Serial RF Products Comparison Guide - Problem Solver Walks You Step by Step

Getting from Here to There: Serial Communications Systems - When is wireless the right solution? And what are your options? This brief discussion of serial communications systems is a good starting point in your decision making process.

Stepping Up to Wireless - Let B&B Electronics help make the transition to Industrial Wireless Communications

Wireless Adapters, Interfaces, Servers, Modems,
Accessories and Technical Data

In some commercial and industrial data communications applications hardwiring devices together is just not practical. Long distances, inaccessibility and frequent re-location of devices are a few such applications. In cases like these the simplicity, functionality and reliability of B&B Electronics’ wireless products shine through. Whether you need to communicate a few meters or a few miles, convert from any of several serial standards to 802.11, Proprietary RF or Bluetooth, or set up a wireless network, we have the solutions. We have the accessories too, and all the technical support you will need to get your application up and running.

Wireless Quick Facts

The IEEE 802.11b standard sets out the specifications for a high-speed, wireless, local area network that incorporates the TCP/IP protocol stack and interfaces with Ethernet LANs. 802.11b typically uses access points to facilitate communications between multiple clients on wireless and connected wired networks.

Radio modems provide effective solutions for short and medium-range wireless point-to-point, point to multi-point and repeater communications. Radio modems incorporate features such as ‘sleep and sniff’ modes, menu and AT command interfaces and CRC error checking.

Tech Tip: Replace the cable between a computer and a field device with two RS-232/422/485 to Bluetooth adapters. You can configure the link for 300 bps to 920 kbps wireless communication using a PC Configuration Wizard or AT commands from the connected device.
