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.
