IrDA module



Technical details



Some interresting details..........




Wireless GADGET for connection through IrDA:

Did you know that HP has a printer, the HP340 Color, which can be bought including an IrDA-module or -adapter. This adapter can be plugged directly into the Centronics LPT-poort of the printer. It is than possible to print wireless to this printer from your laptop or Personal Digital Assistant like a Psion or Palmtop, but also from your Nokia 6110!!!
But nobody knows that this adapter is just an universal accessory that can be used with almost every motherboard with an IrDA-connector!!! Than it is possible to send/receive files from your laptop or PDA into your operating system without difficult connection of any cable. This is especially useful when you have Nokia Data Suite if you want to edit your phonenumbers, ringtones, operatorlogo and/or profile-gif's. Who doesn't want this when you have a phone like this......... All can be accessed by using IrDA..........

The adapter of the HP340 is a small printed circuit board placed into a turn-able "eye" which is connected to a case which hold the centronics connector to connect to the printer. 

The physical IrDA-interface with al components on board, can be connected directly to your motherboard, NOT to your RS-232 COMx poort, this because the IrDA-interface uses a supply voltage and signal voltage of +5V, the RS232 COMx poort has + and - 12V. 

The only thing you must check, is what signal at which pin is situated on your motherboard. This can vary from system and/or brand so please read the user's manual of your board.


 Pins on the module named, beginning from the IrDA-component (HP1000)  IrDA connector on BE6
(At the underside the pins are numbered) (Pin 1 is situated at the left side of
the header, close to the case)
 PIN 1  Data output form module (5V signal)  RxD  PIN 3
 PIN 2  Data input from module (5V signal)  TxD  PIN 5
 PIN 3  Supply Voltage  +5V  PIN 1
 PIN 4  Data send/receive indicator or slot-pin  +5V for activating LED  PIN 2
 PIN 5  Ground  GND  PIN 4







Pins named on the BE6-motherboard are as follows, beginning from the left side close to the case;

 Pin1  +5V
 Pin2  No Connection
 Pin3  IR_TX
 Pin4  Ground
 Pin5  IR_RX

Then, inside the BIOS, the setting would be:
RxD, TxD Active : Hi, Lo
IR Transmission delay : Disabled

The following section can also be used when you have an Laptop with a build-in IrDA-module which doesn't react.
Also usable when you want to try your Nokia 6110 to use your Nokia Data Suite! Specially for K.v/d V

Also you have to adjust the parameters for the port you want to use in the "Msports.INF"-file which can be found in de windows\INF-directory for your system
The lines you MUST change are found in the following section of this file:

; User readable strings
MS = "Microsoft"
Std = "(Standard port types)"
PortsClassName = "Ports (COM & LPT)"

*PNP0400.DeviceDesc = "Printer Port"
*PNP0401.DeviceDesc = "ECP Printer Port"
*PNP0500.DeviceDesc = "Communications Port"
*PNP0501.DeviceDesc = "Communications Port"
*PNP0510.DeviceDesc = "Generic Ir Serial Port"
*PNP0511.DeviceDesc = "Generic Ir Serial Port"

Normally the last two rows here mentioned have an semicolon at the beginning. Remove this semicolon and the row will be execute by the operation system. Don't forget to make a copy of the original file and save the file you changed with the same name.

Now reboot your system!

Now with Windows 95/98 you can then configure your system to send and receive files from different external sources........

After installing the standard drivers and rebooting your system you can test your IrDA-module bij starting the IR-Monitor in the control panel. But don't use this when using Nokia Data suite, because you will have a conflict in your system.

Even testing with your Nokia is possible
First you get the following message......

Then the system will check the maximum speed.......



Accessories like these are mostly expensive because there is a small market for it. ActiSys, ASUS, A-BIT, BayBeamer and JetEye are some brands who has some IrDA-modules you can buy, for both motherboard or COM-poort connection. But the price is not low;
> Fl. 100,=
Conrad has a module you can buy, Fl. 159,= excl. p&p. (
Look at the photo's I made from my system, there will be more soon...........

Thanks to, and with the full permissions of, F.v.R, head of the office which supplied the IrDA-module, I wrecked this IrDA-module to place this into my machine.
