
We decided to network our machines for the reasons listed above. As we started planning the process, we were unable to find a comprehensive source of information about how to accomplish our objective. As we went through the process, we discovered a few critical elements that caused us needless expense and frustration.
The purpose of this article is to share our experience so others may avoid the pitfalls we encountered. The specifics in this article apply to Tajima embroidery machines and Wilcom digitizing software, but the principles will be similar for other machines and software. Our network consists of ten Tajima machines but the technology works with just one embroidery machine (actually it's easier).

Planning
Like most other projects, the more time spent planning, the less time spent implementing (and correcting problems you didn't anticipate). First, determine the length of the cables needed. Allow at least an extra 5' beyond the minimum length required. Order the cables as soon as possible.
Rs232 Serial Connection
If there is more than one machine to network, decide how to provide the number of serial ports needed. If the number of machines to connect is small, use a PCI card that plugs in a slot in your computer and provides multiple serial ports. For 4 or more machines, a Comtrol multi-serial port device is recommended. Order any hardware needed to provide the necessary serial ports.
Review your software or contact your vendor to see if additional licensing is needed to network machines. In our case, we had to purchase an additional license from Wilcom to control 8-16 computers. Wilcom allows you to control up to 4 machines without additional licensing.
Cables
Tajima embroidery machines have proprietary connections for networking, a standard serial (or null-modem) cable won't work. We found out about this the hard way. Tajima cables (or custom-made cables to Tajima specifications) are needed.
Serial Connection Cable
Custom made cables are a viable option, although usually impractical. Pin layout specifications for Tajima machines are available if a source of custom pinned cables is convenient. Tajima distributors sell serial cables in lengths of 25', 50', 75' and 100'. The longer two cables are shielded and are quite expensive. If at all possible, limit your cable runs to 50'.
We obtained our cables from Pin Point International, but they are available directly from Hirsch International or Tajima West. The part numbers we used are CABLE-DB9-TAJ-25 and CABLE-DB9-TAJ-50.
