NAPERVILLE, Ill. – (August 26, 2014) – Grid Connect (gridconnect.com), a manufacturer and distributor of embedded networking products, has introduced the NET232+, the next generation of serial device servers. The NET232+ helps extend the life and utility of existing RS-232 serial devices by providing a simple solution to enable them to connect to the network via Ethernet and TCP/IP

The NET232+ is a full-featured device server that delivers serial data rates up to 921kbps and auto-sensing 10/100Mbps Ethernet. This product supports up to four TCP connections (or a mixture of TCP and UDP). It also supports DNS, email serial triggers, email authentication, and 256-bit AES encryption at no additional charge. A debug trace feature helps troubleshoot the serial connection.

The NET232+ features an industrial grade temperature range, a factory reset push button, detailed LED status indicators, and an updated configuration web page.

The product is simple to configure using free installation software. Just connect the NET232+ to a serial device and to the local Ethernet network and run the software to find and set up the NET232+. It can be used in pairs to tunnel serial data between them over the Internet, or stand-alone connected to a serial device on RS-232 and to a host computer on Ethernet. The host computer can open a direct TCP connection or use the virtual COM port software.

The NET232+ is backward compatible with Grid Connect’s previous generation NET232 product.

Additional product information and online ordering are available at http://gridconnect.com/rs232-rj45.html.

Application Adaptation - Creative Solutions for Customer Specific Applications

“This product is NOT compatible with your application.” These are the dreaded words that no customer is glad to hear.  Not only were you looking forward to using the device, but now after built anticipation and empty hopes, you are told it will not work.  At Grid Connect  we try to avoid this statement at all costs.  Our technical sales advisory, expert technical support, and vast product versatility give us the tools to make our Bluetooth products work for you.

Recently a customer requested help using our firefly unit with a Siemens DDC.  The only problem was that this DDC required a loop back of hardware flow control pins CTS and RTS.  This is an option normally not supported.

End Device Flow Control Loop-Back

The flow control loop-back is a problem that is normally solved through a custom cable that would be in-between the firefly and the DDC controller.

This was not a possibility for the customer; the firefly needed to be directly plugged into the DDC.  So we tested and came up with a different solution.  We found that jumpering internal pins 6 and 7 of the firefly unit would directly loopback the RTS and CTS pins of the db9.  This is a solution within the firefly and no additional cables would be needed.

Since the jumpers will not fit in a diagonal orientation, we suggest using wire wrapping rather than soldering so not to void our one year warranty.

Serial Simplified: Serial Communications (1 of 3)

Serial Port

Serial data is still being sent today, one bit at a time, just as it has always been for over 50 years. While serial ports may not be as prevalent on new PCs these days, serial is still in use everywhere. The new PC standard USB has more software overhead and requires more advanced processors to implement, so serial will live on!

RS-232

RS-232 can support data rates of up to 920 kbps (normally 9600 and 115.2K are the maximum rates) and is commonly found in 9 or 25 pin configurations, however only three pins are required. Most applications drop many of the less commonly used pins, though some configurations such as a data modem connect every pin for full handshaking capabilities. An RS-232 is a point to point connection made between a Data Terminal Equipment (DTE) device and a Data Communications Equipment (DCE) device. RS-232 has a maximum cable length of 50 Ft at 9600 baud. This limitation can be overcome by transmitting serial data over another medium.  RS-232 ports/cables can be found in factory automation and metering, medical equipment, consumer products, and many other devices.

Advantages of RS-232:

  • Simple wiring and connectors
  • Widely available
  • Low cost
  • Most embedded processor include this interface
  • Software to implement a serial port is easy

Disadvantages of RS-232:

  • Incompatibilities in wiring and configuration between devices
  • Short cable lengths
  • Subject to noise interference
  • Low data rates
  • Many different software protocols

RS-422

RS-422 offers one of the fastest serial data rates at 10Mbps. RS-422 is a multi-drop configuration, allowing for up to 10 unit loads. Its use of voltage differences makes it ideal for noisy environments. RS-422 can support cable lengths of up to 4000 feet, however its data rate lessens as distance increases.

Advantages of RS-422:

  • High data rates
  • Less subject to noise
  • Longer cable lengths

Disadvantages of RS-422:

  • Not as commonly used
  • Unidirectional
  • For most applications, only one transmitter is used

RS-485

RS-485 provides similar speed advantages as RS-422, allowing for data rates up to 10Mbps. It differs in that it is a multipoint configuration, allowing for support of multiple drivers and multiple receivers. RS-485 can support up to 32 unit loads due to its bi-directional interface.

Advantages of RS-485

  • Low cost
  • Immune to noise
  • Multipoint applications
  • Operates on a single pair of wires

Disadvantages of RS-485

  • Not as commonly used
  • Less standardized connectors and terminology
  • Half-duplex master-slave operation

Grid Connect’s Engineering Staff offers deep technical knowledge in all things serial. In addition to offering a wide selection of Serial Products, we can also provide custom solutions to meet your every need. Visit our Website to find that perfect serial product that meets your needs.
