NET232CC_2_1500X1500

Part Number: GC-NET232-PLUS-CC
MPN: GC-NET232-PLUS-CC

YOUR PRICE:  $99.95

The NET232+CC is a serial to Ethernet device server, especially designed for use with equipment following the Cisco® RJ45 console port pinout. The NET232+CC provides remote access over Ethernet TCP/IP to routers, switches, servers, and other equipment that have a serial RJ45 console port or management port. Any Cisco equipment that uses the Cisco 72-3383-01 (DB-9 to RJ45) Console Cable can use the NET232+CC.

Examples of Cisco products that use this type of console port are the Catalyst® 2350 Series switches, Catalyst 6500 Series switches, and the Cisco ASA 5500-X Series firewalls. Other manufacturers use the same RJ45 pinout as the Cisco console port. For example, the IBM® Power 710, Power 730 and Power 8 Servers have a system port that can be used with the NET232+CC.

The NET232+CC is a fully featured device server supporting multiple TCP connections (up to 4 TCP or a mixture of TCP and UDP), DNS, email serial triggers, email authentication, and 256-bit AES encryption at no-additional charge. Serial data rates up to 921K and auto-sensing 10/100Mbps Ethernet are supported. The NET232+CC also features an industrial grade temperature range, detailed LED status indicators, and a factory reset button (accessible through a pin-hole with a paperclip)

The NET232+CC is simple to configure using the provided installation software and web page. Just connect the adapter to an RS232 based RJ45 Serial port and to the local Ethernet network and then run the free software to find and set up the NET232+CC. The NET232+CC is typically used to connect the console/management/system port over the network to a TTY console terminal program such as Hyperterminal. “Virtual” COM ports can also be created on a PC using the included Comm Port Redirector software.

The NET232+CC can be powered from a nearby USB Port by using the optional “USB to Barrel Jack” cable. This cable simply takes the 5VDC power from the USB Port to power the NET232+CC. Power can also be optionally provided by a wall supply (US 110V or Euro 220V).

10 Internet of Things (IoT) Design Considerations: Power and Size

5. Power

Power considerations need to be made when connecting a product to the IoT. Products already using a wall outlet will not have an issue. Manufacturers of products not using a wall outlet will have to consider how their power source will affect their product’s design.

IoT devices running on batteries will have to make hardware decisions based on power conservation. There are also a variety of different types of batteries to be taken into consideration: alkaline, lithium (rechargeable) and coin. There are also AA, AAA, coin cell, C, D, 9V, or custom batteries to choose from. As noted earlier, wireless technologies have different power requirements based on use-cases. Once a manufacturer understands how long and how often a device will be connected and the wireless network is chosen, a properly sized and type of battery can be chosen.

Another source of power for Ethernet-based devices is Power-over-Ethernet (PoE). This technology is popular for low-wattage IP phones and security cameras. Recent advancements and new switching technology is pushing the wattage available through PoE to new levels, thus opening up new possibilities for more power-hungry applications and devices.

6. Size

Many manufacturers start testing the IoT waters by modifying their existing product designs to add networking technologies. Because these devices already exist, many early entrants into the IoT world fail to redesign the product to allow for its newly added connectivity. Fortunately, there are a number of compact modules available for networking technologies that will fit in a manufacturer’s existing products.

These small modules are different though. Some modules are surface mount, others through-hole or pin-header and some still use a specialized mating connector. Also, how the network connector or antenna connector are integrated into the product vary from module to module. Designers must consider the space they have available on their circuit boards and/or in the product’s enclosures to allow whatever technology selected to be used in existing designs.

1. Cost

Connecting products to the Internet of Things (IoT) is essential to manufacturers looking to stay competitive within their industry. Adding IoT capabilities gives consumers more features. It also allows the manufacturer to stay connected with their customer while discovering new product use cases and applications that open them up to new revenue streams. These added benefits for both parties come with a cost though. Connected devices come with higher manufacturing costs but can also be sold with a higher price tag as well.

Wi-Fi and Ethernet connections can be added to products for less than $10 in bill of materials costs. Other technologies, such as ZigBee, Z-Wave and Bluetooth, can be added for a lower price but may require a separate bridge device to get that device on the Internet to access Cloud services.

2. Network

Manufacturers have many hardware and software options when it comes to network technology for their IoT-enabled products. Some devices can be directly connected to the Internet using networking such as Ethernet and Wi-Fi, which are based on the Internet protocol suite (TCP/IP). Other products may use wireless technologies; some of which include TCP/IP, but in the end will require a “gateway” to convert the chosen network to either Ethernet or Wi-Fi. Some of the many technologies available include:

Serial Device Servers

[fa icon='calendar'] Jan 24, 2013 12:38:10 PM / by Jonathan Witthoeft posted in Device Server, Ethernet, General, NET232, NET485, Products, Serial, Serial to Ethernet, WI232

[fa icon="comment"] 0 Comments

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.

What is an industrial network driven on?   What will prepare a network for the future?  Microprocessors are the “Heart of the Network,” according to Jim Montague, executive editor at Putman Media.  “Heart of the Network,” featuring our own Mike Justice, is the featured publication in the fourth quarter 2011 edition of Industrial Networking.

Mike Justice stated, “Microprocessors might be on the lowest layer of the network, but they have a huge influence.”  Chips have evolved from simple standard microprocessors, to application-specific integrated circuits, field-programmable gate arrays, and so on.  Design flexibility is what allows industrial networking to move into the future.

gridARM System on a Chip

Gigabit Ethernet will help industrial networks keep up with the bandwidth requirements for increased network traffic.  Many gigabit products have already hit the commercial network.  It will not be long before the industrial Ethernet networks will need to speed up.  With our new gridARM microprocessor, we are able to supply our customers with a cheap Gigabit Ethernet solution for adding fast Ethernet to their devices.

The gridARM microprocessor is designed for low cost products that require a fast Ethernet connection.  This system on a chip is most flexible because it includes an ARM7TDMI core, 10/100/1000 Ethernet MAC, CAN controller, up to 3 serial ports, I2C, SPI, on chip SRAM, USB device, A/D converters, and interfaces for SDRAM, Flash, Compact Flash, external SRAM, and NAND flash.

To understand why the microprocessor is the underlying technology driving advances in industrial networks and to understand how you can benefit from the evolution of microprocessors, download the full “Heart of the Network” article below.
