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.

3. ARCHITECTURE OF ACT-IR100SD
The mandatory IrDA protocol layers, IrLAP and IrLMP (including IAS) are handled by ACT-IR100SD, In
addition, TinyTP, IrCOMM, IrLPT and OBEX transport are also included.
The incoming/outgoing IrDA user data payload are buffered and then transferred to/from the host. The
baud rates of IrDA traffic and host interface are independent of each other. The flow controls of IrDA
traffic and host interface are also independent of each other.

4. HOST INTERFACE
The host interface of ACT-IR100SD is a full-duplex asynchronous RS232 DB9M connector. The following
table is the signals of DB9M connector. It can be treated as DTE. The data bytes are transmitted via TXD
pin and received via RXD. Each data byte consists of one start bit (0), 8 data bits (LSB first, MSB last), a
stop bit (1) and no parity bit.
Implementing H/W flow control signals in host end is recommended. Since ACT-IR100SD is a buffer
limited dongle. Without flow control will probably cause data loss sometimes. The H/W flow control
relative signals are: DTR, RTS, DSR and CTS, which are defined exactly as RS232 DTE interface.

4.1 Host Interface Signals
ACT-IR100SD host interface consists of three output signals and five input signals. All these signals are
low active. That is, they are at 0V when active and at VCC level when inactive. When an inverting RS232
level converter is used, the corresponding RS232 level signals are high active. That is, they are at +12V
nominal when active and at –12V nominal when inactive.
4. /TXD: serial data output.
2. /RXD: serial data input.
3. /RTS: output. When hardware flow control is enabled. Active /RTS means /RXD is ready to
receive. Inactive /RTS means /RXD is not ready.
4. /CTS: input. If hardware flow control is enabled, /CTS must be driven active to allow /TXD and
inactive to forbid /TXD. If hardware flow control is disabled, /CTS is optional.
5. /DSR: input. If connection control is enabled, /DSR must be driven active to allow IrDA connection
and inactive to forbid a new connection or terminate an existing connection. If connection control
is disabled, /DSR is optional.
6. /DTR: output. If connection control is enabled, active /DTR means an IrDA connection is made.
Inactive /DTR means there is no connection.
7. /CD: input. Optional.
8. /RI: input. Optional.

5. OPERATING IN ACT-IR100SD
5.1 How To Connect IR100SD With Host Device:
IR100SD uses a standard RS232 DTE port to connect with the host. If the host device is a Modem
like device and has a RS232 DCE port, then use a "straight cable". That is, connect the signals with
the same name from one side to the other.
All the operating procedures of IR100SD are triggered by DSR signal from HOST, (DSR for IR100SD
is an input signal.) except DSR is ignored by PC utility, see section 5.2 below. When DSR is pulled
high level (RS232 level) by HOST, IR100SD will send out discovery frames to outside and try to find
some other IrDA devices if IR100SD is set to Primary mode. Or it is ready to receive discovery frame
from another Primary device outside if IR100SD is set to Secondary mode. It depends on what mode
is operating in IR100SD.
When IR100SD is connecting to another IrDA device successfully via IR, it will pull DSR signal to high
(RS232 level), which also means that Host can send and receive data frame to and from another IrDA
device. When DSR is pulled to low, it means that IR link is not established anymore.
5.2 How To Configure The Role Modes And The Other Parameters In ACT-IR100SD:
Since ACT-IR100SD supports Primary, Secondary and several parameters, Comset_IR100SD.exe is
an application associated with the dongle for customers to configure the dongle themselves.
Please attach IR100SD dongle in PC then execute Comset_IR100SD.exe in Windows system. It will
show three pages of parameters for change. After any parameter is changed, you have to press
“send” button on every page you change first. Then press “Save Config into Flash” so that
parameters can be configured successfully.

User’s Manual
5.2.1 The first page is to set the host baud rate and the hardware flow control.
Please Note:
Ignore CTS: If host device has no hardware flow control signals, only Tx, Rx and GND, then you
have to set this bit to 1. IR100SD will pass the coming data to host and doesn’t care the
status of CTS. Note: Since IR100SD is a buffer limited dongle (2K bytes for host and 2K
bytes for IrDA), if this bit is set, then it will cause data loss (Because no flow control).
Where data loss can be solved if user sends data by segment and every segment
doesn’t exceed 2K bytes.
Ignore DSR. If host system has no DSR signals, then this bit should be ignored. But since this signal
triggers IR100SD into Primary mode, it will be no way to ask IR100SD disconnecting
IrDA link. And IR100SD will always be in Primary once power on. In other words, once
D4 is set to 1, you are not able to control IR100SD at all until power off and reset D4 to
0. This bit is recommended being set when host device is in Secondary mode.

5.2.2 The second page is to set time interval of discovery, the slot number of discovery and the mode
of IR100SD.
1) IR100SD supports both Primary and Secondary. It allows customer to change it.
2) Discovery time should be 3 seconds in general. If you want the discovery process faster, you can
change it.
3) Discovery slot can also make discovery process faster.

5.3 OBEX PUT/GET Description
The OBEX specification consists of two major parts: a protocol and an application framework. This is
also illustrated graphically below. The "application framework" is represented in ellipses inside the
"wide word of applications" at the upper half of this figure. The "protocol" part is presented in five
rectangles at the lower half of this figure.
Standard ACT-IR100SD doesn’t and can’t provide the "application framework" part of OBEX in the
"wide world of applications" (the ellipses in Figure). The host system using IR100SD must implement
that part by host itself.
Now IR100D-OBEX-Server provides PUT/GET server in OBEX, user doesn’t need to handle OBEX
command and response anymore.

The following figure shows how cellphone or PDA delivers an object (maybe a phone book record, a
picture or a formatted data) to user’s host. When IR100SD-OBEX-Server receives OBEX PUT command,
it will act like a PUT server and reply proper response. Then it will trim PUT commands sent by cellphone,
only left object data itself and then pass to user’s host. While transferring objects, user’s host is not able
to know how big this object is until it receives the entire object.

Since IR100SD-OBEX-Server can only handle server role in OBEX, so user’s host can’t deliver object to
cellphone directly. The following figure is showing how cellphone or PDA gets some object from user’s
host. They have to give GET command to IR100SD-OBEX-Server. IR100SD-OBEX-Server will wait data
coming from user’s host and create response for GET command.

Please note that based on OBEX requirements, when user’s host is going to send data to
IR100SD-OBEX-Server to response GET command, user’s host should tell IR100SD-OBEX-Server how
big the object is first. So there is a formatted frame that user’s host should obey when it sends this object.
