ProComSol Releases Extended Range Bluetooth HART® Modem


LAKEWOOD, Ohio USA – ProComSol, Ltd today announced the release of the HM-BT-BAT-ER (HART Modem, Bluetooth, Battery Powered, Extended Range). With a list price of $349.99 (USD) it is the lowest cost Bluetooth HART modem available to the market. This product is an upgrade of the popular HM-BT-BAT which was the first Bluetooth HART modem, available since 2005. “The freedom of movement that Bluetooth offers is a tremendous advantage to HART professionals. Now smaller, with a longer range, and with a built-in rechargeable battery, the modem is even more convenient”, says Jeffrey Dobos, President of ProComSol, Ltd.


By reducing the wiring requirements, and by its small size, lightweight, and durability, the HM-BT-BAT-ER is ideal for portable field use. Productivity and safety are increased when the PC is not tethered to the HART instrument. Access HART instruments while safely on the ground. Instead of balancing a laptop on arms and legs, it can be placed securely on a table or chair up to 150’ away. There are no wires to the PC to tangle or trip over.


The HM-BT-BAT-ER meets industry standards for both Bluetooth and HART connectivity. The Bluetooth interface meets Bluetooth v2.0 standards and is registered with the FCC. The HART interface meets the HART physical layer specification HCF_SPEC-54.


No additional software drivers are needed to use the HM-BT-BAT. After a onetime Bluetooth Discovery operation, the modem appears as a Serial Port to the operating system. This allows any software package to interface with the modem. This includes Personal Data Assistants (PDAs).


The built-in rechargeable battery will last 14 hours between charges. The modem has a mini USB connector for recharging. You can recharge the modem from your PC using the included USB cable, or from your truck using an optional vehicle charger. Any cell phone charger with a mini USB connector will work also.


Datasheets, User Manuals, and Test Software (also for the Pocket PC) are available on the company website, The website also contains an online ecommerce site.
