Introduction

NetStreams

ships drivers for a variety of third party systems with the DigiLinX™

system. These drivers include Lutron

for lighting, Aprilaire

for HVAC, and GE

Concord

for security. Custom installers can use these included drivers with a

ControLinX

™

to enable DigiLinX

control of external systems. Sometimes, the

specific needs of a job require DigiLinX to control different third party systems. The

NetStreams StreamNet

™

device driver Application Programming Interface (API) is

designed to enable programmers to interface RS-232 and network devices with the
NetStreams DigiLinX system. This gives custom installers the flexibility they need for
their jobs.

The DigiLinX system is a combination of hardware, software, and firmware. To
understand how to interface third party systems with DigiLinX, programmers must
understand the architecture of the system (see Figure 1-1).

In the DigiLinX system, the hardware layer is controlled by firmware. Firmware is
controlled and updated by software, which in turn is controlled by configuration files,
and drives the User Interface. NetStreams’ engineering team has created an API that
