Employee Spotlight: Budd Justice, Shipping

Budd is the lifeblood of Grid Connect. Literally. Being the father of President, Mike Justice, engineer, Steve Justice and the grandfather of Vice President, Adam Justice, he is an important part of the community here.

Grid Connect-5734After Budd retired about 17 years ago, he started working with Mike at what was then called Synergetic Micro Systems. In 2003, when Grid Connect was spit out of Lantronix, Budd was a part of the team of five that worked for six months without pay to get the company off the ground. “It was the only time in my life I was ever unemployed.” Says Budd laughing, “But after that, the company grew in leaps and bounds. When Glenn and Mike developed the NET485 our order list exploded, and it’s been growing every year since.”

Before joining the Grid Connect team, Budd worked for 30 years at a chemical company. In that time he worked multiple jobs, including field engineer, salesman and product manager. Now he manages all of Grid Connect's orders, boxing and shipping every purchase that comes in. “We only hire a certain caliber of person here,” Budd said when asked about his job, “it makes the place have a great atmosphere.”

Budd loved volleyball when he was younger, and even played on the Illinois National team for seniors until he was 65.

Common Questions about Grid Connect Products

Jul 27, 2015 3:57:46 PM / by Brittney Borowicz posted in CYT-133SC, FAQs, General, Grid Connect, Lantronix, NET232, NET485, Products, Technical Support


New products can be confusing: directions can sometimes be tricky, or devices may not work the way that they seem. This is why we try to provide as much technical support for our products as possible. We provide clients with the expert support of our engineers to ensure that our products run smoothly in their hands.

Our technical support engineer, Matt, tends to get asked certain questions more often than others. So from time to time, we like to compile these questions for easy access to our customers. Here are a few:

  • I am trying to setup my device using Internet Explorer but it is not working. What can you recommend? Avoid using Internet Explorer to setup devices that use a web configuration page. I recommend Google Chrome.
  • How can I obtain a copy of the product CD for my device?
    All of the CDs we include with our products are available on our website. Visit GridConnect.com, find your product on the website, and the CD as well as other useful materials will be located under "Documentation."


  • For the NET232, NET485, NetDirect products, and Lantronix products, where can I find the latest version of Device Installer or Com Port Redirector (CPR)?
    Those are available on the Lantronix website at http://www.lantronix.com/support/downloads/.
  • Where can I find the latest version of VCOM for ATC products? Where can I find the right version for my operating system?
    Those can be found on the product page on the ATC website at http://www.szatc.com/.
  • Where can I find the latest drivers for the PCAN-USB? Where can I find the latest version of PCAN-View?
    All of the software for the PCAN-USB can be found in the PCAN-USB package on the Peak website at http://www.peak-system.com/fileadmin/media/files/usb.zip. All software can be found on the download page at http://www.peak-system.com/Downloads.76.0.html?&L=1.
  • Specific questions for RS232:
    • Why is the signal blocked on my RS232 Module? On the RS232 modules, be sure to use a null modem instead of a gender changer, otherwise it will block the signal.
    • How do I connect my RS485 serial lines to a computer? RS485 requires either an RS485 to USB or RS485 to RS232 adapter to connect to a computer
  • Specific questions for the Chiyu CYT-133SC:
    • Why won't the Peer-to-Peer I/O function work on my device?
      That I/O function requires a firmware update be performed on the CYT-133SC. This can be done pretty easily through the web configuration page. The firmware files and instructions can be obtained by sending an email request tosupport@gridconnect.com or by calling the office.
    • Does each unit control the other in Peer-to-Peer?
      Yes, the I/O control works in both directions.
    • Am I able to transmit serial data in Peer-to-Peermode?

    • Where can I find the latest version of VCOM for my Chiyu device?
      All software and drivers are available from the downloads section of the Chiyu website at http://www.chiyu-t.com.tw/file_list.asp?cat=124.

If you have any other questions about these products, or any of the other products on the Grid Connect website, please contact Matt at +1 (630) 245-1445 or +1 (800) 975-GRID (4743) for USA Toll Free.

Serial Device Servers

Jan 24, 2013 11:38:10 AM / by Jonathan Witthoeft posted in Device Server, Ethernet, General, NET232, NET485, Products, Serial, Serial to Ethernet, WI232


Serial Device Servers transfer data between a serial port and an Ethernet network.  Some of the most common serial interfaces are RS232 (typically DB9) and RS485 (typically 2 wire).  The most common Ethernet protocol used in serial device servers is TCP/IP.  The NET232, for example, will take RS232 serial data from a 9 pin port, encapsulate it in a TCP packet, and send it on an Ethernet network from a configurable IP address and port number.  This makes it possible to use Ethernet in place of serial cables, which minimizes workstation clutter and also allows serial devices to be used beyond their typical limitations.

Ethernet protocols other than TCP/IP are supported by specialty device servers.  These include, but are not limited to, Modbus TCP to Modbus RTU (NET485-MB) and Ethernet/IP to Modbus RTU (NET485-EIP-MB) device servers.  These require special firmware due to the extra steps involved in not only adding another layer to the TCP protocol, but also adding a serial protocol for sending data across the serial interface.

Device servers make it possible to access distant serial devices as if they were directly connected to the COM port of a personal computer via the internet and virtual COM port software.  They can be used with all types of serial devices and peripherals such as printers, data collection terminals, modems, and automation equipment.   Device servers are available for hard-wired networks, like the NET232, and wireless networks, like the WI232.

Most serial protocols on RS485 allow for daisy chained serial devices.  This is due to the addressing that is in protocols, such as Modbus RTU, which allow serial devices on an RS485 network to only respond to messages addressed to them.  In this case one serial server can control multiple serial devices through address mapping.  The following illustration shows an example where one of our NET485 devices is used with several barcode scanners.
