2. OVERVIEW
The ACT-IR100SD is a high-integration IrDA Intelligent dongle. It provides a serial interface to a host
device that intends to have Infrared communication capability. The host device can be any equipment or
device that needs to communicate with IrDA enabled portable or tablet PC, PDA, cellphone and hand
held data terminal, via IrDA protocol with only a wired serial interface. The ACT-IR100SD will handle all
the detail about IrDA protocols. It sends and receives only user data to and from the host device via the
wired serial interface with hardware flow-control. IrDA has two modes; one is Primary, and the other is
Secondary. The difference between them is that a Primary mode device initiates discover, connection
sequence and negotiate IrDA protocol parameters to Secondary mode device; while Secondary mode
device always waits for commands from Primary mode device. Both modes can run different protocols,
and both may send or receive user data. ACT-IR100SD supports both modes. When IR100SD is set to
Primary mode, user can choose IrCOMM, IrLPT or OBEX PUT/GET server to be Primary protocol via a
simple PC utility. Fig.1 is the system diagram.
