ACT-IR100S Intelligent Serial IrDA adapter FAQ

Q: How to connect the 100s to a modem device?

A: The RS-232C signals of 100s are DTE (Data Terminal Equipment) and most modem devices are DCE (Data Communication Equipment). So you can connect the corresponding signal names of 100s and modem, e.g. TxD to TxD, RxD to RxD, DTR to DTR, DSR to DSR, RTS to RTS, CTS to CTS, etc.

Q: How to connect the 100s to a serial printer?

A: You must check your printerís RS-232 port definition to see if it is DCE or DTE. If it is DTE a cross connection is needed. If it is DCE no cross connection is needed. (Ref. Userís manual, part 4 How to connect)

Q: Originally my device used three wires (TxD, RxD and GND) for cabling communication. Can I use your 100s to replace the cable?

A: Yes, you can. But please take care of the wiring of some signals, such as DSR CTS DTR and RTS.

100s uses two signals, RTS and CTS, for the flow-control between it and your device. Please note that we are not talking about the IrDA flow control between two IR devices, which is done by TinyTP protocol and IrLAP. 100s uses DTR and RTS (true=high level) to indicate that it is POWER ON and able to receive data and your device should use DSR and CTS to indicate that. Because your device does not use the two signals so that the communication program may have no Flow-control or use XON/XOFF (software handshaking). Anyhow you must pull up the two signals DSR and CTS to high and leave another two inputs DTR and RTS not-connected.

Q: Is the RS-232 communication speed setting for IR communication?

A: No. It is for the RS-232 communication between 100s and your device. The real speed of IR communication has nothing to do with it. It can be higher or lower than the RS-232 speed. The IR communication speed will be determined by negotiation of the two IR devices. 100s has buffers for data in and data out and it has its own flow-control (TinyTP) to guarantee the quality of the IR communication.

Q: which mode my device should use, primary or secondary?

A: The default setting of 100s is both Primary/Secondary. It will automatically select a correct mode during IrDA discovery process. That is if the another IR device is a secondary it will work as a primary. If the another one is primary it will be secondary.

Anyhow you have other two selection, set to Primary or Secondary. But please remember the both sides must be different mode.

 If the problem is still unsolved, please contact ACTiSYS technical support.
