Wireless: Bluetooth interface - Control Engineering

Viator Bluetooth interface is the latest addition to MacTek Corp.’s line of PC modems. Slated for availability in June 2007, this point-to-point modem for temporary connection to HART-enabled field devices will be ATEX- and IS-certified for use in hazardous areas. The modem is powered by a rechargeable battery that can operate 8-10 hr between charges.

Viator Bluetooth interface, the latest addition to MacTek Corp.’s line of PC modems, will be available as of June 2007. The product joins the company’s Viator USB and RS-232 HART PC modems introduced earlier. All require no configuration and are HART-compliant to work with any HART-enabled device.

DTM (device-type manager) software allows use of the modem with FDT (field device tool)-based host applications. Interface software lets the user turn the modem off, check battery power, put it into a sleep mode to save the battery, and cause an LED to flash rapidly to identify which modem is in use. The modem, expected to be used as part of a configuration-management environment, can physically attach to the HART-enabled field device. The modem is HART-compliant. Because it is registered with the HART Communication Foundation, it works with any other registered device. It is said to be easy to use and connects anywhere on the 4-20 mA loop; compared to cables and clips, a wireless connection can save time and shorten troubleshooting. Company offers product help via phone and Web with a frequently asked questions page, documentation downloads, and an e-mail support-request form, if needed. www.mactekcorp.com
