Re: Comms link setup - Com Port Numbers

Re: Comms link setup - Com Port Numbers

I use a laptop with 3 usb ports. It is up to you what "name" you will give to each port. I have named the first usb connector "com1" , the second "com2" and the third "com3". I have done this using the Windows 10 device manager. I use to have a connection betw...

Re: 3D printing of Psion II parts.

This is the newer printing. As you can see there is no clip. It is fitted very well and very tight on the slot of the organizer. They forgot to close the hole for the power adapter completely but anyway this is not the final shape of the comms link case for the USB comms link. I am waiting now for a...

USB Comms Link

Hi to all.
I think that using the usb comms link for Psion II organizer, we don't have serial communication.
Am I right?
If I am not, can anyone tell us what is the pin setup for a micro usb connector in order to have serial communication (TxD, RxD ,GND)?

Store a Psion II organizer with or without battery?

Hello to all.
I would like to ask if we don't use a Psion II organizer for a long time,
it is better to store it with a battery or without battery.
What is your opinion?
