Device Connectivity

Medical Device & Healthcare Connectivity

Device ConnectivityAs the healthcare industry continues to embrace cutting edge technology as a means of cutting costs, the need for effective connectivity has become an important feature for many medical device and instrument vendors. USB

Hospital Information Systems – HIS

The need to integrate and distribute information throughout the hospital and laboratory has become one of the biggest challenges for managers of HIS and LIS systems. BAT recognizes these challenges and has worked with some of leading point-of-care companies to develop reliable ASTM and HL7 interfaces. BAT has successfully developed and deployed ASTM HL7 interfaces in some of the largest and busiest hospitals in the US and Europe. We have extensive experience developing ASTM and HL7 interfaces for point-of-care testing medical devices including blood gas analyzers and glucose monitors. We also offer integration and validation services to ensure a successful deployment of the interface. BAT has experience developing HL7 interfaces for both TCP/IP and RS-232. Our experience developing HL7 interfaces includes:

Patient Order Management

The HL7 communication protocol provides a set of messages to receive, process, and transmit patient test orders. Patient order messages contain information that uniquely identoify the patient to the HIS and test order criteria. Patient orders are centrally generated from the HIS and transmitted to a medical instrument via the HL7 protocol. Once the test has been acquired at the instrument, the test results are transmitted back to the HIS. This portion of the HL7 protocol provides critical capability for the HIS including patient test results and to facilitate the hospital billing system.

Admit Discharge Transfer - ADT

Admit Discharge Transfer or ADT is an important part of the HL7 communication protocol. ADT messages are trigged by the HIS based on patient related events such as a patient being admitted, transferred, or discharged. Each ADT message carries demographic information to uniquely identify the patient and information regarding the patient’s status such as a transfer from one department to another or even a change in patients assigned bed. The nature of the ADT protocol is continuous and verbose. In most deployment scenarios an ADT interface with an HIS will result in a large volume of network traffic to medical instrument. If the proper message handling approach is not employed the volume of ADT data can overwhelm an instrument. BAT can design a custom ADT interface for your medical device or instrument.

Connectivity for Industrial Automation

Automation control has become a major considering when companies choose a piece of industrial equipment. Industries such as HVAC, fire deduction, lighting control, and security all embrace the use of standard protocols for automation control system. Communication protocols inclduing Modbus and BACNet have been adopted as the standards for these industries.


The Modbus communication protocol has its roots in Programmable Logic Controllers or PLCs and is commonly used in industrial automation and control applications. The Modbus protocol is designed for master/slave architectures and is universally accepted as a standard protocol in industrial automation. Because Modbus is a transport layer agnostic protocol, Modbus supports both TCP/IP and serial (RS-232, RS422, RS-485) communications. BAT designs and develops Modbus interfaces for industrial controllers for safety critical applications. We also provide validation and integration services to ensure a successful deployment for you and your customers.


Building Automation and Control Network or BACNet is an open industrial control and automation network protocol. BACNet is widely accepted as the communications standard for automation control in HVAC, lighting control, access control and fire detection equipment. BACNet implementation exists for TCP/IP and serial (RS-232, RS-422, RS-485) communications. BAT designs and develops custom BACNet interfaces for a variety of hardware platforms. By providing integration and validation services, BAT can assure a successful deployment and software reliability.
